Do pressure washer marks go away?
To fix pressure washer marks in cement, try spraying on some muriatic acid and scrubbing it quickly. Then pressure wash with a fan nozzle. A solution of muriatic acid will etch the cement and camouflage the marks.
Can a pressure washer damage a deck?
If you have timber deck boards, a power washer’s pressure may cause splintering and damage to the timber fibers. If the timber surface already has some splintering, pressure washing will only exacerbate the issue.
How do you treat a deck after pressure washing?
After you’ve pressure washed your deck, you’ll need to wait for it to completely dry. Sometimes, this can take as long as 48-hours. Once it’s dry, you’ll want to sand your deck lightly. This is necessary to remove any splinters or fuzzy patches that pressure washing can cause.
Why is my deck fuzzy?
Pressure washing removes the outer layer of dead wood, and can sometimes make it look like it has short fuzzy hairs. This is caused by the tearing of the wood fibers. This is normal, and does not indicate damage. These fuzzies will generally go away in 2 or 3 weeks.
Why You Should Never Pressure Wash Your Deck
Can I use bleach to clean my decking?
Window Genie never uses bleach on a patio and we do not recommend that you do so. Bleach kills mold well, but nothing against dirt. Think about what you use when doing your laundry; You can use bleach as a bleach, but you’re still using a detergent to clean your clothes.
Bleaches are used by papermakers to break down lignin, which is the natural component that holds wood fibers together. Excessive bleaching will do the same to a deck. When this happens to your patio, the wood fibers appear loose. With continued use, you can actually tear the wood apart with a gentle squeeze of your fingernail. Additionally, when used in strong enough concentration, bleach can attack iron nails, nuts, and bolts that may be holding your deck together. Not sure!
When purchasing a commercial deck cleaner, check the labels for sodium hypochlorite or calcium hypochlorite. These ingredients are just technical terms for bleach and will do the same harm as the bleach you buy at the grocery store. Also, don’t be fooled by “buffered bleach” claims. Even with fancy names, bleach is still bleach, and it’s always harmful.
Can I high pressure clean the deck myself?
There are several low-power pressure washers that are marketed directly to homeowners. A pressure washer is not difficult to use. HOWEVER, it is very easy for an untrained person to damage the wood with too much pressure. If you’ve never used a pressure washer before, experiment on some old pieces of wood first. If you have a second story deck, you might be able to practice on the bottom part that isn’t visible. If you also use a chemical cleaner, you can clean the deck with a lower pressure. The water pressure in pounds per square inch (PSI) typically used in cleaning decks ranges from 300 to 3,000. Window Genie uses an average of 1500-2000 PSI depending on the nature of the wood. Cedar and redwood require much less pressure.
If you’re buying a home pressure washer, chances are your only option is cold water. That’s okay. Window Genie uses and recommends cold water for wood surfaces. Heat causes the wood to expand and this leads to excessive water absorption which is harmful to the wood. Hot water high-pressure cleaning on wood is only suitable where heavy grease stains or seals need to be removed. In this case, you should consult a professional. High pressure hot water washing requires a trained professional.
Why does my wood look fuzzy after pressure washing?
Pressure washing removes the outer layer of dead wood and can sometimes make it appear as if it has short, fluffy hairs. This is caused by the tearing of the wood fibers. This is normal and does not indicate damage. These blurs will generally disappear in 2 or 3 weeks. It’s okay to apply sealer over fuzzies.
Fuzzies can also be removed by light sanding. Depending on the extent of the damage, a kitchen scrubber or pool brush may be enough to even out the damage. If the fuzzies are deep and more extended, you can use sandpaper or bronze wool. We recommend using bronze wool as opposed to steel wool as it will not stain rust. Scrubbing your wood deck with steel wool leaves tiny particles of steel behind. They may not even be visible. However, the small particles remain in the wood and when it rains they begin to oxidize and rust stains appear.
How do I clean a previously sealed deck?
Your entire patio should be cleaned once a year after sealing. Spot cleaning should be done as needed if something oily is spilled on your deck such as B. a fallen hamburger. Scrub your deck with a solution of regular liquid dish soap and warm water. Use a medium-bristle nylon scrub brush that doesn’t dig into the wood too much. Rinse with plenty of water until there is no more foam. Unless you have problem areas that have been left untreated for a long time, this cleaning method should suffice. If you have extensive stains, algae or mold on your patio, a stronger cleaner is required. Purchase a liquid deck cleaner and brightener at your local hardware store or home depot. This is more aggressive than soap and water but will not remove the existing sealant. The product is safe and easy to use, just follow the instructions.
How do I reseal my deck?
When it comes time to re-seal your patio it is very important that any previous seal is removed before a new seal is applied. This also applies if you use the same sealing brand. Sealer works by being absorbed into the wood. If old seal remains, absorption will be compromised. Sodium hydroxide based strippers will remove most old sealants. Be sure to follow the product instructions carefully. Soft woods like cedar and pine are the most susceptible to chemical damage from stains.
Some sealing marks are more difficult to remove than others. In our experience, Behr is one of the most difficult sealers to remove. It may be necessary to perform at least two cleanings before all of the old seal is removed.
How do you pressure wash without streaks?
Caked-on gunk comes off more easily if you first soak the surface, with or without detergent, and let it sit for a few minutes. When using detergent, wet from the bottom up, using sweeping horizontal strokes to prevent streaks caused by runoff.
Why You Should Never Pressure Wash Your Deck
But not all pressure washers are the same, nor are they suitable for all outdoor tasks. And it’s important to use this tool properly to ensure satisfying, damage-free results. Whether you’re in the market for a powerful, game-changing cleaner or already have one in your home care arsenal, make note of these best and worst practices so you can be sure to get the most out of this sleek, mean cleaning Machine.
Prepare before you start
Without an adequate water supply, your pressure washer will not meet your expectations for efficiency. First, test the flow of water from your hose by measuring the time it takes to fill a five-gallon bucket. If it takes two minutes or less, you’re good to go. longer than that indicates not enough water is flowing to run the washing machine. Once you have determined that your pressure washer is getting an adequate water supply, clean the inlet filter and check the connections are secure wherever the tool is on a hose or accessory such as a hose. Attached are tools such as Hyde’s rotating pintle nozzle wand, facilitating easy maneuvering during cleaning operations.

Don’t underestimate its power
A pressure washer’s greatest strengths – speed and power – make this tool as dangerous as it is efficient. Case in point: even the models with psi on the bottom have a jet of water powerful enough to cut through human skin! Protect yourself and property from harm by putting on safety goggles, gripping the wand firmly to avoid recoil when pressure sets in, and starting with the lowest pressure setting. Work with sweeping movements so that you never concentrate the tool’s power in one spot for too long – and always point the nozzle away from people, pets and your precious peony bush.
DO NOT use one nozzle tip for every job
You can equip a pressure washer with a variety of nozzles that create everything from wide spray patterns to narrow jets, so you can better use the water for the task at hand. Rule of thumb: The narrower the jet, the more power it unfolds. A wide 40 degree nozzle works well for general washing, e.g. B. for loosening dirt on redwood or cedar decking boards, cleaning side walls and rinsing garden furniture. A 25 degree nozzle tip tackles dirt and grime on concrete and other types of masonry. Zero or 15 degree nozzle tips focus intense pressure on a small area, making them most useful for removing stubborn iron stains.

Adjust the angle of your spray for the best power
When stubborn stains require maximum cleaning power, consider holding the pressure washer nozzle perpendicular to the dirty surface. Sounds easy enough, right? Well, it is – until you need to reach the underside of a patio table or the siding along the top of a house. Luckily, Hyde Tools’ problem-solving Pivot Nozzle Wand eliminates the need to bend or overstretch in those hard-to-reach places. Each of its models – the 18-inch wand for electric pressure washers and the 28-inch wand for the heavier, gas-powered machines – offers additional control via an adjustable nozzle. A simple twist of the handle rotates the spray at a 90-degree angle, allowing you to direct the power of your pressure washer’s stream over, under, or around any dirty object. No more squatting, stretching or straining to get the right spray angle.
Make your job easier
Too direct a jet can damage even surfaces you expect to hold up well to a wash, so always start with a light touch. Take siding, for example: pressure washers are great for cleaning most species, but if you stand too close you risk blowing off some of the paint or ruining softer woods like cedar. For best power washing results, stand 10 feet from the surface to be cleaned, turn on the water, then step forward until the jet is just powerful enough to dislodge dirt.
Don’t use a pressure washer on everything
Even with the utmost care and the slightest pressure, not all items are suitable for pressure washing, especially if they already show signs of wear. For example, while most car finishes can withstand heavy spray, a thin clear coat or a scratched exterior should be cleaned with less water pressure. To tackle these and other similar outdoor tasks, unplug the pressure washer from your garden hose and swap it for a HYDE PivotPro™ water wand, which features a detergent reservoir and an adjustable nozzle to save you from unnecessary strain and contortions. In addition, various PivotPro™ models are equipped with convenient, replaceable brushes that are attached to the front end. The Boat & Auto Kit includes a soft bristle brush, a reel brush for cleaning wheel rims and a microfiber pad to pamper your car’s exterior while removing dirt and road grime.

Master the right washing technique
Baked-on dirt comes off more easily if you first soak the surface with or without detergent and leave it to work for a few minutes. When using detergent, wet it from the bottom up and use horizontal wiping motions to avoid streaks from run-off. To rinse, do the reverse, working from top to bottom so you don’t miss a cleaner.

Should I sand my deck after pressure washing?
Make sure your deck is thoroughly dry before you sand. If there has been recent rainfall or if you have power washed, wait several days before sanding.
Why You Should Never Pressure Wash Your Deck
before you start
Follow any preparation steps recommended by the finishing product you intend to use. In some cases this may mean first using some type of chemical brightener/cleaner on wood that has grayed with age or wood soiled with dark tannins. This treatment with a brightener/cleaner is usually followed by rinsing with clear water; After the deck has dried, the fluffy wood fibers must be removed by sanding.
This treatment is most commonly recommended for aged cedar or redwood and may not be required for pressure treated pine or for new cedar or redwood. For new wood, the manufacturer sometimes recommends a simple sanding, followed by the immediate application of the stain or sealer.
The electric sanders used to sand a patio come in many forms, from standard household orbital sanders that are hand-operated to commercial rental upright sanders that you can rent from hardware stores and rental stores. Each of these, when used correctly, will sand your deck sufficiently. Most homeowners find it perfectly possible to sand with an ordinary hand sander, although patience is required, especially with a large patio that can require several days of work.
Keep in mind that woods used on decks are typically softwood species. Belt sanders, whether handheld or large stand models, tend to scratch softwoods, so an orbital or orbital sander is usually a better choice.
Make sure your deck is completely dry before sanding. If it has rained recently or if you have been power washed, wait a few days before grinding. Treat the deck surface, railings, and board edges as separate jobs, and vary the sanding techniques for each.
safety aspects
Be sure to wear a particle mask and safety goggles when sanding, as wood dust poses a health risk if you inhale it. Knee pads and hearing protection also make your work safer and more comfortable. Short-term exposure to wood dust is not likely to result in the cancer risk faced by industrial workers, but even short-term exposure can produce an allergic or respiratory reaction such as an asthma attack. The risk of reaction is particularly pronounced with red cedar dust.
Why has my decking gone white?
White spots can appear on water-based coatings when they come in to contact with moisture before they are fully cured. After a few days of sun exposure, the spots should dry out and fade, leaving no trace of anything but your handywork.
Why You Should Never Pressure Wash Your Deck
Don’t worry if you’ve just spent a few precious hours re-coating your deck only to notice white spots. The good news: It’s normal before a deck is fully cured. All the better: you can lean back and let the sun pamper you without lifting a finger.
White spots can appear on waterborne coatings if they come into contact with moisture before they are fully cured. After a few days of sun exposure, the stains should dry up and fade away, leaving nothing but your handwork.
If the stains haven’t faded after a few weeks and you want your deck looking picture-postcard, simply scrub with Cabot’s Deck Clean to remove any residue from rain or other water. When the deck is fully cured, the spots will no longer appear. Too simple.

Will power washing remove stain from deck?
Pressure washing is a quick way to remove a deck finish, but it requires some care so as not to damage the deck. A pressure setting of 1500 psi should be strong enough to clean away deck stain.
Why You Should Never Pressure Wash Your Deck
graffiti
Spray paint can be a major eyesore on the side of a building or structure. It can also be a real pain to try to remove. The good news is that you can remove graffiti from concrete surfaces with a pressure washer rated at 2000 PSI to 3000 PSI. Hold the nozzle about two feet from the painted surface and work in sections to drive it away.
For brick and metal surfaces we recommend using a chemical product like Smart Strip first to remove the paint. Apply as directed on the product label. Then use the pressure washer to remove paint residue and residue.
rubber
Chewing gum is one of the stickiest and toughest things to remove from any surface, including concrete driveways and other types of sidewalks. Pressure washers work wonders on those sticky gobs, even after you’ve been stuck there and stepping over them for a while. The trick is to use hot water while spraying on the gum to melt it away. If you’re using about 4000psi and working back and forth in a fan pattern, it should take off fairly quickly.
stains
With the addition of special pressure washer, this tool becomes a powerful stain remover. Cleaning solutions can help you remove stains from aluminum siding, wood and vinyl siding, driveways and sidewalks, decks, pavers, and other materials. You can even use the pressure washer to remove stains from the roof of your house. And the detergent blends work on all types of stains left by dirt, leaves and other plant matter, algae, accumulated dirt and more.
For stubborn stains, try pre-treating with the soapy water and a stiff brush. Also, consider choosing an eco-friendly cleaning product; It’s best to look for one that is water based and biodegradable.
colour
Peeling paint off a fence, siding, or brick surface can be hard work. Power washing makes it easier and faster. It’s always best to do a patch test before you begin to make sure the powerful spray won’t damage the surface being removed. Spray a small area, then adjust pressure as needed. Then work in sections and keep the sprayer moving to get the best result.
When pressure washing paint from a wood surface, be sure to spray with the grain of the wood. If paint thinners or strippers were used to remove the paint, be sure to pressure wash them thoroughly to ensure good paint adhesion when the new coat is applied.
rust
You can remove rust from metal with a pressure washer rated at at least 3000 PSI and a narrow-angle nozzle. The compact water jet is powerful enough to remove rust and saves you a lot of work when sanding and scraping. This is especially useful when cleaning old patio or patio furniture.
Mold & Mildew
Homeowners want to fight mold wherever it grows. It can do a lot of damage and ruin your home and health. Power washing is an effective way to remove mold and mildew from a variety of surfaces including glass, roofing, concrete, pavers, wood and siding.
By using a mold and mildew removal mixture such as B. Jomax concentrate, applied with a pressure washer, you can also remove the stains they leave behind. It works on aluminum and vinyl siding, driveways, decking and fences, brick, cement, stone and stucco.
cover stain
Power washing is a quick way to remove a topcoat, but it requires some care not to damage the deck. A pressure setting of 1500 psi should be strong enough to remove deck stains. Hold the sprayer about 3 inches from the surface and move the sprayer while working in the same direction as the grain. Learn more about deck maintenance.
Limescale and limescale deposits
Fountains, pools, and other hard surfaces can accumulate limescale and limescale over time. Hard water leaves behind these hard-to-remove mineral deposits. Limescale can be removed with a high-pressure cleaner.
Gutter Clogs
Homeowners hate cleaning their gutters; It’s really a tough, dirty job. Pressure washers can be fitted with curved attachments specially designed to make this job easier. The curved pole allows you to stand straight on your feet without having to reach up and down the gully. For single-story homes, power washing extensions can also eliminate the need for a ladder. The wand can help you clean the downspouts and prevent clogged gutters.
oil & fat
Cars and lawn equipment can leave unsightly oil and grease stains. But with power washing, homeowners can remove these stains from the garage, concrete driveway, and sidewalk. You will need a degreasing detergent and a pressure washer that delivers at least 1700 psi. For stubborn stains, use a high-pressure hose and pretreat the area by scrubbing with liquid dish soap and a brush.

How long should I wait to stain my deck after pressure washing?
Wood Deck Staining Overview
Let’s start by answering the question: how long should you wait for your deck to dry after you power wash it? The short answer is 48 hours. You should wait at least two days after pressure washing your deck before you consider staining it, to give time for it to dry.
Why You Should Never Pressure Wash Your Deck
Now let’s talk about details. Cleaning your deck is an extremely important first step in the staining process. If you were to stain your deck with dirt, the stain would seal the dirt onto the wood. Sealing the deck while it’s dirty allows dirt like mold and mildew stains to further gnaw at the wood, weakening your deck and it can create a dingy appearance.
Traditionally, deck sealing requires the following process:
Apply deck cleaner
Pressure wash to remove dirt and soap
Let the deck dry
Apply sealer or stain
Allow deck to dry for 24 to 48 hours
The whole process takes 3 to 5 days. Once the stain or sealer is dry your patio is ready to hang out and entertain again and should withstand all seasons for the next 3 years or so.
How often should a deck be power washed?
Frequency. Most home maintenance contractors recommend power washing your deck once a year. An annual wash will keep your deck in optimal condition, cutting down on accumulation of dirt, mildew, or algae growth.

Most home maintenance companies recommend washing your patio with a pressure washer once a year. Annual cleaning will keep your patio in top condition and reduce the build-up of dirt, mold or algae growth.
time of the year
It is recommended that you wash your patio as early as possible in the spring. When the weather gets warmer and you start thinking about getting those grills to grill, you want a clean, pleasant patio to enjoy. Why not clean your patio early in the season so you can enjoy it for the rest of the summer?
Power washing tips
If you decide to pressure wash your deck, there are a few things to keep in mind that can prevent potential damage to you and your deck. First off, pressure washers are great tools, but they can be dangerous. Improper use of pressure washers can result in personal injury as well as etching your deck. Be sure to carefully follow the instructions on the specific pressure washer you are using!
Before starting the power wash, apply an anti-mildew detergent and let it sit.
When you’re ready to begin, make sure you pick an inconspicuous corner to test. In general, most pressure washers should be set at 500-600psi, although some harder woods will require higher pressure. When you start using the pressure washer, keep the nozzle at least 30-45 cm away from the wood. You should use even strokes and go from one end of a board to the other. Work systematically so you don’t end up with a blotchy look.

Can you fix a hole in pressure washer hose?
A leak in a pressure washer hose can’t be fixed the way you would fix a garden hose. The patch won’t last; the high-pressure water will force the patch loose. Even a tiny patched leak can cause serious injury when it bursts open, and the high-pressure water hits your body.
Why You Should Never Pressure Wash Your Deck
You will then be given a choice. Would you like to dispose of your high-pressure cleaner and buy a new one? Do you want to repair the hose? Or do you want to buy a pressure washer replacement hose or a pressure washer hose repair kit?
Sometimes a pressure washer repair kit is the easiest
A leak in a pressure washer hose cannot be repaired the way you would repair a garden hose. The patch will not last; The high pressure water will loosen the patch. Even a tiny patched leak can cause serious injury if it ruptures and the high-pressure water hits your body. At the very least, you’ll get soaked and the laundry job you had planned for the day won’t get done.
The layers of wire mesh and plastic distribute the water evenly in the hose and hold the pressure. To repair the hose, each layer must be properly formed and repaired. If not, the repair will not last.
This isn’t the most difficult solution, but it’s not for everyone. Sometimes it’s best to just swap out the hose. There are many good replacement pressure washer hose kits available. They may end up saving you time. You can also take it to a professional to fix it. Look for pressure washer repairs near me for some options.
If you prefer to repair the high pressure hose, do the following.
Steps to repair your pressure washer hose
Switch off the high-pressure cleaner. If you are using an electric pressure washer, unplug it.
Squeeze the hose trigger to remove any water from the hose.
Find the leak and dry the area around the leak.
Make a square cut on each side of the leak.
Measure the diameter of the hose. You need this to find the right size of the compression fitting in the next step. Most home pressure washers are 0.25 inches, but check yours to be sure.
Create a compression seal with a Gates compression fitting. The female repair coupler is reverse-threaded and rotates counter-clockwise when fitted onto the hose. Use an adjustable wrench to tighten. The male repair coupler fits into the hose. Use engine oil to lubricate the tip. Place the hose in a vise or use two adjustable wrenches to connect and tighten the two pieces.
Next, connect the M22 adapter.
Finally, screw the M22 adapter onto the pressure washer.
Ensure the Gates compression fitting is the correct size for the outside and inside of the hose.

How do you release pressure from a pressure washer hose?
Once your pressure washer and water source are turned OFF and you are unable to disconnect your hoses from the pump and gun it is generally due to the pressure that is still inside of the machine. To relieve this pressure simply squeeze the trigger to release any water and then try disconnecting hoses again.
Why You Should Never Pressure Wash Your Deck
Taking care of your SIMPSON pressure washer and knowing how to troubleshoot your unit is an essential part of ownership. Extend the life of your pressure washer and protect your safety by following the tips below to avoid these common mistakes.
The important things first
Be sure to read your owner’s manual for all safety requirements, starting steps, and operating instructions before beginning the cleaning task.
1. My pressure washer will not start
After ONLY 30 days of downtime, the fuel in your gas pressure washer may be stale. It is important to always stabilize your fuel to prevent moisture from entering your fuel. Some people recommend that you drain your fuel and this is a good practice but still leaves your pressure washer vulnerable to moisture contamination in your tank and carburetor.
We recommend that you LEAVE your tank full and use the Ethanol Shield to prevent moisture contamination.
1 bottle (2 ounces) = good for 5 gallons of gasoline
Most SIMPSON pressure washer models have a 1/2 gallon tank. You need to pour 1/2 ounce. Ethanol Shield in your tank when the tank is FULL of gasoline.
By taking care of your engine, you extend its life and protect your investment.
2. My pressure washer pump seems to have failed after just one season
If you haven’t winterized your pressure washer, some residual moisture in your pump may expand in cooler months and cause tiny cracks in your pump. Hibernation prevents residual moisture from freezing, expanding, and potentially rupturing valves and seals in your pump.
After that, you’ll need Pump Guard for every season. Follow the instructions in your owner’s manual and read our How to Winterize Your Pressure Washer blog for helpful tips!
3. My pressure washer only delivers low pressure
Your SIMPSON may be operating at low pressure due to an incorrectly sized nozzle or a worn nozzle.
Always replace worn or broken nozzles as they can pose a potential safety hazard.
ALWAYS use accessories that are within the PSI range of your pressure washer. You could lose pressure as your accessory is rated for a higher/lower PSI range than your machine and may damage your accessory.
Be sure to check that the water is turned on all the way and that enough water is flowing through the pump. Check your pump’s inlet filter to make sure there is no debris blocking the water flow. A vertical hose or hose that is too long can delay the rapid arrival of water pressure.
4. My high-pressure cleaner runs very erratically
You may need to check your air filter to make sure it’s free of debris. If dirty, clean or replace if possible.
You can also check your spark plug for wear or fouling, clean or replace if possible.
If it’s been a while since you used your pressure washer and you haven’t used Ethanol Shield, your fuel may be contaminated. This preventive maintenance formula eliminates and then prevents ethanol-related problems. It removes water, prevents corrosion, allows easy engine starting all year round and keeps stored fuel fresh.
If your engine is still rough, you may need to contact your engine manufacturer to locate the nearest authorized engine service center.
5. My pressure washer pump is leaking water
If your pump is losing water, it can be caused by:
If you run your pressure washer for more than 2 minutes at a time, it will go into bypass mode. This means that the water in the pump is continuously flowing and heating up. If your pump is too hot, it will cause damage and possibly rupture. To prevent the pump from overheating, your SIMPSON is equipped with an overheat valve (safety feature only) that will release hot water if the pump gets too hot.
Make sure to turn off your device when taking breaks longer than 2-3 minutes.
If your pressure washer is leaking at the gun, wand or nozzle, it could mean that your accessory is not attached securely enough. Turn off your machine and make sure everything is properly tightened.
6. My pressure washer just shuts off during use
SIMPSON pressure washers are designed to ensure you don’t damage the engine or other mechanical components. Generally, the reason your SIMPSON pressure washer has just shut down is that it is out of petrol or oil.
ALWAYS check the oil and gas levels in your pressure washer when you are about to turn it on.
7. I cannot disconnect my high pressure hose and garden hose from the pump
Generally, once your pressure washer and water source are off and you can’t disconnect your hoses from the pump and gun, it’s because of the pressure that’s still inside the machine. To relieve this pressure, simply squeeze the trigger to release water and then try disconnecting the hoses again.
8. My pressure washer isn’t pulling soap
Always make sure your low pressure soap nozzle is inserted into your wand. If you have high pressure nozzles attached to the wand, your pressure washer will not suck up soap.
9. Am I using the right chemical for my pressure washer?
Always use a soap suitable for high-pressure cleaners when cleaning. NEVER use bleach or other harsh chemicals as this can damage your pump and cause it to fail.
There are different soaps that are specifically designed for your cleaning task. When power washing sidewalls, be sure to check the label on your soap to determine if it’s safe. Always test a small area of your surface before applying soap to the entire surface to avoid damage.
10. I can’t reach the second floor of my house
Although your pressure washer is extremely powerful, it may not be enough to reach your second floor.
NEVER use a ladder when power washing as this is extremely unsafe and not an effective cleaning method.
Instead, you should invest in a second nozzle accessory to reach those high areas.
SIMPSON second floor nozzles come in a pack with one high pressure and one low pressure soap and dish soap nozzle.

Can you ruin concrete with a pressure washer?
The quick answer is yes, power washing can degrade a concrete surface. You can notice visible damage from water pressure at the level at which even light-duty power washers can operate. Therefore, if you aren’t careful, you can cause irreversible damage to your driveway or patio.
Why You Should Never Pressure Wash Your Deck
The quick answer is yes, power washing can damage a concrete surface.
You can see visible damage from water pressure at levels even light pressure washers can handle. So if you’re not careful, you can cause irreversible damage to your driveway or patio. Some concretes are also weaker than others, making some areas more prone to forming lines, pitting or other surface imperfections, not to mention deteriorating joints if mortar or joint sand is washed away during the process.
The main causes of damage from high-pressure cleaning are using the wrong nozzle, too high a pressure, spraying too close to a concrete surface, and holding the nozzle in one spot for too long. Of course, as with any device you buy for use on your property, you should read all of the instructions thoroughly before you begin.
Now let’s dive deeper into how you can give your concrete surfaces an upgrade without accidentally causing other problems.
How to wash concrete with high pressure
When done right, concrete pressure washing can have a patio, driveway or sidewalk looking as good as new in as little as a day. For the sake of this post, you should know that we do not differentiate between power washing and high-pressure washing.
If you have decided to pressure wash your surfaces yourself, you will need to buy, rent or borrow a pressure washer. For many homeowners who only pressure wash once a year, renting a pressure washer makes more sense than finding space to store a pressure washer for the rest of the year and also avoiding the hassle of doing maintenance or repairs.
Depending on the size of the area you want to work on, you should probably plan to spend most of an afternoon or morning getting the job done. Pressure washing can be a very messy job, so wear shoes you don’t mind getting ruined and pants to protect your legs from rocks or loose materials that your pressure washer could throw off. Keep in mind that you may start pressure washing in one area and decide that you need to pressure wash every surface on your property. Yes, it can be so addictive!
If this is your first time using a pressure washer or if you have never got around to it, read the instructions first. If you’re hesitant or find you just don’t have the time or interest to do it yourself, consult a professional. Someone who power washes daily knows exactly how to clean your surfaces without damaging them.
Now let’s go through all the steps required to power wash a surface.
Check your water supply
Without an adequate water supply, your pressure washer cannot do its job efficiently. To make sure you have adequate water flow, you can do a quick test by seeing how fast your hose can fill a five-gallon bucket. If it takes two minutes or less, you’re good to go.
Check your nozzle
It can be tempting to use a small nozzle, but the wrong size can damage many surfaces. The higher the number, the less narrow and powerful the beam. For most concrete and other masonry jobs, stick to a 25-degree nozzle to spray and rinse your surfaces. You may want to use a finer nozzle to remove grease stains. A 15 degree nozzle should only be used for materials like iron that can withstand even the most intense pressure from your washing machine. Never use a 0 degree nozzle as it is a safety hazard.
If you’re not sure which nozzle to use, try the widest size first and work your way down. Even the 25 degree jet is a bit too intense for trim, furniture and more delicate decks. Only use a smaller nozzle on concrete when applying detergent for a deeper clean.
Rate the area
Look at the surfaces surrounding the concrete you want to wash. Sure, the concrete can withstand the pressure you’ll unleash, but what about the windows nearby? The garden furniture? The wooden terrace?
Cover all sensitive areas before you start pressure washing. Also remove your car if you pressure wash in the driveway. If you lose control and the washing machine blows up your car, you may end up with chipped paint. Also, check any tripping hazards that might be nearby. Nobody wants to trip over a pressure washer and lose control. Remove toys from the lawn or long cords that could become dangerous when you are about to start washing.
To back up
When you’re ready to start washing, take a few steps back. Remember that an explosion from too close a distance can damage the surfaces to be cleaned. Start cleaning by standing at least 10 feet away from the area you want to hit with water. Once the pressure washer starts running, feel free to move a little closer until you are comfortable with the distance from your surface.
Aim high and keep it moving
Once you’re ready to wash, aim for an angle higher than what you want to hit. Turn on the washer to spray at 3,000psi and adjust your stance accordingly. Applying more pressure can be risky, especially if your concrete is not in good condition. Keep the nozzle pointed in one direction while washing. This will prevent etching and other damage to the surface you are washing on. We recommend that when cleaning your concrete with detergent, you work your way up from the bottom of your surface. When flushing, start at the top and work your way down.
If you’ve never done Power Washed before, you should know that there’s a learning curve and you can’t really rush the process. You will probably want to start with a less visible area until you understand how your pressure washer works. For consistent results, you must maintain a constant distance from your surface. If you start pressure washing farther away and then get closer, some parts of your driveway will look darker than others. You may want to focus on one area at a time. Power washing can get tiring, so you’ll likely need to take breaks, especially if you’re working on a large area.
While you will do everything in your power to be careful when using your pressure washer, things can still go wrong. What can go wrong with high-pressure cleaning?
Damage from power washing
Although concrete is among the strongest building materials available, it is not immune to wear and tear. Cracks, chips, and bumps can develop over time, especially on driveways that see a lot of foot and car traffic. A pressure washer delivers 30 to 80 times more powerful water than your garden hose.
You know you’ve damaged your concrete due to poor pressure washing when it looks etched, creating an uneven surface and an unattractive driveway or finish. However, etching and other types of concrete damage are not always due to extreme pressure and could have been present before you removed the layer of dirt that was on a surface.
If you have recently laid concrete, you should temporarily refrain from washing with pressure washers. Concrete takes at least a year to bond enough to withstand this kind of pressure. If you need to clean concrete without as much pressure, you can try mixing water with dish soap and scrubbing the stain or discoloration yourself.
Another type of concrete damage we encounter is when homeowners electricity wash their concrete too frequently. Concrete should be cleaned annually with a high-pressure cleaner. So if you pressure washer your concrete once a month (or even more frequently), it’s more likely to wear down and become damaged.
Keep in mind that if you’re transitioning from pressure washing your concrete to another type of surface, such as a tile, you’ll probably want to reduce the pressure. B. change your garden furniture. Wooden decks can benefit from a pressure wash, but some can be cleaned with a garden hose. Pressure washing the roof is generally a bad idea, as turning on the machine while standing on a ladder can throw you off balance. Shingles can also be removed with a pressure washer. It’s also generally a bad idea to pressure wash your car as it can damage your paintwork. Even contact with your skin from a high-pressure jet can cause cuts and bruises, and eye injuries can send you to the hospital.
There are also some homeowners who don’t necessarily have etches on their concrete, but there are marks from the pressure washing – so what can you do about it?
How to remove Power Washer marks
Don’t worry if you leave marks on your concrete. Residual traces are much easier to deal with than etching or actual damage.
Take a look at the concrete surface you just electricity washed. You may see some leftover debris or pieces that didn’t make it off the surface. If you can rely on your power washing skills, you can go over the concrete with a much wider nozzle. Or you can simply brush it off or use a gentle spray to remove the residue. Usually these marks come from rushing through the job. If you start seeing stains while pressure washing, slow down a bit and make sure you go through each section thoroughly before moving on to the next area.
While most homeowners will just blast water in a high-pressure jet to remove stains on a surface, you can also try using a detergent to remove stains or discoloration. If you go this route, consider using a smaller nozzle when applying cleaning products. The detergent you buy should come with more detailed instructions on how to use the product. If you follow these instructions, you should get the best results with minimal pressure washer marks.
Sometimes stains don’t come from the pressure washer itself, but from oil, grease or more stubborn deposits. In these cases you can experiment with a different nozzle or get a little closer to see if higher pressure removes the marks. If the pressure washer’s markings are making you nervous about picking up the nozzle again, it’s time to call in a professional.
Additional power washing tips
What else should you consider before you start high-pressure cleaning your concrete?
Do your homework
No matter the size of your job or how long you’ll be using the pressure washer, you should take precautions. All that power can make a lot of noise, so do your research before renting or buying a pressure washer. Some models make more noise than others, which can be a consideration if you don’t want to disturb your neighbors.
In addition to wearing appropriate clothing, safety experts recommend protecting your ears with earmuffs or headphones, even if you use a safer or smaller model. Additionally, wearing gloves, goggles, and long-sleeved clothing can prevent exposed skin from feeling the pressure. Try to sweep the area you want to power clean so you don’t risk hitting yourself or anyone nearby with rocks or other debris. Never point the nozzle at a person to avoid possible injury.
Be careful with the environment
Pressure washing may be prohibited if your area is affected by a drought. Even without these limitations, it is important to think about the environment and water wastage. If you follow our tips on how to properly pressure washer your home or property, you shouldn’t have to waste water, but be careful how much you use.
Power washing can be more than just water.
Take a look at the ingredients in all the cleaning products you use with your pressure washer. Are they eco friendly? Can they do any harm if they land on your lawn or in the sewers? Here are some ingredients you might want to avoid:
hydrofluoric acid
hydrochloric acid
sodium hydroxide
bleaching
Turn to the professionals
Homeowners who wash their concrete can often cause accidental damage, either to their home or to themselves. In addition to damaging concrete, power washing horror stories include removing paint from homes, ripping off sidewalls and clapboards, damaging wooden decks , destroying car paintwork and even causing serious injuries.

Why You Should Never Pressure Wash Your Deck
Concrete cleaning with a surface cleaner versus a traditional wand
A professional concrete cleaning company often uses a surface cleaner to clean concrete in residential and commercial properties. What is a surface cleaner? A surface cleaner is a tool that has a rotating spray bar with a high-pressure hose attached to it. They come in a variety of shapes and sizes. The spray bar has two or more angled nozzles that provide the impetus that rotates the bar. The high-pressure jet emerges from the nozzles while the spray bar rotates.
A surface cleaner is superior to a stick in many ways. Here are just a few of the benefits of using a heavy duty cleaner to clean concrete.
Spray nozzles are ALWAYS about 1 inch from the concrete, allowing for an even cleaning pattern. With a magic wand, the spacing varies, resulting in uneven and often unsightly lines.
Speed! Imagine being able to clean a 28 inch path in one go. Using a surface cleaner can clean most residential driveways 50-75% faster than using a magic wand.
Water usage is a big factor in a surface cleaner. The increase in speed also means less water is used, which is better for the environment and saves on water bills.
Holding a wand too close can etch concrete. Etched concrete is generally not repairable. Using a surface cleaner greatly reduces the risk of operator error that can easily damage a concrete surface.
The only downside to surface cleaning is that you must have professional equipment to run it. A minimum of 4 gallons per minute and 2500 PSI is required for a surface cleaner to function properly. Most homeowner pressure washers are unable to properly run a surface cleaner due to the size of the motor and pump.
PRO WASH, LLC has several large and small surface cleaners. Small, tight spaces are usually best suited for a 16″ version, while large parking lots or long sidewalks are cleaned much more efficiently with larger diameter versions. For larger projects we usually run 2 28″ models at the same time. We offer free advice and estimates. Call or email us if you have any questions about your concrete cleaning project.
Does Power Washing cause mold?
The power of the washer can break the seals around windows, damage window screens, and shatter glass, especially with a narrow tip at a high-pressure setting. Plus, if any water breaks the seal around the window and seeps into the wall, it could lead to mold and rot indoors.

How To Remove Pressure Washer Marks From Deck? 2 Best Ways!
How do I remove pressure washer marks from the deck? It includes two ways of oxygenating energy for wooden decks and using hydrochloric acid for concrete decks. Either one can make the cleaning task easier provided you prepare the right equipment. Also, research cleaning tips that will help you with that.
Cleaning your patio with a pressure washer is a lot indeed. The pressure washer can help save time, money and effort.
But the pressure washer marks only ruin the overall look of your decks. So avoid this stressful and frustrating experience of seeing markers in your decks. Instead, fix this problem by following the methods below. There is so much more to learn, so it’s best to keep reading this article!
Pressure washer A great investment
Many homeowners have found pressure washers to be a significant investment, and they have become one of the most well-known methods for removing stains and stubborn stains. However, not everyone is aware that this cleaning machine has several types. Without sufficient knowledge about the types of pressure washers, pressure washer marks can appear on decks. However, there is no need to hire a professional cleaner to remove water pressure marks as the methods below are effective in removing pressure washer marks and restoring them to their good looks.
Ways to remove pressure washer marks from the deck
So how do you remove pressure washer marks from your deck? Here are the two known ways to remove pressure washer marks from the deck:
#1. Oxygen power for wooden terraces
If you have wood decks with pressure washer marks, you can use this method to beautify them and remove marks. First, let the oxygenating power act on the wooden surface of the deck for 2 to 3 hours. Then rinse it properly. Proper flushing on deck follows a technique. When rinsing, use the jet to lower the pressure to 800psi. However, if you don’t have another nozzle, hold the tip of your spray wand 13 to 17 inches from the surface to relieve pressure and allow the water to hit the surface better.
Start flushing it out to drain water off a wooden deck. Slowly bring the stick spray into one position before rinsing. Start at the end point of the board and slowly work your way to the end point while keeping or holding the nozzle at an actual distance. Rinsing off the surface will prevent the wood deck surface from staining. Also, there are times when you need to stop while you are in the middle of the surface or board. In this case, you must restart the process on the other side of the board until you reach the spot again.

#2 Use muriatic acid for concrete decks
Using pressure washers is the most manageable and stressful way of cleaning dust, dirt, stains and debris from a concrete patio. But if you’re careless, deep marks can appear on your concrete deck. Having those tiger tracks on concrete decks can be frustrating. But don’t stress yourself so much because there is something you can do to remove pressure washer marks with muriatic acid spray on the concrete pavement. This process is also known as acid etching while others refer to it as an acid wash technique.
Before applying some muriatic acid, brush, sweep and vacuum first to remove dirt and dust from the cement. Next, properly dissolve the hydrochloric acid in a container of water. Boil enough water and then gradually add some acid. The mixture must be 1 part acid and 4 parts water. Carefully pour the hydrochloric acid onto the surface and leave it on for at least 5 minutes. After applying a muriatic acid, then scrub it. Add some garden lime, baking soda, and ammonia to the water while scrubbing the surface.
Never let the concrete surface dry when pouring the acid. Then rinse it properly with your pressure washer with a suitable flat jet nozzle. After rubbing and cleaning, hose down with tons of water. It is not recommended to use a pressure washer to rinse the acid off the surface as it will only remove the acid deep within the cement. Take precautions as hydrochloric acid can be dangerous. This method is only useful for outdoor concrete decks.
Here’s what you should know when cleaning your concrete deck.
Safety tips to keep in mind
Always observe precautions such as wearing a protective mask, safety goggles, gloves and chemical-resistant clothing when removing pressure washer marks on wood or concrete decks, especially when using detergents and cleaning acids. Also, read the instruction manual carefully before using your pressure washer. Do’s and don’ts are usually included in the manual. Also, learn about the machine and master how to use it according to the interface. This way you avoid some damage. When the water pressure marks appear, you can not worry and frustration as you know how to fix them.
It’s a wrap!
Now you will learn how to remove pressure washer marks from decks using the two well-known methods of using muriatic acid and deck oxygenation. Nevertheless, proper training, experience and knowledge of how to use a pressure washer is a prerequisite to fully optimize the machine’s capacity. At the same time, you ensure that there are no ugly high-pressure cleaner marks afterwards. Otherwise it will ruin the look of the wooden or concrete decks.
How to Fix Pressure Washer Marks in Cement
A pressure washer is a handy device that can serve multiple purposes for homeowners. From washing your driveway or car to debarking logs to repairing pressure washer marks in cement, pressure washers will do the job for you. In this blog post I will discuss a method to repair pressure washer marks in cement.
To fix pressure washer marks in cement, try spraying on some hydrochloric acid and scrubbing quickly. Then high-pressure wash with a fan nozzle. A hydrochloric acid solution etches the cement and camouflages the tracks.
When your driveway’s cement surface accumulates antifreeze stains, dust, dirt, debris, dry twigs, rubber, dirt, grease, spilled drinks, mold, mildew, mud, oil, and pet urine, it becomes an unpleasant experience. It is necessary to wash it under pressure. When a beginner uses a pressure washer, he/she can leave deep marks in the cement as the top layer of cement is washed away as well.
“You may be inclined to pressure wash almost everything in your home, but it’s not always a good idea,” said Dave Trezza, the test engineer who oversees pressure washer testing for Consumer Reports. “The charged jet of water can damage paintwork and nick or etch wood and even certain types of stone.”
Fortunately, there is an effective way to fix tiger stripe marks left in cement by a pressure washer. For these brands, muriatic acid is the solution. Hydrochloric acid is also known as hydrochloric acid.
How to wash cement with acid?
Acid washing is also referred to as acid etching. To fix traces of pressure washer in cement, brush or vacuum dust from cement. Remove the oil stains with an alkaline cleaner or degreaser.
However, do not use TSP (Trisodium Phosphate) cleaner. It can react violently with hydrochloric acid and release noxious gases. Rinse the cement with water.
It is better to use muriatic acid or muriatic acid (a less pure variant of hydrochloric acid), but remember that these products are very dangerous as they produce toxic fumes. It can only be used outdoors. You must take the necessary safety precautions before planning to fix the markers in cement.
You can find hydrochloric acid here. If you are not comfortable with these products, you can also ask a professional.
Use a pair of acid-resistant gloves, a pair of rubber boots, an acid-filtering respirator, a face shield, a butyl or PVC apron, and vapor-tight goggles. Make sure the area you are cleaning is ventilated to ensure adequate ventilation. Keep some baking soda or garden lime at arm’s length to neutralize unnecessary spills.
Always use a plastic bucket or watering can to dilute the muriatic acid. Pour the water first and then slowly add the acid. Unlike metals, most plastics are resistant to the damage caused by hydrochloric acid.
Mix three to four parts water to one part acid for a ten to fifteen percent concentration. Moisten the entire area. Spray the water onto the cement until it is completely damp but not puddled.
Remember that one gallon of muriatic acid can repair up to 45 square feet of pressure washer marks. Immediately after pouring the acid solution, brush the cement with a long mason’s brush or a push brush. Be careful not to let the cement dry out as you pour the acid.
Keep the garden hose handy. Wait at least ten minutes for the hydrochloric acid solution to completely etch the cement. Scrub away any residue with a large brush before the acid dries. Rinse with plenty of water.
Add a cup of ammonia, baking soda, and garden lime to a gallon of water. Scrub it over your cement, especially in the corners, and let it sit for at least 10 minutes. Any liquid left on the surface of your cement will leave white marks after it dries.
Spray the cement with plenty of water and repeat several times. Finally, rinse off the water with a brush or vacuum cleaner and hose. Never use a pressure washer to rinse off the acid as this will drive the acid deep into the cement.
Use a pH test strip to check the last rinse water. If the result is below six, it means there is a lot of acid left on the cement, but if the result is above nine, it means there is a lot of basic neutralizers. Rinse again. Here you will find pH test strips.
Never save the leftover hydrochloric acid solution for later use. Pour into a plastic bucket that is slowly being filled halfway with a base neutralizing solution. Now slowly add more acid and base until the solution stops bubbling.
After this mixture is completely neutralized, pour it down the drain or sink. Dispose of the remaining acid in the same way. Stored hydrochloric acid is a serious hazard.
Frequently Asked Questions (FAQs):
● What is a commercial pressure washer?
Commercial high-pressure washing uses high-pressure water spray to remove algae, dust, dirt, grime, grease, chewing gum, fungus, sludge, mildew, and loose paint. A commercial pressure washer is an automated tool consisting of two or four high-pressure nozzles on a rotating rod that rotates as the water flows. This action creates a uniform cleaning pattern that can clean flat or curved surfaces at high speed.
Regular use of a high-pressure cleaner reduces allergy pathogens, asthma pathogens and bacteria and improves the aesthetics. It is suitable for indoor and outdoor use in areas such as aisle, loft, balcony, siding, driveway, patio, gutter, fence, roof, patio, sidewalk, lawn or parking lot. You can find a professional high-pressure cleaner here.
● Can I high pressure clean my roof?
No, do not pressure wash your roof as it is very dangerous and potentially harmful. If you’re a beginner, using a pressure washer will cause recoil that will throw you off the ladder while you’re on it. The strong jet of water loosens the asphalt shingles on your roof.
It strips the embedded granules, which extends the life of the roof. It’s safe to spray on a cleaner that kills moss and mold. You can also use a pump sprayer filled with a mixture of bleach and water to kill the moss on its own.
First build up the pressure in the pump sprayer, then climb the ladder. Make sure your roof gets maximum sun exposure as this will discourage moss growth.
● Is it safe to pressure wash a wooden deck?
Yes, a wooden deck can withstand the pressure well. Camaru, Ipe, Tigerwood, Yellow Pine and other South American hardwoods can withstand the pressure well. As long as you don’t hold the nozzle too close, the pressure-treated wood decks are fine.
To ensure the spray does not mark or etch the wood, always start with a low pressure nozzle. Always work along the length of your board to match the grain of the wood. Read your owner’s manual to learn the manufacturer’s recommendations for the distance you need to maintain between your nozzle and the surface of your deck, and learn more about nozzle settings.
● Is it safe to pressure wash the cement driveway or sidewalk?
No, cement cannot withstand high-pressure cleaning. Only a lower pressure nozzle is safe for moldy or mold covered cement. However, never use a zero degree tip as it will leave deep visible marks in the cement of your driveway or sidewalk. You can find tips on high-pressure cleaner nozzles here.
● Is it safe to pressure wash a siding?
Sometimes a vinyl siding can withstand a high pressure wash and a cement siding cannot. An aluminum panel dents during high-pressure washing. Wood clapboard siding can withstand high pressure washing.
Always start with the lowest pressure setting with a wide nozzle. You can only use more concentrated blasting media for stubborn stains. Never pressure wash clapboard siding as the clapboards will be knocked off.
When pressure cleaning your trim, avoid trapping water between the trim and the trim as this encourages mold growth. Never let water get into the open gaps of sidings. Replace or repair the damaged, loose, or missing sidewall prior to pressure washing.
● How many types of nozzle tips are there in a pressure washer?
Pressure washers come with either an all-in-one variable spray wand that lets you adjust the water pressure with a twist, or a set of interchangeable nozzles.
Five different nozzles include:
The red jet is the strongest, most concentrated jet setting. The yellow nozzle is used for heavy duty cleaning. The green nozzle is for general cleaning. The white nozzle is used for vehicles, patio furniture, boats and easily damaged surfaces. The black nozzle is a low-pressure nozzle for applying soap and other cleaning products.
You can find tips on high-pressure cleaner nozzles here.
Closing remarks
To conclude this answer post, I would like to say that you can use muriatic acid or muriatic acid to fix the pressure washer marks in cement. Make sure you follow all the necessary safety precautions and use it outdoors to avoid inhaling the noxious fumes it gives off. Always seek the help of professionals to pressure clean your cement surface.
Proper training and experience are required to operate a pressure washer. Otherwise you will severely damage your cement or concrete surfaces.
Why You Should Never Pressure Wash Your Deck
This year you may have enjoyed more time on your patio. Soaking up the sun in your yard was good therapy and a relaxing way to spend a summer day.
However, as the season progressed, you noticed more details: The leaves building up in the corner. The tannin stains that have bloomed around your planters. The colorful punch left by a child. The mold that grows where your gutter leaks.
You are ready to clean every corner of your deck and get ready for a new season. You may also want to apply a fresh coat of sealer or top stain. Either way, you’re ready to restore its shine. Should pressure washing be part of your deck cleaning routine?
Watch out for damage from high-pressure cleaning
Using a pressure washer seems like a quick and easy way to get rid of the accumulated dirt and grime. However, you must be aware of the damage it can cause. If you have wooden decking, the pressure of a pressure washer can cause chips and damage to the wood fibers. If the wood surface has already chipped a bit, pressure washing will only make the problem worse.
You may have heard about the problems of pressure washing a wooden deck. But what about composite decking? Depending on the material, a high-pressure cleaner can also scratch boards if the pressure is too high. If the power wash gets too intense, it can even chip the material.
Damaging your composite deck with a powerful pressure washer can void the warranty. Damage caused by the use of high-pressure washing is usually not covered, so you would have to pay for your repair.
If you’ve installed quality composite decking like Trex, you should wash it every six months (spring and fall are best for the weather). Trex recommends a basic cleaning with a composite deck cleaner or a combination of soap, hot water, and a soft-bristled brush. Note: Using products containing bleach or acid will lighten the finish of Trex.
Is it ever okay to power wash a deck?
The biggest problem with powerwashing is the pressure. You may be able to use a low pressure setting to aid in your cleaning. However, it is recommended to leave this to the professionals.
If you are doing this project yourself:
Keep the pressure washer at least two feet off the ground.
Use a pressure washer with a fan tip attachment/adjustment and soap dispenser to remove dirt, concrete dust, or other types of debris.
Spray the deck with soap and then gently scrub each deck board with a soft brush.
Rinse thoroughly. If dirty cleaning water is left to dry, it will leave a film on the decking surface.
When hiring a professional, be sure to ask for someone with decking experience and suggest using a relatively low pressure setting (typically set the spray pressure to 1,500 PSI or less).
Cleaning without a high-pressure cleaner
The safest way to clean your deck is with soap and water. For the basic cleaning of the deck you will need:
A broom
A garden hose
A bristle brush
A biodegradable deck cleaning solution (dish soap can work well); Avoid bleach and acid solutions unless you have tested them on a small area that is not easily visible
Here’s a simple step-by-step guide to cleaning without a pressure washer:
Remove furniture and other items from decking. Sweep any leaves or other debris off your deck. Test your cleaner on a small area to make sure there are no stains. Clean with water, a cleaning solution and a bristle brush. Scrub the entire deck. Rinse with a hose. Make sure it’s rinsed out completely so it doesn’t leave a film. Allow the patio to dry completely before putting furniture and decorations back on the patio.
Cleaning by situation: Not every cleaning situation is the same. Trex offers the following tips for cleaning your composite deck, depending on your particular challenge.
For dirt and debris: The affected area should be hosed down to remove surface debris. Use warm, soapy water and a soft-bristled brush to remove dirt and debris from the embossing pattern.
Tannin-Related Deposits: Remove any deposits from the deck with a hose or broom. Once the deck surface is dry, apply a “deck lightener” to the deck as directed by the manufacturer. Decklighteners contain oxalic acid, which removes tannins.
Chalk Lines: Highly permanent chalk lines can discolor the surface. Use only Irwin Strait-Line® Dust-Off Marker Chalk (purple), available at www.Irwin.com.
Oil and Grease: Clean up any spilled food as soon as possible. The surface must be cleaned within seven days to maintain the stain guarantee. To remove, hose down and use warm, soapy water and a soft-bristled brush to remove spatter from the embossing pattern.
Mold and Mildew: When debris such as pollen and soil is left on the deck surface, mold can feed on the biofilm. It is recommended to use a hose and warm soapy water with a soft bristle brush to remove the food source and mold.
When your deck has reached the point of no return—it’s beyond stripping, sanding, restaining, and repairing—make plans for a new deck. To protect your deck any time of the year, be sure to use flashing tape like Trex Protect. With its superior waterproofing power and deck cleaning skills, you can enjoy an outdoor living space for years!
