Pressure Washing Composite Decking – Is It Safe?
What Is Pressure Washing Composite Decking?
Pressure washing composite decking is a popular cleaning method and maintaining outdoor living spaces.
The composite decking material is tough and low-maintenance to withstand outdoor elements. Even though it is durable, it still requires regular cleaning to keep it looking its best.
It also means cleaning the surface of your decking with high-pressure water to remove dirt, grime, and other debris.
When done correctly, pressure washing can remove stubborn stains without damaging the decking material.
Is It Safe To Pressure Wash Composite Decking, Or Is It Bad?
If you own a composite decking, you might wonder if pressure washing is safe for your investment. After all, you don’t want to cause any damage to the surface or void the warranty.
The good news is that deck pressure washing can safely and effectively clean your composite decking. If and only if with the right equipment and technique.
Here’s what you need to know:
Use the right pressure washer.
Not all pressure washers are created equal. That’s why using the wrong one can damage your composite decking.
Look for a pressure washer with a PSI (pounds per square inch) rating of no more than 1500. Use a wide-angle nozzle to avoid causing any damage to the surface.
NOTE: Higher PSI pressure washers can damage the surface and even void the warranty.
Choose the right cleaning solution.
While water alone can remove dirt and grime from your composite decking, a specialized cleaning solution can make the job easier and more effective.
However, not all cleaning solutions are suitable for composite decking. Follow the manufacturer’s instructions to look for a cleaning solution specifically designed for composite decking.
Be careful with the pressure.
When pressure washing your composite decking, using the right technique is important to avoid damaging the surface.
Hold the nozzle at a slight angle, and work in small sections to cover the entire surface evenly. Use a sweeping motion, and keep the nozzle at a consistent distance from the surface to avoid leaving marks or streaks.
Test a small area first.
If you’re unsure if pressure washing is safe for your composite decking, test a small and inconspicuous area first.
This will help determine if the pressure and cleaning solution suits your decking and avoids potential damage.
In conclusion, pressure washing can be safe for your composite decking using the right equipment and technique. It can be beneficial because it will only require less maintenance after pressure washing cleaning.
Test a small area on your deck’s surface first, and avoid using high PSI pressure washers.
How To Pressure Wash Composite Decks
Pressure washing your composite deck is a great way to keep it looking clean and new. Composite decking is a low-maintenance option resistant to rot, mold, and insects.
However, dirt and grime can still accumulate on its surface, making it look dull and dingy. To pressure wash your composite deck, follow these steps:
Prep the area
Before you start pressure washing, clear the deck of any furniture or other items that might get in the way. Cover nearby plants with plastic sheeting to protect them from the force of the water—clean decking to make the pressure cleaning smooth.
Choose the right pressure washer
Not all pressure washers are created equal. Make sure you choose a model designed for decks with no more than 1500 psi pressure. Higher pressure can damage the surface of your composite decking.
Use the right nozzle
Most pressure washers come with a selection of nozzles for different tasks. Choose a 25- to 40-degree nozzle for cleaning your composite deck. This will provide enough force to remove dirt and grime without damaging the surface.
Apply a cleaning solution
Several cleaning solutions are available specifically for use on composite decks. Follow the manufacturer’s instructions for mixing the solution and apply it using a pump sprayer to your deck. Correct deck cleaner solution makes the difference during and after the process.
Begin pressure washing your deck, starting at one end and working across the surface in small sections. Keep the nozzle at a consistent distance from the deck and move it in a sweeping motion to avoid leaving marks.
Once you’ve pressure washed the entire deck, rinse it thoroughly with clean water. This will remove any remaining dirt and grime, as well as any cleaning solution.
Allow it to dry
Let your composite deck surface dry completely before replacing any furniture or items you removed earlier.
What PSI Can You Use on Your Composite Decking?
You may be wondering what PSI you can safely use when pressure washing it. Pressure washing is a great way to keep your composite decking clean and looking new.
NOTE: Too high pressure can damage the deck surface and ruin its appearance.
So, what PSI can you use on your composite decking? Generally speaking, you should use a pressure washer with a PSI (pounds per square inch) of no more than 1500.
NOTE: Higher PSI can damage the surface of the decking and cause splintering or cracking.
It’s important to note that not all composite decking is the same. Some manufacturers may have specific recommendations for pressure washing.
Always check the manufacturer’s instructions before washing your composite decking to ensure you use the correct PSI. Additionally, using the right nozzle when pressure washing your composite decking is important.
A 25- to the 40-degree nozzle is recommended for cleaning composite decking, as it provides enough force to remove dirt and grime without causing damage.

Can Pressure Washing Your Composite Decking Cause Damage?
The answer is yes.
Pressure washing can cause damage to your composite decking if it’s not done correctly. Here are some of the potential risks and how to avoid them:
Scratching the surface
Composite decking is designed to be durable and scratch-resistant, but it’s not scratch-proof. Using a pressure washer with a high PSI rating or holding the nozzle too close to the surface can cause scratches and marks that can be difficult to remove.
How to avoid: Use a pressure washer with a low PSI rating and a wide-angle nozzle, and hold it safe from the surface.
Fading the color
Composite decking is available in various colors. Pressure washing can cause the color to fade or become uneven if the pressure is too high or the cleaning solution is unsuitable for the surface.
How to avoid this: Use a cleaning solution designed for composite decking and test a small area first to ensure it doesn’t cause any color fading or discoloration.
Voiding the warranty
Most composite decking manufacturers provide a warranty that covers defects, fading, and staining.
However, using a pressure washer with a high PSI rating or the wrong cleaning solution can void the warranty and leave you responsible for any repairs or replacements.
How to avoid this: Check the manufacturer’s guidelines and warranty before pressure washing your composite decking, and use the right equipment and technique.
Damaging the surface
Composite decking is made of a combination of wood fibers and plastic, and it’s designed to resist rot, insects, and other outdoor elements.
Using a pressure washer with a high PSI rating can damage the surface and cause it to deteriorate over time.
How to avoid: Use a pressure washer with a low PSI rating and avoid using it too frequently or aggressively.
Pressure washing can cause damage to your composite decking if it’s not done correctly. To avoid potential risks:
- Use a pressure washer with a low PSI rating
- A wide-angle nozzle
- Cleaning solution specifically designed for composite decking.
**Additional tip: To prevent the fibers from being too disturbed, the water must be applied evenly and gently to the deck boards.
What Are The Different Types Of Composite Decking, And What Is The Appropriate Pressure For Each Type?
Composite decking is popular among homeowners due to its durability and low maintenance. However, to keep it looking its best, occasional cleaning is necessary.
Pressure washing is an effective way to clean composite decking. But using the appropriate pressure and technique for your specific type of decking is important.
Plastic and wooden fiber deck
The most common type of composite decking is made from wood fibers and plastic. This type of decking is relatively easy to clean with a pressure washer.
You can use a pressure of no more than 1500 PSI. If you use too much pressure, you risk damaging the surface of the decking.
Plastic and resin
This type of decking is more durable and resistant to fading, staining, and scratching, making it a good option for areas with high traffic or exposure to the elements.
When washing this type of decking, use a pressure of no more than 2500 PSI to avoid damage.
Composite decking made from wood fibers, plastic, and recycled materials is also a great option for eco-conscious people.
Use a pressure of no more than 1500 PSI to avoid damage.
Capped composite decking
Finally, there are capped composite decking options, which have an additional layer of protection on the surface.
This layer helps to prevent fading, staining, and scratching, making it a good option for areas with high traffic or exposure to the elements.
Use a pressure of no more than 2000 PSI to avoid damage.
There are many types of composite decking, each with unique features and benefits. It’s essential to use the appropriate pressure and technique for your specific type of decking to prevent damage to your deck.
Trust A Professional Pressure Washing Company
While pressure washing can effectively clean your composite decking, it’s important to know the potential risks and how to avoid them.
Scratches, color fading, and voiding the warranty are all risks associated with pressure washing if not done correctly.
However, pressure washing can also benefit your composite decking by removing dirt and grime, preventing mold and mildew growth, and increasing longevity.
By pressure washing your deck correctly, you can restore its appearance and prevent damage from outdoor elements, saving you money in the long run.
