Can You Pressure Wash Composite Decking? – 2024 Guide


Maintaining your property in the right way is crucial if you don’t want to replace or fix your goods every year. It is said that composite decking is one of the best choices if you want to invest in something that’s durable, good-looking, and easy to maintain. Even though this deck model does not require too much care, you still need to clean it if you want it to look good and if you want to get rid of all the dirt and debris. In this article, we are going to tell you if you can pressure wash your composite decking, and we will give you some tips on how to properly care for it.

Can you pressure wash it?


There are many people who try and skip corners and who think that they will do the best if they just get the pressure washer and remove all the dust and debris from their deck at once. However, just because you are going to be able to finish the job faster, it does not mean that you will be doing it in the proper way.

As you already know, composite patios are really durable, and they don’t easily get damaged, but this does not mean that you can do anything and everything on them.

The rule of thumb is that even though you can use this power washing option, you should be extremely careful and you should never use the most powerful setting. You don’t want to add too much strain to the material, and you don’t want to risk damaging it.

The best thing you can do is choose a wide nozzle, or you can just get a fan tip for the power cleaning system. These options will help you prevent any additional damage while still making the patio look perfect.

Note that it also all depends on the material that you’ve chosen, and on websites like, you can see that there are different boards that you can choose from.

Depending on the board and its physical properties, you can talk to the manufacturer or the seller and ask them if power cleaning is an option.

Ultimately, experts do not recommend you to use this option, and that you should instead opt for a traditional washing hose. However, there are measures you can take to still pressure wash your patio without damaging it.

Additional maintenance tips


When cleaning this part of your backyard, you should always sweep it before you wash it, and you should never remove large debris just with water. Opt for warm water instead of a freezing cold one, and never use hot water. Use a proper cleaning solution that will protect the boards and that will still do a good job when it comes to removing dirt and bacteria. You can use some types of dish soap and dilute it in water, or you can purchase products that are made for this purpose only.

If you choose to do the cleaning with a brush, never use one that has too harsh or pointy bristles, and never use more pressure than you should. Be careful not to scratch the surface, and never use harsh chemicals.

Talk to an expert if you want to make sure that you will be able to use your decking for years to come, and remember that it is better to work slowly than to rush things out and damage the surface of the composite boards.
