The Ultimate Guide to Deck Cleaning with a Pressure Washer

Are you tired of looking at your deck and seeing mould, filth and grime growing on it? Do you want to make your deck seem like new and have peace of mind knowing that it is secure for you and your guests? If that’s the case, a pressure washer deck cleaning might be just what you need. 

In this comprehensive guide, we’ll show you how to clean your deck with a pressure washer the right way, from start to finish, with the help of some basic tips and advice. So, let’s get started right away on renovating your deck into a stunning outdoor haven.


The deck must be properly prepared before the cleaning procedure can begin. To get started, clear the deck of any obstructions, such as furniture, plants, or other things. Put something over any exposed wiring, lights, or other electronics that might be harmed by water. Now, before you start cleaning, you should also look for any missing or loose boards or screws and replace them.

Choose the Right Pressure Washer

Deck washing requires a special pressure washer, so it’s important to choose the appropriate one. Most decks may benefit from being cleaned using a gas-powered pressure washer set between 2000 and 3000 PSI and using 2 to 3 gallons of water per minute. If your deck is constructed from cedar or pine, which are both softer woods, you should use a pressure washer with a lower PSI to avoid damaging the wood. Nevertheless, if you need to clean anything but don’t have a pressure washer, you may either rent one from a hardware shop or pay a company to do it for you.

Apply Detergent

It’s vital to apply a cleaning solution or detergent to your deck before you begin pressure washing it. The filth, grime and mould will be easier to remove and the cleaning procedure will be more efficient if you do this first. You can go with a pressure washer equipped with a detergent tank, or you can use a hand pump sprayer to administer the detergent. It’s wise to use a detergent that won’t damage your deck or the natural environment.


Once you’ve spread the detergent around, it’s time to get to work scrubbing the deck. To completely clean the surface, use a brush with strong bristles or the brush attachment of a pressure washer. Cleaning thoroughly includes giving those inaccessible nooks and crannies a good scrubbing.

Pressure Washing

Using the pressure washer to remove the detergent and dirt is the next step. When cleaning your deck, start at the top and work your way down, using long, even strokes to prevent streaking and wood damage. To prevent gouging or splintering, keep the pressure washer’s nozzle at least 6 inches from the deck’s surface. A greater pressure level might be required to remove stains or tenacious dirt from your deck.


Let the deck air dry before applying any new stains or sealers after giving it a thorough pressure wash. It might take a few hours to a day for your deck to dry entirely, depending on the weather and the level of sunshine. During the drying process, you should keep your deck clear of any obstructions.
