When we handle pressure washing for composite decking in Rhode Island, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. For composite decking, that means low-pressure wash.
Method and pressure
Cleaning solution: A composite deck cleaner recommended by the decking maker.
Caring for composite decking
Composite decking doesn't need staining, but it does grow mold and mildew, especially in shade and between boards. Most manufacturers recommend gentle cleaning, and some limit the pressure that can be used without affecting the warranty.
Avoid: High pressure and narrow tips, which can scar the surface and may void the warranty.
How often: Every year, more often in shade.
