What to know about cleaning 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.
