ᐅ Remove green moss from WPC fence and natural stone patio tiles

Good evening,

I have quite a lot of green moss on the WPC fence and natural stone terrace slabs. What would you recommend as the best treatment, preferably avoiding strong chemicals (if not, the options seem overwhelming). Thank you very much!

Baking soda and hot water. Let it sit overnight. If that doesn’t help, then go for the chemical cleaner. Otherwise, of course, mechanical cleaning with a pressure washer.

I use the back side of a garden tool (hand cultivator) to scrape off thick clumps. Or do you mean more the algae buildup?

This spring, I cleaned the terrace and path using a pressure washer with a surface cleaner. It works great and looks like new. With WPC (wood-plastic composite), you need to check if this method is suitable.

Hello everyone. The problem with the pressure washer is that the panels rest on gravel, and I think the gravel will get washed out of the joints if I use the pressure washer here.

Has anyone already cleaned WPC fences with a pressure washer?

PS: I actually do have a surface cleaner attachment for the pressure washer.
