    Looking for a solution or product to clean my composite deck. I tried a small sample spot with the pressure washer and even turned down it stripped the color off the area. So I’m hoping to find something to spray on and scrub with a push broom and then hose off maybe ? Or what other options do you have to clean the composite boards. It’s starting to get black and green spots all over.

    Manufacturer may have recommendations.

    Yeah, keep those pressure washers away from composite.

    Luckily I was smart enough to try a sample spot in the corner. And I had it cranked way down. How does one know who what composite it is ? I’m not the builder ? I don’t see any labels underneath

    I used the spray on bleach and it worked. I also scrubbed it with Simple Green and it worked. The bleach is pretty easy to do. The scrub brush was a work out. Neither one lasted long enough. But I have overhanging walnut trees which drop stuff all year.

    Don’t overthink it. Trex guys that deliver to us on my summer job say dawn dish soap and water. A real light fast hand scrub cleans ours at the house right up

    I use Dawn Power wash and a brush. It took rust stains(snow shovel) right off my deck.

    FYI Dawn Powerwash is just Water, Dawn, and Isopropyl/rubbing alcohol.

    2 cups water
    4 Tablespoon Dawn
    2 Tablespoon Alcohol.
