I was wondering if the following would work well for a composite deck heavily stained with black mold. Power washing by itself never seems to really get it clean unless you go inch by inch.
What if I mixed a bleach/water (or olympic deck cleaner, or whatever) together with something to thicken it to a very loose runny paste. Anything. Flour, or anything similar. Just not something that will harden. Flour might be bad.
Then I use an extremely heavy-nap roller to apply it. It wont just fall between the cracks this way and will "sit" in the false grain.
I let it sit for some amount of time.
Then [garden] hose it off while it's still wet.
(?) The guys I've hired are having a hell of a time with this Rhino Deck.
