I mix all my own chemicals....believe it or not i carry 2..and acid and an alkaline. The alkaline is used for house washing and even deck stripping at full stength. I wash trucks, houses, decks, and flat work with the same soap at different dillutions. The acid is used to brighten aluminum or to 2 step. I have found that a high enough ph will kill mold ....at least in ohio. I've heard about the mold down south but i've never experienced it first hand. I just feel bleach is pretty scary to use with plants and possible streaking. Someday I would love to come down there and see how you use it. I'd be happy to bring some of my cleaners for you to try.
