This stuff is great. (Can I end it here?) My composite deck looked awful with black mildew over about a third of it that lies under tree branches. I used it as directed last fall (it took a little more than "light" scrubbing), and it looks 100% better. I plan to use it again probably in March or April, and after that, I see easy maintenance with Corte-Clean from now on. I've uploaded a photo, but it's rotated 90 degrees, for some reason.
