Rated 4 out of 5 by 1reviewer.
Rated 4 out of 5 by Works as advertised! Wet and Forget was simple to use, just mix to the 5:1 ratio and spray it on! I used it on my siding and roof shingles a year ago, and only now am I seeing some return of the moss and mildew. I feel only one treatment a year is great. Although it works as advertised, I feel it is a bit pricey. May 22, 2012
