Rated 3.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Awesome Product I had a severe mold problem on my shed roof, I sprayed the roof in May. I started seeing results within a few weeks the mold had turned brown. I started hosing off the loose material as time went on. The mold was all gone in July. The only problem I've got because of the severe mold was some scarring on the shingles and some of them are raised, but the ugly mold is gone. See before and after photos. July 19, 2013
Rated 5.0 out of 5.0 by This stuff really works! This is my second gallon. Used a gallon last fall on my deck and mildew still gone. This time I'm doing my fence and again it works wonders in a few weeks. I read many reviews before purchasing and seems like 1/2 the reviewers had issues... NOT ME. It worked great on my fence and deck in the fog and cool San Francisco climate. June 2, 2015
Rated 1.0 out of 5.0 by Wet&Forget Mold,Mildew and Alae remover. I used this product over 3 months ago. I have seen no reduction in the mold or discoloring caused by leaves on my roof. Yes, I followed the instructions THOROUGHLY. Attached to the product was a disclaimer - " FAILURE - This product is only effective if you read the instructions thoroughly. Failure to do so will result in you moaning and groaning that the product doesn't work and generally being a pain in the bottom. Make a positive change in your life will you, and read the instructions". At first I thought this was humorist but after using the product I can only assume the statement was a "CYA statement. I am 71 years old and do not enjoy getting on the roof of my 2 story house over 2 days and applying the product from the top of the roof. I used a 2 gallon sprayer since it was difficult carrying it to the top of the roof and this required 3 trips back and forth to fill the container. With a $60 investment and the difficulty in applying the product, you can rest assure I read and followed the instructions THOROUGHLY. November 3, 2013
