Rated 5 out of 5 by from Great Product Proof is in the pudding. I used it both ways. Diluted and full strength. Last year, lots of mold. Some areas were huge patches of black mold. I cleaned our siding, porch ceilings, gutters, and molding. This year very little spots came back this year. Amazing product. It does what demonstration says. Here in Alabama humidity is an issue. Won't be without it.

Rated 5 out of 5 by from Incredible! This product is fantastic! I have used it on my white vinyl siding, pvc fencing, patio furniture, you name it. It's concentrated so you really don't need that much. It's easy to use and all you do is spray it and leave it. It says it may take a few months to work on hard stains but I found it takes less than a week on stains that I would have considered tough. It's a great (and inexpensive) answer to power washing.

Rated 1 out of 5 by from Works in some applications I bought this for the black stains on shingles, but it had no effect on that. It did however kill the lichens growing on the LP tank and on my horse trailer. It was quite a lot of work using a hand pump sprayer on the roof, and it is disappointing that it had no effect and it is 3 months since the application.

Rated 5 out of 5 by from Great stuff We are in charge of keeping the Grave stone clean for our family's. So I got this to see if it would work because it take a lot work to scrub them. So we sprayed them in the 1st of June and have not been back until Aug 1st and can believe how great they look. Some look completely clean other need a second spray. But We were very happy with it, will be spraying again and doing a little scrubbing to get some of the tougher area . Will start next year spraying in the spring and fall. to keep up with. You just have to remember it take time.

Rated 5 out of 5 by from Worked like a charm We have a waterfall in our backyard. We always battle algae growing on the rocks. We're were always looking for a solution to the problem.. Wet & Forget did the trick with little effort.

Rated 3 out of 5 by from Sprayed as Instructed - Not Working Yet I understand that this may be a long process for the product to actually work, but since that's a year or so and I wouldn't be able to leave a rating then, I wanted to leave my rating now. I live in northern Michigan and my house is about 150' from Lake Huron. The trees shading the roof have caused moss to grow on the roof so I sprayed this on the roof following the directions. Even in the areas of the roof where the sun hits it directly, it hasn't yet done anything (been on there about a month). What it did do is change the color of my roof! My roof is a light grey/green asphalt roof and everywhere I sprayed Wet & Forget, it turned it a much, much darker color! Which scares me because it doesn't look good now. I'm holding off on giving this a good or great review until I actually see some results. Several friends, family and neighbors are waiting to see if it works before they purchase it. I was going to use it on my sidewalk but after seeing how it darkened my roof I decided not to chance it. I used a powerwash on the sidewalk and it looks great. Hopefully the roof will look great, too, sometime soon.
