Rated 4.0 out of 5 by 170 reviewers.
Rated 5.0 out of 5.0 by Great Product Although it's only been about 2 weeks I can see a difference. Based on other reviews I believe over time it will get better and better. May 31, 2015
Rated 5.0 out of 5.0 by Highly Impressed The directions were easy to follow. You will need a sprayer, recommend a gallon size which Home Depot sells for around $10 to mix the solution and spray. We have an enclosed patio that had algae stains on the stone floor and up along the walls. I applied wet and forget and after the first day wasn't sure if it was working. It is now day 3 and all the stains are gone. Make sure you saturate the area and allow enough time for the product to work before another rainfall. Recommend this product highly. June 30, 2015
Rated 5.0 out of 5.0 by Bye, Bye Mildew I was not convinced by the TV commercials that this would work as easily or quickly as shown- but it did! You simply do as it says- "Wet & Forget". The entire north side of my home was green and black with mold, mildew and algae. It took 3 minutes to mix the Wet & Forget (5 parts water to 1 part W&F) and under 10 minutes to spray. Within 24 hours 50% of the yuck was gone. After 3 days 75% clear. In one week it is 95% clear and it continues to work. My next door neighbors now have a much nicer view and are also using it. I highly recommend this product. July 22, 2015
Rated 5.0 out of 5.0 by Miracle Cleaner for my Inflatable! I recently had to perform maintenance on my inflatable that was under a boat cover for over two years. I was aghast to see the mildew that had grown! I convinced myself that it would never look good again. WAS I WRONG! I followed the manufacturer's directions, after a week the mildew disappeared with very light scrubbing!! A miracle cleaner!! July 28, 2014
Rated 5.0 out of 5.0 by Glad I decided to try this... Had a little trouble figuring how to mix w/water, but once mixed it worked really good. I sprayed it on my deck, left it and the algae was removed from my deck. I sprayed a little on some algae growing on the ground at my deck and it killed it. I had to order this product online. I just wish that Home Depot store where I live would stock it. June 9, 2015
Rated 5.0 out of 5.0 by Worthwhile purchase Our home is tucked away in a wooded area under a predominate canopy of oak and hickory trees. The resultant shading of the roof has made it susceptible to intense black mold, algae, and fungus over the years. Following the instructions to apply Wet N Forget to a dry roof on an overcast day, I sprayed the product in October 2013 to our ranch style home. When the snow had cleared from the roof sometime in March 2014, I observed all of the fungus and algae gone, but only some of the black streaking cleared away. It wasn't until May 2014 that a substantial part of the roof was cleared of the black streaking. By fall of 2014, the roof suprisingly appeared to have been restored to its original color! I'm very much impressed with the quality and performance of this product and would definitely recommend it. A caveat might be that the practicality of this product's usage is limited to roofs with a lower pitch. January 24, 2015
Rated 4.0 out of 5.0 by Good mold elimination treatment We have used this product in past years with great success. It prevents mold on our Trex deck and north facing vinyl siding. June 9, 2015
Rated 5.0 out of 5.0 by Excellent Cleaning Proudct! The Moss Mold Mildew and Algae Stain Remover lives up to it's name. A qulity product that does the job the first time. October 6, 2015
