Rated 5 out of 5 by from To cold outside to use as yet. I gave this 5 stars because IF it does what they say it will I will love it. It sounds so easy. I need easy because I'm not young anymore!

Rated 5 out of 5 by from Great Purchase I had green mold/mildew on my brick house about a foot up from the ground and I wondered how I could remove it. When I saw the presentation about Wet and Forget, I thought it might work and to my pleasant surprise, it did! Within 24 hours after spraying, the green stuff was completely gone! I am very happy with this purchase! Very easy to use, too.

Rated 3 out of 5 by from WARNING !! I don't suggest anyone ordering this if your purchases have to go though cold states. I got mine and it was frozen solid like a rock. Sure hope it will work this summer since I paid so much for it.

Rated 5 out of 5 by from It Works! I tested an area of vinyl siding on our home. I'm very impressed with how well this product works. I mixed it according to the directions, sprayed it on and left it. I will definitely use it on the whole house.

Rated 5 out of 5 by from Miracle Worker This product is a miracle worker! At first I wasn't sure it would work. I added it to my garden pump sprayer and applied it to the surfaces that were turning green. I did not see any immediate change but after about 30 minutes I could see that that the green stuff that was starting to creep into my outdoor carpet was disappearing right before my eyes! It has been months and nothing has come back and it saved me having to drag out the power washer and scrub away --- - and it was quick!

Rated 5 out of 5 by from Wow This is a great product. I swept my deck, sprayed the product. In 3 days I saw a huge difference! At 2 wks no more green! Easy easy to use. It just doesn't get any easier than this!

Rated 5 out of 5 by from Really works well! We live in North Carolina so mold and mildew are a real problem. We have used Wet & Forget previously and found it to be really effective and it does not harm plants. It does not act immediately but works really well. Thus the name Wet & Forget. We have recommended it to others including our daughter.

Rated 1 out of 5 by from Waste of money This product did not do anything. Very disappointed in the product. I was hoping this would clean the black off my driveway but it did not. I followed the instructions but after waiting several weeks of no change I ended up pressure washing. Waste of money.
