Rated 5 out of 5 by from Very Impressed! I was not looking forward to scrubbing the siding on the north side of my two story house this spring, so when I saw this I was doubtful but hopeful. Boy was I surprised when I went out THE NEXT DAY! The green was gone and the black was grey. Even if only lasts part of the summer, it was so easy and took so little I can do again with no problems.

Rated 5 out of 5 by from This product is great! I battle mildew every year in my patio area and alleyway. I used this product once and, a couple days later, you would never have known there had been a problem. I'm still amazed that it worked as well as was represented on QVC. So easy, and so effective.

Rated 1 out of 5 by from Don't waste your money I tried this on our house siding where there was light mildew. Didn't even touch it. Also tried on other areas with absolutely no results. It's going to cost a fortune to send back because I bought 3.

Rated 1 out of 5 by from Didn't work I bought this to use on my deck and rails to get off the green stuff. I was hoping not to have to power wash this spring. It didn't work for me, in fact, nothing came off and not only that, it left a residue that even after it rained and i tried to hose it off, won't come off so guess what, i now have to power wash anyways. Don't waste your money on this for vinyl decking and railing. Maybe it works on wood better

Rated 5 out of 5 by from This is the cure for mold and mildew! I wish I had known about this product when I lived in South Florida, where the humidity makes mold and mildew a constant battle. I didn't find this product until I moved to Southern California where conditions are very dry. Even though it is drier here, we had mildew on the top of a fabric gazebo, where water from so-called "marine layer" collects. Wet and Forget lived up to its name. We were able to spray it to the very top of the gazebo. Some of the mildew disappeared immediately. Wind and sun took care of the rest. Within a week, it was gone.

Rated 5 out of 5 by from AMAZING ! This product is amazing. We live in Florida and have 18" porous agragate pavers going down to our dock. They have been down there for quite a few years and were moldy and mildewed. We tried everything and nothing got them clean. We sprayed them with this product and not much happened - for a while. Then over a few months time with the rain beating on them, they are white and look like new. We call this a miracle product. Also used it on the brick siding and dock chairs and it works like a charm. So spray once and then let nature do all the work. Dan Hughes presented this product and he said it works over time - and he was right,.

Rated 5 out of 5 by from THE BEST!!!!!!!!!!!!!!! I have been using Wet & Forget for several years, ever since it was recommended by a friend. It is the easiest and the best product for removing mold, mildew and algae from my concrete driveway. It works on my wooden deck as well. Spray on the diluted solution and wait for the magic to happen! It may take a week or so before the stain is completely gone, but when it is gone it is gone for months! Do not hesitate to purchase this product.......you won't be disappointed!!!
