I have used Wet & Forget for three years to protect the screens in my screen porch from developing moss, mildew, and that Green Gunk. Before using it, I had to powerwash the screens from the outside, which is not simple. Now, after my annual powerwash of the porch screen room and screens from the inside, which is simple, I use a mop-like tool to wet the screens on the outside, which is also simple. Spraying doesn't work well because the product goes through the screen into the screen room and takes a lot of product. Using a mop-like thing on the end of a pole is a quick, effective, easy job. It really, really works to stop the Green Gunk, and my screen porch is mostly North facing. Cheap, effective, simple to put on. Oh yeah, I called the company before using the first time to ask if the produce would harm or deteriorate the nylon screen. Nope.

I have already tried the product. It was good. The mold and algae were slowly disappearing. I will sure order again. Only thing i hope is the seller can lower down the price a bit as it's quite an expensive product.

I decided to give this a try after doing some researching it. It's not exactly what I would call cheap to purchase. My sole purpose was to try it on gravestones. This was in the spring. My parents grey granite stone had a black stain on it about 3" x 6". I sprayed the entire stone with the Outdoor Wet & Forget. My grandparents grey granite stone that's 50 years old was covered with different colors of mold. I sprayed that one completely too. I didn't scrape or scrub anything on either stone. Both stone are in 100% full sun all day. I used a professional sprayer bottle I bought on Amazon. When I went back to the cemetery end of summer I checked out both stones. On my parents stone the black stain was almost all gone. My grandparents the moss had turned into a tan sandy looking sort of stuff. I used my hand to rub hard against the stuff and the stuff was coming off. I sprayed both stones again and I came back first week of October. My parents stone looked good. My grandparents stone there was a big difference. There were still some spots that had that dried out mold on it. I sprayed both stones again. End result is both stones look brand new. I want t o add in here I used it on my black granite stone and have not noticed any changes at all. Maybe the only change is maybe it would have got mold on it too if I hadn't sprayed it along with the other two. It doesn't look any better or any worse than the day it was set in the cemetery. I rate Wet & Forget 5 stars, And that's my review.

I was very surprised how well this worked. The side of my house (see red highlight in pic) had algae growing on it. I sprayed on wet & forget and within a few days can see an amazing result. I will definitely buy it again.

Does as advertised. Gets siding clear. I live on a lot of land. I did notice that earthworms came to the surface and writhed in agony in areas where I applied this. Other insects seemed to be extremely bothered, most fleeing even light applications. I'm no naturalist, and I seemingly have enough gross worms to seemingly repopulate the world, even after application of Wet and Forget. But, maybe keep your cats and dogs away for a few days after application.
