Review: Great for screens! - 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.
Review: Works outstanding with a little time. - 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 desertcart. 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.

## Questions & Answers

**Q: Can this be used on a blow up bounce house**
A: I used  it on brick and in one day the moss was gone and has not returned. For you  I would try it on a piece of plastic like a baggie first seems save to me.

**Q: Does it work on mineral deposits on outside windows?**
A: Hello!  Wet & Forget will only remove organic growths such as moss, mold, mildew or algae.  It will not remove mineral deposits.  If you have further questions feel free to contact us 888-727-8524.  The Wet & Forget Team

**Q: Can you use this for shower mold**
A: No. My mold is still there after using for many months. This product is "Septic Safe" (which hard to find) so no bleach etc.

**Q: will this work on outdoor carpet?**
A: Yes, I use it on the carpet in my fishing boat and pontoon boat. Does not stain or bleach the colors. Since fabrics differ I would try it on a sample or in an out of the way spot just to be sure. I had mold and moss on my boat carpet and it worked great. Get it soaked with the cleaner and bruss it in to get deep into carpet strands and just hose off after 10 to 15 minutes

### ⭐⭐⭐⭐ Outstanding work, but seems to kill bugs.
*by B***T on September 29, 2025*

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.
