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: Easy to use and the green is gone - It worked! I had a lot of algae on a shady back deck. I read wet and forget would work, but it would take a long time, maybe even weeks. But in my case the algae was literally gone the next day after application. I'm interested to see if it also helps get rid of some other unidentified buildup on the deck railing, but that would just be a bonus at this point. I thoroughly saturated the railing on a somewhat cloudy day with no wind or rain. Maybe 12 hours later the green on my deck was completely gone. It did rain a little a few days later which I think is supposed to help reactivate the product or something, but by then all of the algae was already gone. The sprayer was easy to put together and easy to use. It's probably a little less economical but I like that this version was premixed so I didn't have to measure or add water.

## 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.
