Wet & ForgetOutdoor Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Cleaner, Xtreme Reach Hose End with New & Improved Nozzle, 48 Fluid Ounces

This stuff is great. I have been using it for years. We have vinyl siding and this is gentler than a power washer or harsh chemicals. Just spray it on. The mold and mildew stains will disappear slow but wont come back for a year or two. Heavy staining may take two applications.

I used this on my house and after about 6 weeks the outside of my house was cleaned. The best part was the application. It was very easy. You just hook it up to your hose and the product sprays where you want it.

Took a while after application, but my roof and deck have cleared off the algae.Not dirt, but I didn't expect it to.You can get it at Costco for $22 as of 2025, so not a good deal online.

This is easy to use and really works. I tried the attachable spray head but it wouldn't stay in place, but using no head it sprayed and covered well. It quickly killed the algae. Just waiting for rain to wash it off. Perfectly named, wet and forget.

Did the job on my vinyl siding. Sprayed waited and the moss was goin the next morning.PS THE BATHROOM WET & Forget works too!

I just applied this product to my patio pavers so I won't know if it works for a while. This review is all about the delivery system (the part that the garden hose attaches to). It doesn't work well because: 1. You attach the hose with the water off. When you turn it on the product sprays out in a huge arc, spraying the yard. 2. The nozzle has 3 settings, Off, On, and Water. You rotate it to set it- and that's a huge problem because it continues to spray as you're trying to get it under control. This means you're twisting the nozzle connection AND the hose at the same time while the product and water flows under pressure. 3. There is a plastic attachment to the nozzle that is supposed to regulate the stream to either Jet or spray. It's flimsy and it flew off when I adjusted it the first time. After trying again the only setting I could get to work was Jet. I wanted Spray for my smaller area. 4. There is no way to know when the container is empty because water is still flowing through it at force, so I'm pretty sure I sprayed water on the pavers after the product was done, thereby diluting it. I would not recommend this product at all.

This product worked exactly how it was intended. Very quick and removed all of the mold on the side of the house. The only reason for a three star review is because it killed all of my plants and grass in the area I used it.

This stuff is awesome I’m hooked for life
