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

So far so good. It has been 3 days since I applied this to my Roof. I already am finding small pieces of dead Moss falling off my roof onto my deck. The moss has gone from green to brown. It was easy to apply and was a very fast process. I ordered another bottle to finish the rest of the roof. The only hard part was getting the hose up the on the roof. It comes out with Suds like soap so it is easy to see what is done. If something changes I will update this

I’ve used WET & FORGET for five years now. This is a great product. It will kill the algae overtime and will save you tons of dollars on your siding and your roofing. Now I don’t even wait for the algae to appear. Instead, I spray the roof and the siding once every year to prevent the algae from forming in the first place.

We like this product but are highly disappointed in how it was sent and left in our mailbox!!! No box or anything!

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.

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.

We had significant moss on our roof shingles, I used an entire bottle of this on the areas that needed it. I'd say it removed about 60% of the moss. I like the concept and perhaps I just need to buy another bottle for another round, but I still had to go back and spray off the moss that the product didn't take off.

This worked so well on my deck. I sprayed the whole deck with it and it so much cleaner within hours. It worked very fast. I was planning to power wash the deck but after using this product I no longer felt the need. Highly recommend.

This stuff is amazing! Just spray it on with a garden hose and leave it. Over the course of 3-4 weeks, all the algae and other stuff is wiped away clean! Highly recommend
