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

Great spray. Works perfect. A quick spray down on the side of my house and leave it alone just to see the difference within a 24-48 hour period. It doesn’t harm my grass or my pets. Doesn’t have a harsh smell to it and don’t burn my skin if I get a little on me. It works fast and cleans the green algae off the side of my home like a professional. Looks great.

You must read the fine print and believe it. It says “Green stains clean up within 1-2 weeks, black stains or heavy, stubborn stains can take several months, long-established stains may take 6-12 months.” My house has vinyl siding which has been cleaned numerous times using a chlorine based vinyl siding cleaner. I applied this new product last month and I have seen virtually no improvement. Also on a totally windless day the spray might possibly reach 20 foot, and that is with the narrow spray nozzle. If there’s any wind, you’ll be lucky to get 15 feet. If you put on the wide area spray nozzle you’ll probably only get your face wet with even a small amount of wind. The product foams, and when you raise the sprayer, the product doesn’t dispense well, so when trying to hit higher levels, you’ll get mostly water, and that is with a full bottle of liquid. Today I applied 2/3 water +1/3 chlorine bleach, and sprayed the front of the house and it cleared up almost as I was spraying! The stains on my house were not what is described as long and established stains, but if they were I didn’t have a year to wait and see if this product worked. For the price, I’m very disappointed, not only in the liquid product but the sprayer.

This stuff worked great. My siding was discolored and I was about to be fined. I sprayed this and came back a few days later and there was a considerable difference.

I was very skeptical about this product, but it actually works. I sprayed the north side of my house on a Wednesday, checked it on Saturday and the moss was already gone. There was no rain during this time, only dense morning fog a couple days. Highly recommend this versus pressure washing.

This product is just like what the name says. You hook it to your hose, spray down the sides of your house, and forget about it. Within a few days your green mildew disappears. What more is there to say?
