Wet & Forget Outdoor Moss, Mold, Mildew, and Algae Stain Remover Concentrate, 128 oz

I have a large wood sided house and deck with lots of shade trees and surrounded by woods, a perfect situation for mold, moss and dirt buildup. My brother told me about Wet n Forget so I thought I'd give it a try and I must say that after using it for a few years now it performs exactly as claimed. I just spray it on where ever I see a bit of green appearing and leave it alone and after a few rains everything comes out clean. Seeing how good it worked I bought the version that attaches to your hose and sprayed the back of my house which started to have that same green tint and in a month or so it looks good as new and I didn't have to power wash or get on a ladder with a brush and soap. The results last a while and I didn't notice any color changes on the paint or stain. It's also great on my blue stone walkway. This is one of the best products I use and I highly recommenced it.
