2-pack Wet & Forget Outdoor Hose End Refill - Nozzle Not Included - 2 Pack — Garden & Landscape Use, Standard Connection

When I moved into my house the shed roof was covered in moss. I sprayed this and now I have a moss free roof. I bought more because the roof is starting to grow a little moss a couple of years later. You spray it and then don't have to do anything. The birds eventually ate the dead moss.

I've used this product for over a decade and swear by it. The Extreme reach nozzle version really helped get upper level siding without needing a ladder and made cleaning much easier. No scrubbing needed. Spray and wait a few days. Works very well.. It can affect some plants so cover them or soak them down with water before and after.

easy to use very effective

Applied over two seasons and all traces of discoloration are gone.! Good product!!

Works great! No one walking on my roof and potentially breaking the tiles…

I've bought this product several times and have always been happy with it. It works beautifully and is easy to apply.

Always good service

This product works well, but it is expensive! I first power-washed my house with just water %26 was able to get most of the green off the vinyl siding. Then I used the sprayer (from the Wet %26 Forget Window Washer treatment) with the Wet %26 Forget for the house, especially getting the upper parts of the house, that I could not reach with the power washer. I waited until the rainy days were over, so that the product would not be diluted %26 less effective. Great product! Recommended by my Professional Handyman and my neighbor.
