Works as described. I first removed the moss from the pavers on the patio. After applying the product, the patio remained moss free for several months. Getting ready to apply another application and don't think I'll have to manually remove much moss.

    Purchased this product to remove mold from my metal roof. It did not work; even after six months! When I contacted their customer service about their "guarantee", they told me that the product does not remove dirt and that they would not stand behind their guarantee. I explained to them it was black mold and they still would do nothing. In essence, the product doesn't work and they do not stand behind their guarantee. Don't waste your money!

      Made quick work of green algae on siding and sidewalks. Did not affect black staining on painted metal between windows. Will definitely use again. Prior I mixes some bleach into sand and brushed my sidewalk with good effect, this is so much easier.

      I was a little skeptical of this after I used it. Nothing seemed to happen. But....after about a day...boy, ok, this DOES work. Mix it with the right amount of water and it does the trick. It's a bit pricey but I was able to cover a lot of surface with one bottle.

        There was no visible change in the stains on my painted brick outside. A few stains usually appear every few months or so from the water that runs off of my patio roof onto the back of my house. I wire brushed the moss that had collected and applied Wet & Forget (about 3 weeks ago); stains are still there. I got much better results from spraying the stains with Clorox Cleanup, allowing it to soak for about 15 minutes and hosing it off. I was disappointed with the product.

        Hi Lorelei! Wet & Forget is a gentle cleaner that works over time with Mother Nature to remove moss, mold, mildew and algae. If the stains on the surface are more green in color, you should see results a few weeks after applying, if the stains are black it can take a few months for you to start to see a change. We'd like to look into this further and learn a little more, if you could please give our office a call at 888-727-8524. WetandForget

        Wet & Forget Outdoor will not create results directly after applying the product. It works over time with the wind and rain to gently clean up moss, mold, mildew and algae. We would like to learn more about your experience with Wet & Forget, if you could please give us a call at 888-727-8524. WetandForget
