rip-off
Spray and Forget used to work, when it contained Alkyl dimethyl benzyl ammonium chloride. Now it doesn't do anything and they have some nerve charging these prices for a potassium hydroxide solution. If, despite the negative reviews, you decide to buy it, save your receipt to get your money back. But they won't give back the time you wasted.

    Only my footprints came clean
    Sorry, I cannot recommend this product. Application was not a problem but only a small amount of dirt/mildew came off my roof and the only areas to really come clean were my footsteps. Now my roof looks worse than before. Two "after" pictures attached, did not take "before" photo.

        Product has been great on roofs. Keeps moss away and also works on algae and clears up black stains, have had to reapply if it was raining. Gallon markings on the 5 gallon jugs would really help. Most often we only use a gallon or two at a time. So we have to mark them up before each use.

        The old formula comes in this size . The new formula comes in the smaller size . The 5 gal formula is the best for roofs and cement that has moss or algae. It works better than yhe new formula .

        Complete waste
        Please don’t make the same mistake we did. This product did absolutely nothing for our roof. We read the instructions many times to make sure we did it correctly. Our roof doesn’t look any different.

            We apply with a pressure washer that mixes air and comes out as a foam. Applied during dry season and didn't think it worked. Got a few heavy showers and all the neighbors thought we'd put on a new roof. My 19 year old roof looks like it was put up yesterday.

              Did not work at all, was supposed to turn orange, but, it did not do anything; ended up using a power washer.

              No It’s a different formulation than what was available last year. This product must be rinsed off. This defeats the name that’s still on it “Spray and Forget”This wasn’t apparent to me until at home. Product was returned

              New formula doesn't work and should be called spray and rinse not spray and forget because the new formula calls for it to be sprayed on and immediately rinsed off and it doesn't work at all
              The old formula that you spray and forget worked...this new formula that you spray and rinse immediately doesn't work don't waste your time or money unless you can find some of the old that is actually spray and forget

              This did not clean my roof, I used one bottle and one refill bottle and on one section of my roof with almost no change with the discoloration. I would not recommend this for a dirty roof...

              This is the best thing to use on your driveway, fence or house. No need to bring out the pressure washer and it does the work in about 1/4 of the time. I used this for the past 8-10 years now.

              THE NAME SAYS IT ALL
              I've tried several products over the years for mold and moss. Most do ok but Spray and Forget is the best by far. I've used it on the roof, driveway and landscape river rock. Be sure to cover any plants when you spray. Then nature will do the rest !!
