          Worked very well, however, the 2.5 gallons did NOT go as far as the bottle said it would. The house used on is a 2 story Cape with attached Garage and a room above garage. Used 4- 2.5 gallons= 10 gallons!! My opinion, too much on the house. Caution: Does bleach your clothes!

          Used product on a fence. Let soak for 10- minutes then power washed. My 20 year old fence looks brand new! Fence hadn’t been power washed before. Highly recommend this product!!

          Awesome product. The fence was grey, which was fine, but we just redid the backyard so I wanted everything to be clean and fresh. I applied 30 min miracle with a sprayer mixed with water, let it sit for a few minutes and lightly scrubbed with a car wash brush and hosed it down! So easy and the results were amazing!!

          This stuff is great!
          We only used it in a couple of spots so far just to try it out - it did not disappoint! We didn't really scrub because it was just too hot today in the Florida heat. The results speak for themselves! Used a regular hose - didn't have to drag out the power washer!

            My mind is blown. This works,
            My deck sat for one year until we could stain it. We are now able to stain the seck. During the year it became black and spotted and very discolored in certain areas depending on sunlight exposure and overhead vegetation. I applied the treatment as directed and it turned the deck to brand new right before for my eyes. Will be usijg it now for washing the house.

              Holy Smoke!!! It worked!!!
              We were skeptical about it because at the first try we weren’t particularly patient with it. I’m just going to let my little video speak for itself and tell the rest of the story.

                It works without the damage that can be caused by bleach
                Truth is my wife uses the heck out of this stuff. She just acquired a used camper. Changed the tires on it and pulled it out of storage. Brought it home and went to work cleaning it. The roof is covered in vinyl, so caution is required not to poke a hole and when using caustic cleaners. 30 Second Outdoor Cleaner did the job. The camper looks like new!

                The Good and Bad
                I live in Florida and clean either pressure washer of use bleach with a tank sprayer every year to eliminate mold. This year I tried the 30 Second cleaner mixed as directed with water in a tank sprayer. It worked very well as claimed. 30 Second 24’ hose sprayer Not at all reached Did not reach 24’ but roughly 12’ to 15’ as a wide spray but no stream. Needed a stream to reach high areas of my home.

                30 SECONDS Outdoor Cleaner is made to safely remove stains from Algae, Mold & Mildew on most outdoor surfaces. We do always recommend testing in a small, inconspicuous area first. Spray a small amount of cleaner, let sit per surface directions on the bottle, brush if needed and rinse to see results. We appreciate your business, thank you for sharing your experience with our product.

                  Doesn’t clean dirty concrete
                  I used the concentrate in a one gal sprayer for my porch. And a hose end bottle fir the driveway. The hose end was empty after spraying on 2 sections. Neither cleaned very well.

                  30 SECONDS Outdoor Cleaner is made to safely remove stains from Algae, Mold & Mildew on most outdoor surfaces. We do always recommend testing in a small, inconspicuous area first. Concrete is extremely porous material and require the most saturation. Spray surface with cleaner, let sit and remain saturated with product for 15 minutes, brush if needed and rinse thoroughly with hose to see results. The saturation time will vary depending on the amount of buildup, and the porosity of the surface. We appreciate your business, thank you for sharing your experience with our product.
