Rated 4.0 out of 5.0 by Worked well for black crud in shower My shower always gets black spots in the corners, on the window sill and on the sliding doors. This product was very good at loosening this crud (I'm guessing it is some form of mildew) so that it could be removed with shower spray or some very gentle scrubbing with a soft brush. No elbow grease required. It's hard to say if it lived up to its promise of blocking the return of mildew, but I wasn't very diligent about applying the spray regularly to prevent return - used it more directly on the spots when they reappeared. I would definitely buy it again as it was a lot more pleasant to use than bleach-based cleaners. July 25, 2010
Rated 4.0 out of 5.0 by Mildew Stain Remover The Mildew stain remover plus blocker for mold removal worked better than expected. January 2, 2015
Rated 5.0 out of 5.0 by Easy application, cleaning and blocking of new mold growth. We used this on our church central a/c unit to clean the coils of mildew and the downstream ducts and air registers. The stream/spray bottle gave us a long reach for good coverage. Everyone appreciated the resulting clean air smell without the moldy odor that they were used to. October 22, 2011
Rated 5.0 out of 5.0 by Great Mildew Fix. If you are having trouble with mildew around your home, especially on the north side of your house or roof, give this product a try. May take repeat applications, but give it a try. June 18, 2012
Rated 5.0 out of 5.0 by Great on Fragile, Painted Surface I loved it! My situation: Old home, insufficient ventilation. Bathroom finished with maximum texture and matte-type, easily marred, easily removed paint. Therefore, any wiping or brushing is out of the question when trying to clean it. Although the manufacturer makes no recommendations to use it in my situation, I was desperate to find something that would work without damaging my walls. I decided to take a chance on this product and was enormously pleased by the result. I sprayed on the Mold Armor as soon as I saw mildew begin to form near the ceiling and it caused the mildew to disappear. I did not re-apply it until I saw it beginning to return (weeks or months later), so I'm not sure about how the blocker would work in a more normal situation. I was delighted to find it worked without any negative impact on the texture or the paint. I found this product pleasant to use -- even in winter when I couldn't open windows. Since it did such a great job on such a sensitive surface, my next application is to try out the "blocker" in my shower! September 13, 2010
Rated 5.0 out of 5.0 by The Best Purchase I've ever made! This product is amazing! After failing with using bleach weekly to remove mold; I researched to find this product that will get rid of mold and keep it away. This product has been used once in my window and no mold has grown back yet. It was about a month ago since I used it! June 3, 2014
Rated 2.0 out of 5.0 by Disappointing This product previously contained chlorine bleach and was extremely effective. Now, the bleach is omitted and while the cleanser is much less caustic, it is also much less effective. November 11, 2014
Rated 1.0 out of 5.0 by High hopes...Big let down! Got this products and was excited to use it. I sprayed it on our stucco exterior, portion of our gutters, and on our tile tub. I was expecting it would going to "melt" away the mildew/mold. What we got from the product was a big fat nothing. I sprayed it twice on the tile and waited. No change in color, intensity of mold/mildew, or anything. I could have just put water on the area. ***DO NOT WAIST YOUR TIME OR MONEY ON THIS PRODUCT*** March 18, 2012
