Rated 5 out of 5 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 5 out of 5 by Best Mildew Remover on the Planet! I own a Professional Residential Housekeeping Service and we service homes that have natural stone showers. You have to be careful about the products you use in such showers because cleaners, especially those with bleach will damage the stone. Enter Mold Armor! This is the only Mildew Stain Remover product that I have found to be safe and effective in natural stone showers.It is quite frankly the best Mildew Stain Remover on the planet and it keeps the mildew from coming back! Another big plus about Mold Armour is the scent. Unlike most mildew cleaners, which have harsh vapors and smells, Mold Armor has a pleasant scent that is friendly to your lungs. Being exposed to harsh mildew remover or bleach vapors over a period of time can lead to C.O.P.D. Protect your lungs and use a cleaner that is less harsh on your lungs. In 14 years being in business, I have used my fair share of mildew stain and mildew root removers. Mold Amour is by far the best mildew remover product I have used. April 2, 2014
Rated 4 out of 5 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 5 out of 5 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 1 out of 5 by Used much more of the product than salesperson said and still did not complete the cleaning process. Sprayed on. Scrubbed with brush. Allowed to dry and rinsed. Repeated as per the salespersons instruction. It did begin to cut through the layers but I would need a gallon to complete a shower that was not that bad to begin with. March 4, 2014
