MB-9 Mold & Mildew Remover cleans without scrubbing. Removes mold, mildew stains, and odor on contact. Regular use (every 2 to 4 weeks, depending on level of use) will keep surfaces clean. It is safe on most natural marble surfaces. Be certain to test product first on a spare tile or inconspicuous area for extra caution before use.
Directions for use: Spray on liberally. Allow mold or mildew stain to disappear, be careful to not allow product to dry on the surface. Then rinse thoroughly. Repeat these steps if necessary. In the case of very old stubborn staining, you can use a soft brush to help break up stain. Drying is not necessary. If used on surfaces that will touch food, rinse thoroughly at least twice.
