Removes mold, mildew stains, and odors on contact. MB-9 Mold & Mildew Remover cleans effortlessly—no scrubbing required. It eliminates mold, mildew stains, and odors instantly while leaving surfaces sanitary. Regular use (every 2 to 4 weeks, depending on exposure) helps maintain a clean and mold-free surface. Safe for most natural marble surfaces, but always test on a spare tile or inconspicuous area before use. Directions for Use: Spray liberally onto the affected area. Allow the mold or mildew stain to disappear—do not let the product dry on the surface. Rinse thoroughly. Repeat as needed. For stubborn, old stains, use a soft brush to help break up residue. If used on food-contact surfaces, rinse at least twice.
