The Iosso Fabric Cleaner and Protectant kit comes with Iosso’s Mold and Mildew Stain Remover Cleaner, which removes tough stains. It doesn’t contain bleach or chlorine, so it won’t harm or discolor boat covers, tarps, cushions or carpeting. The kit also includes a 32-ounce bottle of Water Repellant concentrate. Used after cleaning, the concentrate is sprayed on fabric to repel water, soil, and oils, and resist mildew and stains. It dries completely with no residue.
