Mold and mildew stains often show up in damp, humid areas where moisture lingers, such as bathrooms, laundry areas, and around washing machine seals, grout lines, baseboards, and other hard-to-dry surfaces. Using a stain remover designed for these areas can help address visible buildup before it becomes harder to remove.
After cleaning, keeping surfaces as dry as possible can help reduce future staining. Wiping down damp areas, allowing airflow into bathrooms and laundry spaces, and cleaning problem spots regularly can help prevent mold and mildew from building up again.
For best results in front loading washing machine, product should be applied once per week, soon after using machine. Surfaces need to be allowed to dry after application. If mold is left on surface, like rubber gaskets or grout, for even a week, mold can embed into surface, in which case product will no longer work effectively.
Our product is safe to use on fully cured and oil based painted surfaces only. Always spot test first. Do not use on powder coated or aged/worn painted surfaces.
