Bioesque Mold & Mildew Stain Remover provides the fastest acting and deepest cleaning available for erasing mold and mildew stains. Our innovative formula clings to the surface, allowing the advanced surfactants and Sodium Hypochlorite to penetrate deeper than any other product. Our professional-grade formula is ready to use, simply apply with any corrosion-resistant sprayer and watch the stains disappear before your eyes. Bioesque Mold & Mildew Stain Remover is a cosmetic product and is not a substitute for mold remediation. In order to kill the fungal growth (mold removal or mildew removal), first, use Bioesque Disinfectant Solution as directed and then use Bioesque Mold & Mildew Stain Remover to eliminate mold stain. This should be followed by applying Bioesque Mold Resistant Coating to prevent mold growth.
