Fiberlock Instant Mold Stain Remover is a high-performance cleaning solution engineered to aggressively remove stains caused by mold and mildew. Designed for professional remediation and restoration environments, this powerful formula works quickly—often within minutes—to target and break down deeply embedded discoloration on affected surfaces.

Formulated with sodium hypochlorite, the product penetrates porous materials to lift and eliminate stubborn staining, helping restore surfaces to a cleaner, more uniform appearance. It is particularly effective on wood and concrete substrates, making it an ideal solution for applications such as attic sheathing, basement areas, and other areas where mold staining commonly occurs.

For best results, Instant Mold Stain Remover is applied undiluted using a pump sprayer designed to handle corrosive solutions. Coverage typically ranges from 200 to 500 square feet per gallon, depending on surface porosity. Heavily stained areas may require multiple applications, followed by rinsing and drying to achieve the desired result.

This product is intended strictly for stain removal and does not claim to kill or inhibit mold growth. Proper cleaning and remediation procedures should be followed prior to and after application. Users should take care to avoid overspray on non-target materials, as the formula may cause bleaching or corrosion on sensitive surfaces such as fabrics or metals.

With its rapid action and strong cleaning capability, Fiberlock Instant Mold Stain Remover provides professionals with an efficient and effective solution for addressing mold-related staining in demanding environments.
