X-14® Professional Mildew Stain Remover is a ready-to-use bleach-based mildew stain remover for boat and RV hard surfaces when organic staining needs a dedicated spray—not a general APC.

Manufacturer says it penetrates and works without scrubbing on many mildew stains, and is also positioned for sealed grout, tile, vinyl, and plastic. MDSC carries the pro-oriented size for detailers.
