Malco X-14® Professional Mildew Stain Remover
Marine Detail Supply Port Clinton stocks the Malco X-14® Professional Mildew Stain Remover for boat and auto detailers around Lake Erie and northern Ohio, with pickup at our Port Clinton shop.
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.
