Presta X-14 Mildew Stain Remover - 16oz

The Presta X-14 Mildew Stain Remover is a concentrated marine cleaner formulated specifically for boat owners and water enthusiasts who battle the persistent challenge of mildew growth on canvas, vinyl, and gel coat surfaces. After years on the water, any boater knows that mildew doesn't just compromise appearance—it degrades protective coatings and accelerates material deterioration if left untreated.

This 16 oz concentrate tackles stubborn stains caused by moisture, salt spray, and algae accumulation that occur during storage or extended time in humid climates. The X-14 formula works through active bleach chemistry that breaks down the cellular structure of mildew colonies, and it is designed to be diluted based on stain severity—light cleaning requires greater dilution, while heavy mildew buildup demands a stronger concentration.

Serious boat owners rely on the Presta X-14 Mildew Stain Remover for canvas covers, dodgers, bimini tops, cabin interiors, and exterior gelcoat surfaces where mildew thrives in damp conditions. It's equally effective on cushions, upholstery, and vinyl railings—anywhere moisture creates the perfect environment for mildew growth.
