303 Mold & Mildew Cleaner + Blocker - Available in 16 oz. and 32 oz.

303 Mold & Mildew Cleaner + Blocker tackles existing mold and mildew stains on boats, RVs, canvas, upholstery, and other surfaces while helping block future growth so the problem does not simply come right back. The spray-on formula is easy to use on contact surfaces around the cabin, cockpit, canvas, and vinyl, making it a go-to for owners who need a fast, reliable way to keep mold and mildew from taking hold in damp marine and outdoor environments. Choose the 16 oz. bottle for spot treatments and smaller boats, or step up to the 32 oz. size for larger vessels, RVs, or routine fleet maintenance where more coverage is needed between refills.

Sizes & Options

Both sizes contain the same 303 Mold & Mildew Cleaner + Blocker formula, so the choice comes down to how much surface area you need to cover. The 16 oz. bottle is a convenient option for touch-ups, smaller boats, or trying the product for the first time. The 32 oz. bottle is better suited to larger boats, RVs, or owners who clean mold and mildew regularly and want to avoid running out mid-project.
