303 Mold & Mildew Stain Remover – 16oz

Pulled the cover off in spring and found mildew on the seat? 303 Mold & Mildew Stain Remover takes those stains off vinyl, plastic, painted surfaces and fabric, and it does it without bleach.

Skipping bleach matters on a motorcycle. Bleach is harsh on seat vinyl and stitching, and it leaves a smell. This leaves a fresh scent with no strong odor during or after use.

• Removes mold and mildew stains on contact.
• No bleach.
• Works on all water-safe surfaces: vinyl, plastic, painted surfaces and fabric.
• 16 oz. Made in the USA.

How we’d use it: spray, let it work, wipe with a clean microfiber and let the surface dry fully before you cover the bike again. Try a hidden spot first on anything you’re unsure of.

Mildew grows where damp air gets trapped. Once it’s clean, a No Damp moisture absorber helps stop it coming back, and our guide on how to make a motorcycle cover last covers airing a cover out. This 16 oz bottle is also in our Winter Storage Kit and Cover Care Kit.
