Mildew Stain Remover for Boats

Mildew Loves a Closed-Up Boat. Here's How to Beat It.

A boat under a cover or sitting on a lift is basically a greenhouse for mold: dark, damp, and no airflow for weeks at a time. That's why mildew shows up on seats, cushions, and canvas even on boats that get washed regularly. Bleach kills it but eats your vinyl and stinks up the whole cabin. Regular soap doesn't touch it at all. Boat Juice Mildew Stain Remover is built to break the mold down at the source, lift the stain instead of just bleaching it lighter, and leave a Mango Tango scent behind instead of a chemical one.

This page has what you need to knock out an active outbreak and keep your boat from turning into mildew's favorite hiding spot again.

Active Outbreak or Ongoing Prevention? Grab the Right One

Mildew is a two-front fight, killing what's already there, and prevents it from building back up. Here's the honest breakdown:

Active mildew or mold stains on seats, cushions, or carpet: Mildew Stain Remover. Spray it directly on the stain, let it sit for a few mins, wipe or scrub. This is the dedicated Mildew remover built for vinyl, upholstery, marine carpet, foam flooring, and canvas.

Everyday interior wipe-downs to keep mildew from taking hold: Interior Cleaner. Mildew loves a boat that sits closed up and damp. Wiping down vinyl and upholstery regularly with Interior Cleaner (which also lays down UV protectant) keeps surfaces drier and less hospitable to mold between deep cleans.

Wiping it all down: Interior Microfiber Towel. Built for interior surfaces, this plush microfiber towel is just what you need for a easy wipe-down.

Spray, Dwell, Wipe: Getting Mildew Out Without Wrecking Your Vinyl

1. Spray the product directly onto the mildew or mold stain.

2. Let it dwell for 30 seconds to 2 minutes and don't let it dry on the surface.

3. Wipe clean, using light scrubbing on tougher spots.

4. For stubborn or set-in stains, a second application is normal.

5. Follow up with Interior Cleaner to protect the surface and make the next cleanup easier.

Mold & Mildew Questions, Answered By Boaters

What's the difference between Boat Juice Interior Cleaner and Mildew Stain Remover? Interior Cleaner is your everyday wipe-down as it cleans and lays down UV protectant on vinyl and upholstery, but it's not built to fight an active mildew outbreak. Mildew Stain Remover is the dedicated formula for that job. It doesn't include UV protection, so follow up with Interior Cleaner once the stain is gone.

Will this get rid of really old, deep-set mold stains? It's built to tackle stubborn, baked-in mildew and mold, including black mildew, and most active stains lift with one or two applications. Fair warning from one boater to another: if mildew has been sitting for a long time and has worked its way deep into cushion foam or fabric fibers, not just the surface, a spray-on cleaner can lift the surface growth but may not fully restore fabric that's already discolored underneath. The best move is to catch it early and wipe down regularly so it never gets that far.

What surfaces is it safe on? Vinyl, upholstery, cushions, plastic, marine carpet, foam flooring like GatorStep, and canvas or boat covers. As with any stain remover, spot test on delicate or unfamiliar fabric first.

Do I need to scrub, or is spray-and-wipe enough? Spray, wait 1-2 mins and wipe. Light scrubbing helps on tougher, more set-in spots.

Will it damage stitching or seams? No, it's tough on mildew but safe on marine-grade stitching when used as directed.

Does it smell like bleach or chemicals? No, it's a Mango Tango scent, so cleanup smells like the sandbar, not a hazmat drill.
