“As a Captain, keeping my boat sparkling clean is essential, especially since mold loves to sprout on the seats! I struggled for years to find a product that actually worked without damaging the fabric or stitching. They all left traces of mildew/mold behind. Even scrubbing with a brush and a Magic Eraser wouldn't do the trick.
Here's the magic: I applied Dot, let it sit for a minute, then rinsed it off. And that's it! The mold was gone! My seats and cushions looked brand new, ready to impress my customers on breathtaking cruises through the Naples Bay.
Dot is now my go-to weapon against boat mold. It's effective, gentle, and leaves my boat looking its absolute best. If you're tired of battling mildew/mold, give Dot a try – you won't regret it!”
