It's a common problem for boaters: Your boat sets in the water for just a short period of time and when you pull it out there's a yellow water line. We get the same yellow water line after our boat sets in the Black River, South Haven Michigan (our home port) after just a few days. We also hear this same issue from boaters all across the country. That's why we developed a biodegradable hull cleaning product specifically designed to remove the yellow water line stain from fiberglass boat hulls, the Bio-Kleen Oxidation Remover.

Check out this short video below as the Bio-Kleen Oxidation Remover is sprayed onto the yellow water line stain and the stain instantly disappears. It really is that easy and works that fast.
