In this FS seminar, FS boating forum moderator Dan McCarthy explains how to remove tannic stains from your boat’s hull.
If you leave your boat in the water for extended periods of time, or even just run in dirty waters, you’ll find yourself dealing with a stubborn yellowish stain from the waterline down. Freshwater and soap won’t even make a dent in removing this discoloration. Having the right cleaner will make the job painless. Star brite produces an “Instant Hull Cleaner” that makes removing these stains effortless. Just pour the product on a rag and wipe the stained area. Of course, there are some important precautions that must be made.
