My boat has a hydraulic swim platform. This past weekend, we had the platform lowered into the water most of the day. The water was darker than normal, stained with tannins flowing down the rivers to the Gulf. The tannins stained the gel coat on the platform "tooth rot yellow". It doesn't show up all that well in the attached photo, but you can see the difference in color from the stationary platform (where my feet are) and the hydraulic platform. It's very obvious in person. I have cleaned it twice with West Marines concentrated non-skid cleaner, and once with bleach, but it's still yellow. What can I use to get it back to white? Thanks, all.
