After sitting in the water on and off this summer the boat has a little yellow haze at the water line. Brought the boat home last night from the cabin to trade in or sell. I am dropping the boat off at a dealer tomorrow and want to wash the boat up.
My question is this: what will take the yellow off the white gelcoat? I know obviously hull cleaner with acid will. Looking for something I can buy today and won't hurt the painted trailer or my blacktop driveway? Idea's? Will vinegar do it? It's not bad just a faint yellow color, not even consistent. Mostly along the waterline.
