Sno-Bol and the "iced tea" stain

Left my boat in the lake over the weekend and the stain was considerable. So I searched and found the tip to clean with Sno-Bol toilet bowl cleaner. It by far, works better than anything I have ever tried. $3.19 for a container...$1.00 for some sponges. It contains Hydrochloric Acid so you do want to be careful, but it worked almost instantly. I worked my way along the boat sponging it on. I later went along with soapy car wash and scrubed it down and then sprayed it off with the hose. Gleaming white again!! Follow up with wax and we'll see how it works this coming weekend.
