I understand that rust stains and those brown stains we see just above the water line, at least we get them here in St. Margaret's Bay, are actually very fine particulates in nature and these small particles penetrate into the gel coat or paint. Getting rid of them requires more than elbow grease...it requires something that can get in there and dissolve those micron and submicron sized particles so they can be flushed out...when totally broken down into the constituents ions they are colourless in solution and acidic solutions or acidic pastes like oxalic, hydrochloric and phosphoric acids can dissolve these particles quite readily and presto...the stain is gone. Same for rust and manganese deposits that form in toilets that are flushed with water which contains iron and manganese particles like iron oxide hydroxide for example. Useless information maybe but it's a slow day here.

Google it for a million sources. I had always assumed it was just Oxalic Acid thickened up a bit, but there must be something else in there as it works a lot better than an Oxalic Acid paste. I just tried it on a lark, as I have a tendency to develop the worlds worst rust streaks down my transom from the mounting hardware on my Monitor and the teak shelf that sits underneath it. This stuff removed the streaks in less than 5 minutes after applying it with a paint brush and no scrubbing other than using the brush to keep the stain wet.
