There are lots of good inexpensive rust stain removers to choose from.solutions containing, oxalic acid and/ or phosphoric acid work well, or a solution of 15% hydrochloric (muriatic) acid in water also works well. Neither will hurt your deck. Around here we can get a no name toilet bowl cleaner that contains 23% hydrochloric acid and I use that to clean rust on the deck that comes from my anchor chain. Apply the stuff only where needed and let sit for about 10-15 minutes and then rinse well with water. If you're not happy reapply and rinse again. Also I find a solution of trisodium phosphate (TSP) works well as a general deck cleaner but not so good for rust stains. I do my deck every spring before launch with the TSP solution and I remove any rust stains with the toilet bowl cleaner before the general wash down with TSP. I have used these solutions to clean gel coat decks and now also on the deck of Alianna which has been coated with International Perfection 2 part polyurethane paint. I always do the deck cleaning before shining up the hull to avoid possible degradation of the shine with deck wash down water, I think most people would clean from the top down for that reason.

I had someone working (well that claimed to be working on my boat) on my boat doing some wet sanding and setoling my hand rail extra. Two problems, one he told me that he had removed all the tape that he put on the gel to protect it...NOT so when I removed the tape there is some residue of glue etc on the gel. The boat has been hauled and is on the cradle in the shed but there will be all kinds of 'stuff' in the wind that will get on this residue and damage the gel. I think he thought that I would miss it because the boat was in the hanger...and secondly he left tools and the setol can (metal) on the deck and obviouly during a rain storm and stained the decks with the metal so I now have a metal ring on my deck in two places and the outline of the screw driver that he probably used to open the can. Believe it or not this person came highly rated...whatever! Is there something that I can use that will remove these stains? Many thanks!

Clean the decks, buff the topsides and apply New Glass, refinish the mast with white Imron, sand, fair, and repaint the bottom. The boat was looking really nice and ready for relaunch - until a few days ago. A young yahoo decided to sand the bottom paint off his old boat, and the black sanding dust ended up on the recently painted - but not fully cured - mast. Reportedly it was ablative paint and why he didn't have the yard take it off with the pressure washer when the boat was hauled I cannot say. Anyway, the mast has been wet sanded to remove the imbedded black stuff and repainted. Yesterday when they went to step the mast at the yard they discovered that the deck is also looking pretty bad. The black sanding dust has bled into the gelcoat and - apparently because of the effects of sun, heat, and morning dew - there are purple-ish blotches that look like bruises on the recently pristine deck. My buddy is trying to clean the decks without screwing up the work already done on the bottom and topsides. Normally he would use On and Off on the deck, but we both suspect that the oxalic acid runoff from the decks will ruin the New Glass and the Trinidad Pro bottom paint. So here is the C&C related part of this message: We want to draw on the expertise and experience of the list before attacking the deck. Can anyone recommend a cleaner or a method to clean the deck without screwing up the shiny topsides?
