I use Muriatic acid diluted to about 15%. Spray it on with a 1 gallon all plastic pump sprayer. It usually takes a few times to remove all the scum. Pressure wash off each time. I buy it by the gallon for about the same price as other name brand acids in the litre jugs.

Some of the boats i do sit in the water all summer and haven't been cleaned in years. I have tried a few OTC acids and they didn't work any better and some worse than the Muriatic acid.

These products are not in my area, so i haven't tried them, but have read they are good.
On and Off is 23% Hydrochloric and 4.5% Oxalic acid i do believe. Another good product is Captain Phab, it is a mix of acids in gel form.

Salty, that's great advice. I like the idea of the acid to remove the oxidation. I can't imagine how long it would take to try to take that off with compound! You'd spend days getting to the same point, I am sure. I'll definitely look into the Starbrite product.

Thank you very much.

Not sure you totally understood. I used the acid to remove water scum below the water line. Not to remove oxidation. That was done by machine and the Star-Brite product.
