Ive used Oxalic acid on boats to remove stains prior to refinishing the brightwork
Also does wonders on rust stains
The commercial wood cleaners bought in hardware stores have Oxalic as their active ingredient
Its a fierce oxidizer - so shipping by air is hard if you are buying ebay etc ...ace sells small quantities but pricey (10 - 15 for 8 ounces if I remember right)
We buy it in bulk for the boats from an old school supplier on the mainland - about 5 dollars a pound
West Marine sells it in small quantities as well
