oxalic acid can remove some stains from certain types of bare wood- wood that does not have any finish applied.

If your wood has a finish, the water mark is in the finish, not the wood. This older thread might help with some ideas: http://forum.doityourself.com/showthread.php?t=276158

'Water marks' IN the finish show white. These can often be removed by a light sanding and/or steel wooling to remove the top layer of finish where the moisture has settled.

Water marks that have penetrated the finish and affected the wood show black. The piece must be stripped before using the oxalic acid.
