Recently my apartment flooded. I own two unfinished oak bookcases which were on wet carpet and absorbed water into the base along the front and sides. There is a watermark and some greenish discoloration of the wood. One bookcase has about 1" of water staining and the other 3" +/-. Most of the damages is to the oak ply sides of the bookcase where the end grain was resting on the floor. Is there any way to remove the staining and watermarks from the wood? Sanding? Any sort of finishing techniques? A solvent of any kind? I’d like to restore rather than replace the bookcases if possible.
