Hi, I'm going to sand and refinish a hardwood floor that has some dark stains from pet urine. Even after sanding, they remain darker than the rest of the floor. Would bleach help lighten them up to match the rest of the floor? Thanks, Henry
Bleach would lighten them up, however, getting them to match the rest of the floor would be luck of the draw. Doing it right would require you to chisel those boards out and replace them prior to sanding. If they're stained like that, they're damaged anyway, why would you want to keep them?

Save the aggravation. Just use a small rug.

Yeah, like remove the staining...

Oxalic acid is your friend here. The stains are caused by tannins in the wood darkening. Buy some deck cleaner (check the label to be sure it contains oxalic acid) and soak the area. Repeat until the stain is gone. I've even used it on finished floors. It won't change the unstained area at all. -- Doug
The OP may be in the same circumstances as myself. I have mid 1950's floor. It is solid oak 3/4 inch thick by two inches wide. Top nailed, not tongue and grove.
Just try to find 2 inch wide 3/4 inch thick oak (preferably red oak). If you do find it, please post the link.
Wouldn't a good drum sanding take care of most of this? And then use bleach if needed?
