I’ve come across a wood floor that has blackened splotches underneath the finish. What’s the best approach to take to get rid of these stains. The floor has been sanded and the stains are still there. My customer wants a nateral finish. Is there any reliable method of bleaching? There is also an unmistakable odor of urine. My guess would be that Muffy wasn’t all that well trained. I appreciate any help available. Thanks!!

If the spots did not come out in the normal course of refinishing, then you will have to remove the stained boards and replace with new. Apparently, the owner did not want to pay the floor contractor the cost to remove them at the time of the refinish. Bleaching does not work. GW
*Urine contains just about everything you need to ruin wood and to change your mind about pet ownership.Even if you could bleach the stain, the fibres are damaged and will not recover enough to match.I'm with Greg, replace.
*I agree with Greg, these aren't like normal stains, the discoloration is produced by a chemical reaction and usually penetrates right through the board. One thing to watch, a small, faint stain will become far more obvious once the coating goes on. If in doubt as to whether it needs to be removed, wipe it over with a wet rag and see how it looks then.
*I'd have to suggest in replacing the affected areas with existing, carefully taken from closet areas, if possible or areas unnoticable. New will look new and the repair will always be visible.
*Been there, done that - replace the wood.Jeff
*Yep replace the wood. There are sources that carry used flooring to match the grain and coloration of the era. Closets or carpeted(permanently)areas work too. It's fairly easy to plunge cut,remove and feather in new pieces.David
*Been there, done that. I had to replace the wood. If you have a closet to borrow from that's fine, but be careful because a patch always looks like a patch. If the room isn't to large replace the whole floor, if not then weave in old boards with new one at a ratio of two old to one new. This blend will be satisfactory and will not catch the clients eye(much). I have seen patch jobs with new wood and the clients HATE them, because they jump out like a bad sore. If you are good with matching stains then that is another solution, I'm not so its easier for me to replace it.
