Removing "wetness" from old oak floors
My husband and I bought a 100-year-old farmhouse that needs a total rehab. The original oak floors are in good shape and look great after a thorough sanding. We removed a couple of walls on the 2nd floor and the oak flooring underneath is stained with some kind of urine (bat?)and smells awful. When the humidity rises, the floor actually gets damp and the smell is even worse. I have sanded off a good portion of the surface, but the wetness keeps coming back. Is there a product that can kill the stain without damaging the oak? I would hate to have to rip it all up when the condition is still so good.
