I'm helping my girlfriend remove carpet at her home. Underneath are the original hardwood floors. Home was probably built in the 50's. For the most part they are in excellent shape with just a couple water stains that will be covered up with plants/furniture/rugs. However when we got to the hallway carpet and ripped it up, the remains of the padding that had been crushed is stuck like a son of a b!tch to the floor. I'm wondering what I could use to remove this without damaging the finish. We tried a sample area in the closet and a buffer just overheated the finish and melted it off, sandpaper scratches too much. I'm wondering if there is a liquid similar to "goof off" or a bug and tar remover that might removed the crushed padding and not harm the wood's finish?
