Looking for some advice to remove black stains out of red oak.
A friend asked if I could repair a split in a solid oak round table top. The table top was also warped. I did what I could to clean up the split and reglue the top, but now I'm trying to refinish the top.. The previous finish was badly cracked + flaking and black stains were left where several plants had been placed.
Am I stuck with the stains????
