Spots on oak tabletop
Hi, I have never refinished any stained furniture, and would appreciate advice. I have sanded away glossy finishes and painted furniture before, but do not want to paint this piece. I purchased a dining table that will be used daily in a breakfast room. I am certain that the top is solid oak, not a veneer. The top has a few scratches that do not bother me, because it will surely get more. But there are a couple of round spots that I would guess resulted from hot dishes being set without protection underneath. They are lighter in color than the other wood. How could these be removed? (I realize that I would have to do the entire top, not just the spots.) Also, what would be a good choice to finish with, that would protect the table from water rings, etc., if used without a tablecloth? Also, if I decide not to remove the spots, would I need to apply anything to protect the top for daily use? I would describe the finish now as a low gloss, which is pretty. Thanks for your help.
