My mom's old DR table has a spot on it. My son wants to use it, but we are just not sure how to handle this problem. You will see the spot in the pics as well as a chipped spot. I think the table is mahogany, but not certain. Any ideas on how to handle the spot? Would it be advisable to sand the top down and refinish? BTW, the table is about fifty years old.
