Oxalic acid. Done as part of a strip and refinish. Be sure to rinse off the crystals after it dries and before you sand as the airborne version can be irritating.

I agree with the use of oxclic acid, it is best to neutralize the surface before finishing with a table spoon on baking soda in a cup of water ,wiping down the whole are that has been treated with oxcilic acid, and then using clear water to rinse that.
