Why would mayo, an oil-based goop, take water stains out of a finish? Just curious... I know you didn't invent the idea :-).

Mayo? Black laquered finish I am guessing it is pressed board or mdf and that really shiny stuff? Find a vase or something that looks nice sitting on the spot and live with it.

The buffet is a very old Chinese antique and I sure would like to know what to do about the spots. The wood under the lacquer is a hardwood --- probably maple. The spots are not in a place where a vase would look OK.

I suggest you call a proper restorer or refinisher, one who is familiar with Chinese laquer - if you have a real antique, it's not worth chancing ruining it to save a few dollars on DIY.

I would Google something like "antique black lacquer repair" and see what turns up. If it's a really valuable antique in otherwise good condition, it sounds like the stain may have caused a significant loss in its value. That's a shame. I would go for a good antique restorer so you can continue to enjoy it. Good luck.

Thank you all so much. I did find a person who restores antiques and the cost is way prohibitive. I can certainly live with some 7UP stains and will probably continue to enjoy this piece until it is given upon my death.

I love this forum and appreciate your help!
