Question: I have Marble Natural Stone floors in the kitchen. Some vinegar got on the floor and now we have a light spot. I believe that it is the sealer (polyurethane coating?) that got discolored. What is the best way to get rid of these dull spots and bring the normal shine back?
Answer: When acid (vinegar) comes into contact with marble (calcium carbonate), it causes a chemical reaction. The result is called etching. Natural stone sealers penetrate the stone and do not prevent this natural reaction. If you do in fact have a polyurethane coat on top of your stone, then you have a different problem altogether. If the stone is etched, we can refinish it.
