How do you prevent dull spots, etching on marble and keep my marble polished and looking great
The short answer to that question is, you cannot prevent etching on any stone that contains calcite. However, if you ask 'How can I protect my marble from etching or dull spots' the answer is... Sealer.
It is very important, critical, vital in fact, to seal your marble every 6 months to a year, depending on how much the stone is used. Marble is like a sponge and will absorb everything! Sealing is the best way to protect against etching and staining on marble. Even though there is no way to prevent etches or stains on stone with calcite, sealing stone will add a protective barrier to the surface that helps you maintain the stone's appearance. Sealing your marble with a premium sealer like the Lustro Italiano premium grade sealer will give you a much longer time to clean up the spill. Also, it will protect against staining from wine, oil, mustard, ketchup, and other normal household items. Also, its important to know that if an etch or dull spot on marble has occurred, the acid that caused the etch has most definitely removed the sealer that was on the stone. That means that you Must reseal the stone where the etch was. But if it etched, there is a great possibility that the entire stone needs to be sealed.
