To care for a marble countertop, seal it regularly and dust weekly with a microfiber rag. Marble has more pores than granite, and it dents more easily as well, Therefore, scratches and pits tend to show up more, and the shiny finish dulls more quickly.Continue Reading
Apply a pH-neutral cleanser manufactured for stone with a damp rag to clean residue from the counters. Avoid regular cleansers that have abrasive chemicals, which damage the stone over time. Remove spots from citrus fruits, tomatoes and other acidic foods quickly, as they eat away at marble.
Use a soft microfiber cloth to clean the dust off your marble countertop at least once a week. Do not use a brush to dust, as the bristles are abrasive against the stone surface. Remember accumulated dust, combined with water and other liquids, forms spots on the marble, so keep your counters free of dust.
Pay attention to the way water acts on the marble, and apply a fresh round of sealant each time the water stops forming beads when it splashes on the marble. Remember sealant also keeps stains from setting in and makes the finish on the marble countertop last longer.
