How Do You Clean Old Unfinished Marble Countertops?
Marble should be cleaned with a pH neutral cleaner in order to preserve its integrity and appearance. Traditional countertop cleaners are too acidic to be used on stone and can damage the surface. Clean any loose debris or dust from the surface of the countertop. Pour the stone cleaner into the spray bottle. Test the cleaner on a small, inconspicuous part of the countertop. If it stains or discolors the marble in any way, contact the manufacturer or retailer. Spray the stone cleaner liberally across the surface of the countertop. Wipe the surface with the sponge in circular motions until the countertop is cleaned. Repeat as necessary.
