Cultured Marble Countertops are polished to a high gloss, although they can be ordered in more of a matte or flat finish if you're searching for that style or maybe presentation. General cleaning simply requires wiping the surfaces with a slightly damp cleaning cloth to clear out dirt and soiling. In cases of severe marble etching, a restoration or even refinishing kit could be needed. Restaurant countertops are actually non natural and somewhat porous, disinfecting them with store bought cleanser usually gets rid of virtually all germs and bacteria. An additional benefit of marble is it's waterproof. Resealing them when a year with a commercial sealant is recommended.
