All granites are porous; what typically harms the finish on granite are the harsh chemicals contained in soap, shampoo, perfume, and cosmetics, the minerals in hard water, household cleaning agents which are highly acidic or alkaline in nature; all foods and beverages are not neutral when measured on the PH scale, many of which contain citric acid as a preservative. The easiest way your stone looking amazing is avoid any bad habits that may damage it. Granite, marble, travertine, limestone, soapstone, quartz and solid surface are similar in many ways, but their differences require varying degrees of maintenance. If you utilize the granite counter top care and cleaning procedures that follow for all your countertops no matter what type of stone or surface you’ll eliminate most potential problems without ever having to think too hard about it or worry that you may be causing damage.
