Most of the time when a customer asks us why their natural stone countertop is not shiny anymore, the dullness is not a problem with the stone, but is caused by a filmy buildup of some kind on the surface. This comes from cleaning granite or other natural stone countertops with water and dish soap or some other inappropriate cleaner that leaves a residue. Switching to a pH neutral cleaner specifically designed for use on natural stone will fix this problem, though it may take several cleanings to do so. In rare cases, there are other, less benign reasons your countertops have become dull, which could require professional restoration. So, if a neutral stone-safe cleaner does not resolve the dullness or you would like a consultation before taking any action, please don’t hesitate to call us. We’ll help you figure out the best course to take to get your countertops back to the shine you love.
