What special care does stone require?
…Marbles should be sealed once or twice a year. Granites should be sealed once a year.Note,using a sealer does not make the stone un-stainable. It simply fills the pores in the stone and make the staining process slower, thus giving you more time to clean a spill before a stain sets in. Otherwise, the usual clean regularly, don’t use acidic or abrasive cleaners that will dull the finish over time.
