Cleaning your Natural Stone

“After a summer filled with nonstop grilling fests, family gatherings, and just general outdoor fun and wear and tear, it’s important to properly clean natural stone around your home—whether it’s outdoor granite countertops, stone walkways, or patios—to prevent food, dirt, and oil stains from setting in and leaving permanent marks,” says James Freeman, chief operating officer of Colonial Marble & Granite.

DIY: Start by dusting off stone surfaces, because abrasive materials such as dirt or sand (carried home from weekend getaways) can cause damage. Avoid using harsh cleaning products on natural stone; instead, choose a gentle cleanser with a neutral pH (preferably without soap, which causes streaks and film) and a soft cloth. For a longer-lasting finish and better protection against stains and grime, consider applying a water-based penetrating sealer.
