Stones are naturally porous. They tend to absorb stains and water, both of which run rampant in kitchens. It’s important to seal your stone every couple of years to protect against grease and grime. Even then, some stains will be hard to remove. Some homeowners just don’t have the time or patience for this added maintenance. Devoted cooks might want a backsplash that’s better equipped against staining.
You also have to be selective with your cleaning products. Natural stone can discolor when exposed to certain chemicals. Warm water or a special stone cleaner will usually do the trick, but always check manufacturer guidelines before you bust out your cleaning supplies.
