Maintenance of Natural Stone Natural stone tops are surprisingly resilient to stains and scratches. However, as a preventative measure, any spills on stone surfaces should be wiped up within a reasonable amount of time. Do not let liquid reside on the surface overnight. Natural stone is most prone to staining by oil and acid, so be sure to blot these spills up as soon as they happen. Follow up by cleaning the stone with a mild nonabrasive soap and water.
