Quartz and quartzite countertops have different maintenance needs due to their distinct compositions. Cambria quartz surfaces, being nonporous, are stain resistant, never need sealing, and are NSF-51 certified for safe food preparation. Simply wipe with warm water, a soft cotton cloth, and mild soap, if desired. To maintain its beauty, quartzite’s porous surface requires regular sealing and immediate cleanup of spills to prevent staining.
