Never clean a pizza stone with soap. Only clean your pizza stone after it has completely cooled. Putting a hot stone into tepid water will weaken its structural integrity and can cause small fractures that could lead to eventual breakage. As this stone is not glazed, it is not sealed in any way, so food and oils can seep below the surface. Always scrape off all spilled or cooked food with a stiff brush, scrubbing pad, or plastic scraper, and simply wipe the surface of the stone with a damp cloth. Make sure the stone is completely dry before seasoning and using again.
