[header] How to clean a pizza stone [title] Let your stone completely cool off. [step] Before handling, you should allow it to cool off in the oven for an hour, otherwise there's a possibility it could crack, especially if you expose it to cold air or water. Make sure that your stone cools to room temperature before you attempt to clean it. 
[substeps] If you must handle it when it is hot, use heat-resistant gloves so you do not burn yourself. Be sure any surface it is placed on is heat-resistant.
