Pizza stone stains? Cool fully, scrape gently and rinse without soap
For Weber pizza stones, cool completely, gently remove stuck-on food with plastic and rinse with water. Avoid detergent, soaking, dishwashers and thermal shock.
Pizza stones may darken with use. Weber describes this discoloration as normal and not necessarily harmful to performance or flavor. The instructions here follow Weber; always prioritize your own model's manual, particularly for coated stones.
