Clean the stone

Burn it off, brush it cold, flip it

The Essentials Guide and Ooni's help centre. Colour changes are normal and do not affect cooking.

1. Burn it off: run the oven at top heat for about 30 minutes, or let the next preheat do it.
2. Let the oven and the stone go completely cold before you handle it.
3. Brush off flour with the bristle side of the Ooni brush, flip to the scraper for burnt bits, and sweep them out of the mouth.
4. For stubborn marks, turn the stone over: the heat cleans the underside next time.
5. Never use water, soap, cleaning products or a dishwasher on it.
