Ooni pizza stone care: dry-brush, cool and skip soap or water
A porous pizza stone can absorb water and detergent. Ooni recommends dry cleaning after cooling and, when appropriate, controlled heat to burn off stuck-on food.
Do not soak a darkened pizza stone to make it look new. Ooni says discoloration can be normal; raised burnt debris is the issue. Cleaning and whether a stone can be flipped depend on the oven model, especially rotating-stone versions. Follow your specific oven manual before heat-cleaning or removal.
