It’s easy to clean Ooni pizza ovens. Simply run your oven at full temperature for 30 minutes. The high temperature will burn off any food and debris inside the oven, and on the baking stone.
Once the oven is completely cool:
The inside of the oven can be wiped down with dry paper towels.
For cleaning the outer shell of the oven, wipe down with a damp cloth and dry immediately. Avoid using abrasive cleaning products or those containing harsh chemicals.
If your baking stone is not as clean as you would like, we would advise trying to turn your stone over and cooking on the other side - you should find that the high heat will clean the stone for you.
Do not wash the stone or wipe it with a wet cloth as this will cause the stone to absorb moisture and crack when heated.
