How to Clean Ooni Pizza Oven Step by Step

How to clean Ooni pizza oven parts comes down to three steps from Ooni’s own guides: let it cool fully, brush out the debris, and burn off stuck food at top heat. Ooni’s Pro guide says a run at top temperature does most of the work, so routine cleaning stays quick. Models differ in fuel and parts, so check your manual before you try anything beyond these basics.
Wood, charcoal, pellet, gas and electric Ooni models need different care in some places. The steps on how to clean Ooni pizza oven models cover the routine that applies across the range and points out where the fuel type or model changes the steps.
How to Clean Ooni Pizza Oven After Each Cook
For how to clean ooni pizza oven after each cook, wait for the Ooni to cool completely, then brush out loose debris with the Ooni Pizza Oven Brush. Ooni’s cleaning guide says to brush sideways and back-and-forth, then sweep the debris out through the front.
Timing matters more than effort. Ooni’s guides say to clean only once the oven is fully cool, so the brush does not move hot ash or soot around while it is still burning.
- Let the oven cool completely before you touch the stone or the interior.
- Brush the stone with the Ooni Pizza Oven Brush, sideways and back-and-forth.
- Sweep loose debris out through the front opening.
- Wipe the inside with dry paper towels, not water.
Ooni’s Pro essentials guide adds that there is no need for elbow grease after a normal cook. A run at top temperatures does most of the work for you, so a heavy scrub is rarely needed.
How to Clean the Pizza Stone on an Ooni
How to clean Ooni pizza oven stones takes the least effort: the stone is a cordierite baking board, and a run at top temperature for about 30 minutes burns off most food stuck to it. Let the oven cool before you touch the stone, then brush it clean.

The Ooni Pro essentials guide describes the stone boards as custom-made from cordierite. Stone care is the part most people ask about.
Burn-Off at Top Temperature
Ooni says to run the oven at top temperature for about 30 minutes when food sticks to the stone. The Ooni Pro is rated for up to 932°F (500°C), according to its essentials guide.
Ooni also states that the stone changing color is normal. A darker stone after months of cooking does not mean it is damaged, so focus on removing loose debris rather than restoring the original color.
Hand Washing the Stone
If you prefer to wash the stone by hand, use warm water, as Ooni describes. Ooni’s Pro guide then says to dry the stone in a conventional oven for at least 2 hours at 140°F (60°C), and it notes that the stone is not dishwasher safe.
Once the stone is cool, flip it over before the next cook. Ooni says the top heat will clean the underside as you cook, so you do not need to scrub both faces every time.
How to Clean the Ash Tray and Fuel Area
To see how to clean Ooni pizza oven ash on the Karu 12 or Fyra 12, let the oven cool completely before you remove the fuel tray. Dispose of the cooled ash in a fire pit, a compost pile or another eco-friendly option.

For the Karu 12, Ooni’s blog says to brush excess soot from the tray, then wipe it with a dry paper towel. Keep water out of the metal interior of the oven as well.
- Wait until the oven is completely cool.
- Remove the fuel tray and empty the cooled ash.
- On the Karu 12, brush excess soot off the tray with the Ooni brush.
- Wipe the tray with a dry paper towel before you return it.
Some soot is normal with wood and charcoal. Ooni’s Pro guide says a light layer can appear during a cook, so wipe it away once the oven has cooled rather than during a hot cook.
Cleaning by Fuel Type: Wood, Charcoal, Pellet, Gas and Electric
How to clean Ooni pizza oven models by fuel depends on what builds up inside. Wood and charcoal leave soot, pellet ovens can leave oily residue, and gas and electric units follow their own manufacturer rules for safety and cool-down. For the electric model, our Ooni Volt 2 manual guide covers setup, cleaning and safety.
Ooni’s Pro guide lists wood, charcoal, wood pellets and gas as fuel options for the same oven. It gives a preheat time of 20 to 30 minutes for each of these, which is useful when you plan a cleaning run.
| Fuel | What Ooni says | Cleaning focus |
|---|---|---|
| Wood | Preheat 20 to 30 minutes; Pro up to 932°F (500°C) | Brush soot from the fuel area once cool; wipe glass when cool |
| Charcoal | Preheat 20 to 30 minutes; Pro up to 932°F (500°C) | Cool fully, then brush out ash and soot |
| Wood pellets (Fyra 12) | Oily residue can build on the hopper or chimney | Scrub with soap and warm water, then dry at once |
| Gas | Preheat 20 to 30 minutes; estimated 482°F to 932°F (250°C to 500°C) | Follow the gas burner manual for gas type and safety steps |
| Electric (Volt 12) | Cool for over 90 minutes before cleaning or storage | No liquid, food or cleaning agents on the stone |
For the Fyra 12, Ooni’s blog says oily black creosote on the hopper or chimney can be scrubbed with soap and warm water, then dried right away. It also recommends Ooni wood pellets only, airtight pellet storage and an open chimney baffle while cooking.
For gas models, this guide does not add steps beyond the manufacturer. Ooni’s Pro guide tells gas users to refer to the gas burner manual for the gas type and its instructions.
How to Clean the Glass Door and Exterior
How to clean Ooni pizza oven glass is simple: wipe the glass door with a dry paper towel only after the Ooni has cooled completely. Ooni warns that water on warm glass can cause damage, so keep the door dry while it is hot.
For the outer shell, wipe with a damp cloth and dry it straight away. Ooni’s blog advises against abrasive products and harsh chemicals, and its Pro guide suggests a stainless steel cleaner on the outer shell.
The Karu 16 glass door has its own cleaning method in Ooni’s blog. For the stone in particular, a separate guide on how to clean a pizza stone goes deeper. Mix one part vinegar with three parts water, let it sit for five minutes, scrub with the coarse side of a sponge, then rinse and dry completely.
What Not to Do When Cleaning an Ooni
Never pour water on an Ooni to cool it or put out the fire, because Ooni says this can cause damage and personal injury. Avoid abrasive products on every part of the oven.
- Water on the hot oven, which Ooni says can damage it and cause injury.
- Water on the metal interior of the Fyra 12, Karu 12, Karu 16 or Karu 2.
- Any liquid, food or cleaning agent on the Volt 12 stone.
- Abrasive products and harsh chemicals on the exterior.
- A dishwasher for the stone boards.
Soap appears in only one Ooni instruction here: scrubbing oily creosote from the Fyra 12 hopper or chimney. For everything else, Ooni’s guides use dry paper towels inside and a damp cloth on the exterior. If you also own a Roccbox, cleaning a Gozney Roccbox follows different rules.
Storing Your Ooni Between Cooks
How to clean Ooni pizza oven parts well includes storage: store the Ooni indoors for long periods, keep the stone boards warm and dry, and make sure the oven is completely dry and cool first. Ooni’s blog also mentions waterproof covers for wet weather. Owners of the Fyra 12 can find setup and care details in the Ooni Fyra 12 manual guide, and Koda owners can use how to clean the Ooni Koda 16.
Moisture is the main storage risk. Ooni asks that the oven be dry and cool before it is put away, and that the stone stays warm and dry when the oven is not in use.
Ooni’s Pro guide also says to use the Sizzler Pan for meat and vegetables, and to cook pizza and dry bread-based dishes directly on the stone. Keeping food residue off the stone means less cleaning later.
