A pizza oven maintenance routine keeps your oven performing well, looking good, and lasting for years. The good news is that pizza ovens are largely self-cleaning – the extreme heat burns off most residue. But there are a few regular tasks that make a real difference.
After Every Cook
Burn Off Residue
After you’ve finished cooking, let the oven run at full temperature for 5-10 minutes. This burns off any food residue, cheese, and flour left on the stone. Most ovens are essentially self-cleaning at high temperatures – the intense heat incinerates organic matter leaving just a light ash.
Brush the Stone
Once the oven has cooled to around 150-200°C, use a stiff-bristled pizza oven brush to sweep any ash and debris off the stone and out of the oven. Don’t try to clean the stone when it’s still very hot – the brush can singe, and the stone needs to be cool enough to handle safely.
Leave the Door/Opening Clear
Allow the oven to cool completely with the opening unobstructed. Trapping heat inside when cooling can cause thermal stress on some materials. If your oven has a door, leave it slightly ajar or fully open while cooling.
Monthly Maintenance
Clean the Exterior
Wipe down the outside of the oven with a damp cloth once it’s completely cold. For stainless steel exteriors (like Ooni and Gozney ovens), use a soft cloth and avoid abrasive cleaners that could scratch the surface. A small amount of washing-up liquid on a cloth works well for grease marks.
Check the Burner (Gas Ovens)
On gas ovens, check the burner ports monthly for blockages. Spider webs, debris, and insects can block the small holes in the burner, causing uneven heat or ignition problems. A wooden toothpick or a can of compressed air can clear blocked ports. Never use metal to clean the burner ports.
Check the Gas Connections
Inspect the gas hose and regulator for any signs of cracking, wear or damage. If you notice any damage, replace the hose before using the oven again. Apply soapy water to connections while the gas is running – if you see bubbles, there’s a leak that needs immediate attention.
Inspect the Pizza Stone
Check the pizza stone for cracks. Small cracks are normal and don’t affect performance. Large cracks that go all the way through may mean the stone needs replacing. Never put a cold stone into a very hot oven – always preheat gradually to avoid thermal shock. Read our full guide on how to care for your pizza stone.
Seasonal Maintenance
Deep Clean the Stone
A few times a year, heat the oven to maximum temperature and leave it burning for 30-40 minutes. This burns off any deeply embedded residue and effectively resets the stone. Let it cool completely, then brush away the ash.
Never use soap or water on a pizza stone. Water can cause the stone to crack when heated, and soap leaves a residue that will affect the flavour of your pizza. The high-heat burn-off method is all the deep cleaning a pizza stone needs.
Check and Replace the Chimney Cap (Wood Ovens)
On wood-fired ovens with a chimney, check the chimney cap for build-up of creosote or debris. A blocked chimney causes smoking problems and reduces draw. Clean with a chimney brush if needed.
Inspect Seals and Insulation
Check any door seals or insulation panels for wear. On Gozney Roccbox ovens, the insulation layer around the body should remain intact. On Ooni ovens, check that the legs and hinges are tight and functioning correctly.
Storage and Weather Protection
Use a Cover
A purpose-made cover for your pizza oven is one of the best accessories you can buy. It keeps rain, bird droppings and UV off the oven, significantly extending its lifespan. Most manufacturers sell covers designed for their ovens – they’re usually worth the cost.
Store the Pizza Stone Indoors in Winter
If you live somewhere with freezing winters, consider storing your pizza stone indoors during the coldest months. Moisture can get into a porous stone and expand when it freezes, potentially causing cracking. If the stone is staying outdoors, make sure it’s under a waterproof cover.
Disconnect Gas Canisters
If leaving the oven unused for extended periods, disconnect and store the gas canister separately. This is both safer and protects the regulator from weathering.
What NOT to Do
- Never use water to clean a hot pizza stone
- Never use soap or chemical cleaners on the stone
- Never use metal scrapers on the stone (they leave marks and can damage the surface)
- Never put a cold pizza stone directly into a blazing hot oven – always preheat gradually
- Never leave gas connected when the oven is stored unused for long periods
- Never use abrasive pads on stainless steel exteriors
Follow these guidelines and a good pizza oven will serve you reliably for 10 years or more. The investment in maintenance is minimal compared to the cost of replacing a well-loved oven.
