If you own a commercial pizza oven—whether it’s a GAM, Paramount, Atlas, or other professional brand—one of the most important parts of your oven is the stone deck (or baking stone). This surface is responsible for giving pizzas their crispy, authentic base and ensuring even cooking. To keep your oven performing at its best, it’s essential to know how to properly clean and maintain your stone.
Why Is Pizza Stone Care So Important?
-
Longevity: Stones are considered consumable parts, meaning they can wear out over time. Proper care extends their lifespan.
-
Performance: A well-maintained stone delivers consistent heat and crisp results.
-
Hygiene: Regular cleaning prevents burnt residue, flour buildup, and unwanted odors.
How to Clean a Pizza Oven Stone
Unlike stainless steel or metal oven parts, pizza stones are porous, which means they absorb moisture and can be damaged if cleaned incorrectly. Here’s the right way to do it:
1. Allow the Stone to Cool Down
Never clean the stone while it’s hot. Let the oven cool completely to avoid burns or cracks caused by sudden temperature changes.
2. Scrape Off Debris
Use a stiff-bristled brush or a dough scraper to remove burnt cheese, flour, or crumbs. Do not use metal tools that can gouge the surface.
3. Dry Cleaning Only (No Water)
-
Never soak or wash your stone with water.
-
Because stones are porous, water will seep in, and the next time you heat the oven, it can cause cracks.
4. Burn-Off Cleaning Method
For tough, baked-on residue:
-
Heat the oven to its maximum temperature.
-
Let the stone “burn off” any leftover food particles.
-
After cooling, brush away the ash with a dry brush.
5. Avoid Chemicals and Oils
-
No detergents or soap: the stone will absorb them and affect food taste.
-
No oil seasoning: unlike cast iron, stones should not be oiled. Oil will soak in and cause smoking or bad odors.
Maintenance Tips to Keep Your Pizza Stone in Top Condition
-
Preheat Gradually
Avoid thermal shock by allowing the stone to heat up gradually with the oven, not by placing a cold stone into a hot oven. -
Rotate the Stone
Some ovens allow rotation of stones to ensure even wear and extend their lifespan. -
Brush After Each Service
A quick sweep after every shift in a commercial kitchen prevents buildup. -
Replace When Needed
Stones will naturally wear over time. If cracks become too large or heat distribution is uneven, it’s time to replace them.
Are Pizza Stones Covered Under Warranty?
Most manufacturers—including GAM, Paramount, and Atlas—class stones as consumable parts. This means they are not usually covered by warranty unless they arrive damaged or defective. Keeping up with maintenance ensures you don’t need replacements too often.
FAQs
1. Can I wash my pizza stone with water?
No. Stones are porous and will absorb water, which may cause cracking.
2. Why does my pizza stone look stained?
Stains are normal and don’t affect performance. Over time, your stone will “season” and darken naturally.
3. How long does a pizza stone last in a commercial oven?
With proper care, many stones last several years, even in high-volume kitchens.
Final Thoughts
Maintaining your pizza oven stone is simple but crucial. By following these cleaning and care tips, your oven will deliver consistent, authentic pizzas for years. Whether you’re working with a GAM, Paramount, or Atlas oven, a well-kept stone is the key to crisp bases, quick cooking, and customer satisfaction.
