How to Clean a Pizza Stone (No Soap, Minimal Water)
To clean a pizza stone, let it cool completely, scrape off burned bits with a bench scraper or plastic spatula, then spot-scrub stubborn spots with a baking-soda-and-water paste and a stiff brush. Use as little water as possible, wipe with a barely damp cloth, and air-dry fully before storing. Skip soap and soaking on traditional porous stones — they absorb detergent and moisture, which can leave soapy flavors, mold risk, or cracks. Dark oil stains are normal seasoning, not failure.
Why pizza stones are different
Unglazed ceramic and cordierite pizza stones are porous. They drink water and cleaning solutions the way a cast-iron skillet holds oil. That is why manufacturer-style care (and guides from sources like The Kitchn and Fine Cooking) centers on dry scraping first, minimal water, and no dish soap on unglazed stones. Thermal shock matters too: cold water on a hot stone can crack it.
Glazed stoneware is different — a sealed glaze can often take mild soap. When the label is unclear, treat the piece as porous and skip soap.
What you need
- Bench scraper or plastic spatula (not a sharp metal knife that gouges)
- Stiff nylon brush or dedicated stone brush
- Baking soda
- Non-shedding cloth
- Patience for full air-drying
Routine cleaning after pizza night
- Cool completely. Leave the stone in the oven with the door cracked or on a heat-safe rack until it is safe to touch.
- Scrape dry. Remove cheese, crust, and ash with the scraper. Most of the job is mechanical.
- Spot paste only where needed. Mix roughly equal parts baking soda and water into a paste (or slightly thicker for stuck spots). Scrub stained areas with the brush.
- Wipe sparingly. Use a barely damp cloth to lift paste — do not rinse under a running faucet or soak in the sink.
- Dry fully. Pat with a dry cloth, then air-dry several hours or overnight before storing or the next bake.
When the stone looks black
Absorbed oils darken porous stones over time. That patina is expected and does not make pizza taste burnt by itself. You cannot (and should not try to) scrub a well-used stone back to factory white.
For stuck-on carbon:
- Cool, scrape, and use a thicker baking-soda paste.
- If residue remains, many makers and cooking sites suggest a heat-cycle clean: place the empty stone in a cold oven, heat to a high baking temperature commonly used for pizza stones (often in the 450–500°F / about 230–260°C range), hold long enough to carbonize crumbs (often up to about an hour), then cool and brush. Ventilate — it may smoke lightly. Always stay within your stone and oven manufacturer limits; do not invent a temperature above what your manual allows.
- Never quench a hot stone with water.
What happens if you use soap
Soap soaks into pores and can off-gas into the next pie. Soaking traps water that may promote mold or steam-crack the stone on the next heat-up. Dishwashers are almost always wrong for unglazed stones for the same reasons.
Pampered Chef and similar unglazed stoneware brands generally tell you to scrape, use hot water without soap if needed, and baking-soda paste for stubborn spots — not a soapy soak. Follow your specific product’s care page when you have it.
Seasoning note
“Seasoning” on a pizza stone is mostly polymerized oils and use, not a cast-iron polymer layer you build with flaxseed rituals. Do not oil a stone heavily hoping for nonstick magic — excess oil smokes and stains. Prevent sticking with parchment (if your recipe allows), a dusting of semolina or cornmeal, or a well-heated surface.

Frequently asked questions
Can I wash a pizza stone?
You can spot-clean; you should not soak or soap a traditional porous stone.
Is mold on a damp-stored stone dangerous?
Discard or deeply dry and scrub if you see mold from poor storage. Prevention is better: store only bone-dry stones in a dry cabinet.
Why did my stone crack?
Common causes: thermal shock (cold water or a cold stone slammed into a screaming-hot oven without gradual heat), manufacturing defects, or side impact. Preheat gradually when your maker recommends it.
