How to Clean Pizza Stone

The Golden Rule: Never Use Soap on a Pizza Stone

Before anything else, understand this: pizza stones are made of porous ceramic, cordierite, or clay — materials that absorb liquids. If you use soap or dish detergent, the stone will absorb it and release a soapy taste into your next pizza. Similarly, never submerge a pizza stone in water or put it in the dishwasher. The cleaning approach for pizza stones is fundamentally different from other kitchen items.

Why Pizza Stones Look Dark (And Why That's Okay)

A well-used pizza stone will darken over time as oils and food residue season the surface — similar to a cast iron pan. This dark patina is normal and actually improves the stone's non-stick properties. You're not trying to make it look new; you're just removing loose debris and burnt-on food that could affect flavor.

What You'll Need

• Pizza stone brush or scraper
• Plastic or metal scraper
• Warm water (minimal)
• Stiff-bristle brush
• Baking soda (for stubborn spots only)

A dedicated pizza stone brush and scraper combo is the ideal tool — the stainless steel head scrapes off carbonized residue while the brush sweeps away loose debris. For stubborn spots, a paste of baking soda and water (used sparingly) can help lift stains without soap.

Routine Cleaning After Each Use

Step 1: Let the Stone Cool Completely

Never clean a hot pizza stone — thermal shock from water or even cool air can crack it. Allow it to cool in the oven with the door open, or on a heat-safe surface, until it reaches room temperature. This can take 1–2 hours.

Step 2: Scrape Off Loose Debris

Use a pizza stone scraper or a stiff plastic scraper to scrape off any stuck-on cheese, toppings, or carbonized food. Work gently — you're removing debris, not trying to strip the surface.

Step 3: Brush Away Residue

Use a stiff-bristle brush (dry) to sweep away all loosened debris. Brush over the entire surface, including the edges.

Step 4: Wipe with a Barely Damp Cloth (Optional)

If there's still residue after brushing, wipe the surface with a cloth dampened with plain warm water — no soap. Use as little water as possible. Allow the stone to air dry completely before storing or using again. Never put a damp stone in the oven — the steam can cause cracking.

Deep Cleaning for Stubborn Stains

For Burnt-On Food

Make a paste of baking soda and a small amount of water. Apply it to the stained area only and scrub gently with a stiff brush. Wipe away with a barely damp cloth. Allow to dry completely.

For Grease Stains

Grease stains on pizza stones are largely permanent — the porous surface absorbs oil deeply. The best approach is to place the stone in a 500°F (260°C) oven for 1 hour. The high heat burns off surface grease and carbonizes it, making it easier to scrape away once cool.

For Odors

If your stone has developed an off smell, the high-heat burn-off method above is the most effective solution. You can also sprinkle baking soda over the surface, leave for several hours, then brush away.

What NOT to Do with a Pizza Stone

• Never use soap, dish detergent, or any cleaning product.
• Never submerge in water or put in the dishwasher.
• Never put a cold stone into a hot oven — always heat it gradually with the oven.
• Never use metal utensils to scrape aggressively — they can gouge the surface.
• Never clean a hot stone with water — thermal shock can crack it.

How to Store a Pizza Stone

Store your pizza stone in the oven on the lowest rack — many pizza enthusiasts leave it in permanently. It acts as a heat sink that stabilizes oven temperature and improves baking results for everything, not just pizza.

Final Thoughts

Cleaning a pizza stone is more about what you don't do than what you do. No soap, no soaking, no dishwasher — just scraping, brushing, and occasional high-heat burn-offs. Treat it right and a good pizza stone will last for decades.
