A pizza stone is one of those kitchen tools that quietly turns you into the person who says, “Actually, homemade pizza is better.” It gives crust that crisp, blistered, pizzeria-style finish that makes frozen pizza feel like it needs a motivational speech. But after a few rounds of bubbling cheese, runaway sauce, and flour that decided to become charcoal, your beautiful stone may look less like cookware and more like an artifact from an ancient bread civilization.
Good news: a stained pizza stone is usually not ruined. In fact, some discoloration is completely normal. The goal is not to restore it to “brand-new showroom beige.” The goal is to remove stuck-on food, burnt crumbs, grease buildup, and unpleasant residue without damaging the porous surface. Cleaning a pizza stone is simple, but it is also easy to overdo it. Soap, soaking, harsh chemicals, and sudden temperature changes are the villains in this story. Baking soda, patience, and a humble scraper are the heroes.
This guide explains exactly how to clean a pizza stone, how to remove stuck-on food and stains, what not to do, and how to keep your stone working beautifully for years of crispy crusts.
Why Pizza Stones Need Special Cleaning
Most traditional pizza stones are made from ceramic, cordierite, or unglazed stoneware. These materials are porous, meaning they can absorb moisture, oil, and anything else you rub into them. That is why a pizza stone can pull moisture from dough and help create a crisp crust. It is also why washing it like a dinner plate is a bad idea.
If you use dish soap, the stone can absorb the scent and residue. The next time you bake, your pizza may come out with a faint “lemon-fresh countertop cleaner” flavor. Delicious? Not unless your topping theme is regret. If you soak the stone, trapped water can expand when heated and may cause cracking. If you scrub too aggressively with metal tools, you can gouge the surface.
The best cleaning method is dry or nearly dry: let the stone cool, scrape away food, brush off crumbs, use a damp cloth only when needed, and deep clean stains with a baking soda paste.
What You Need to Clean a Pizza Stone
You do not need a cabinet full of cleaning products. In fact, the shorter the supply list, the safer it usually is for the stone.
Recommended tools and supplies
- Plastic, silicone, or wooden scraper
- Nylon brush or pizza stone brush
- Soft microfiber cloth

Think of your pizza stone as a cranky but talented chef. Treat it gently, keep soap away from it, and it will reward you with excellent crust.
Step-by-Step: How to Clean a Pizza Stone
Step 1: Let the pizza stone cool completely
Never clean a pizza stone while it is hot. A sudden temperature change can cause thermal shock, which may crack the stone. Let it cool in the turned-off oven for at least two to three hours, or even overnight if you finished pizza night late and are emotionally committed to the couch.
This step matters for safety, too. Pizza stones hold heat for a long time. They may look harmless, but they can still be extremely hot after the oven is off.
Step 2: Scrape off stuck-on food
Once the stone is fully cool, use a plastic, silicone, or wooden scraper to lift off stuck-on cheese, crust, sauce, and burnt bits. Hold the scraper at a low angle and work gently. Do not attack the stone like you are chiseling marble for a museum.
For stubborn food, scrape a little, brush away crumbs, then scrape again. Dry debris often comes off in layers. If you try to force everything at once, you may scratch the surface or break off small pieces from the stone.
Step 3: Brush away crumbs and ash
Use a nylon brush or pizza stone brush to sweep away loose debris. A stiff nylon brush is strong enough to remove crumbs but gentle enough for most stones. Avoid metal bristles, especially on ceramic or unglazed stoneware, because they may damage the surface.
If you use your stone in an outdoor pizza oven, very high heat can turn residue into ash. Once cool, brush that ash away before storing or cooking again.
Step 4: Wipe with a lightly damp cloth
If dry scraping and brushing are not enough, wipe the stone with a cloth dampened with warm water. The key word is “damp,” not dripping. You want just enough moisture to pick up fine residue, not enough to soak into the stone like a sponge at a car wash.
After wiping, immediately dry the surface with a clean towel and then let the stone air-dry completely.
Step 5: Use baking soda paste for stubborn stains
For darker stains, greasy spots, or cooked-on residue, make a simple paste with baking soda and a small amount of water. A good starting ratio is about three parts baking soda to one part water. The paste should be thick enough to spread, not runny.
Apply the paste to stained areas and let it sit for 10 to 15 minutes. Then scrub gently with a nylon brush or cloth. Scrape away the paste and wipe with a lightly damp cloth. Repeat if needed, but do not chase every mark. Some stains are permanent, harmless, and part of the stone’s natural seasoning.
How to Remove Burnt Cheese from a Pizza Stone
Burnt cheese is the drama queen of pizza stone messes. It starts as a tiny bubble, escapes the crust, and somehow becomes a black fossil welded to the surface.
To remove burnt cheese, let the stone cool fully. Use a plastic scraper to lift the thickest pieces. If the cheese does not move, do not gouge it. Brush away loose crumbs, then apply a baking soda paste directly over the burnt spot. Let it sit for 10 to 15 minutes. Scrub gently with a nylon brush and wipe with a damp cloth.
If a thin dark mark remains, leave it alone. A stain is not the same as dirt. If there is no raised food, sticky residue, or bad smell, the stone is clean enough to use.
How to Remove Grease Stains from a Pizza Stone
Grease stains are common, especially if you love pepperoni, sausage, extra cheese, or any pizza that proudly says, “I am not here to be a salad.” Oil can soak into the porous surface and leave dark circles or blotches.
Start with dry cleaning: scrape and brush the stone. Then use baking soda paste on the greasy areas. Baking soda is mildly abrasive and helps absorb some oil without adding soap or harsh chemicals. Let the paste sit, scrub gently, and wipe clean with a barely damp cloth.
Some oil marks may never disappear completely. That is normal. The stone will darken with use, and this patina does not usually affect performance. In many kitchens, a darkened pizza stone is a badge of honor. It says, “Yes, we make pizza here, and we take cheese seriously.”
Can You Wash a Pizza Stone with Soap?
For most unglazed pizza stones, no. Soap can soak into the porous surface and leave flavor or residue behind. Even if you rinse well, the stone may hold onto the soap. When heated, that residue can affect the taste of future pizzas.
If you accidentally used soap once, do not panic. Rinse the stone briefly with warm water, wipe it several times with clean damp cloths, and let it dry thoroughly for at least 24 hours. Then heat it gradually in the oven to help drive off moisture and odor. The next pizza will probably survive. Your stone may forgive you, but it will remember.
Can You Put a Pizza Stone in the Dishwasher?
No. A dishwasher uses too much water, detergent, and heat cycling for most pizza stones. The stone can absorb water and soap, and the detergent may leave residue. Dishwasher cleaning also increases the risk of cracking or weakening the stone over time.
Clean your pizza stone by hand using scraping, brushing, baking soda paste, and minimal water. It takes only a few minutes once you get used to the routine.
Are Pizza Stone Stains Bad?
Usually, no. Brown, gray, or black stains are normal signs of use. A pizza stone naturally develops a darker surface over time as flour, oil, and food particles bake onto it. As long as the stone is dry, odor-free, and free of loose food, staining is mostly cosmetic.
You should clean the stone more deeply if it feels sticky, smells rancid, has thick burnt buildup, or leaves black crumbs on food. But if it simply looks darker than it did on day one, congratulations: your pizza stone has a personality now.
How to Deep Clean a Very Dirty Pizza Stone
If your stone has been through many pizza nights and looks like it has survived a tiny cheese volcano, try this deep-cleaning method.
Deep-cleaning method
- Let the stone cool completely.
- Scrape off raised food with a plastic or wooden scraper.
- Brush away loose crumbs and ash.
- Mix baking soda with a small amount of water to form a thick paste.
- Spread the paste over stained or sticky areas.
- Let it sit for 10 to 20 minutes.
- Scrub gently with a nylon brush.
- Wipe with a lightly damp cloth.
- Dry with a towel and air-dry completely before storing.
If the stone still has permanent stains, accept them. A pizza stone does not need to look perfect to work perfectly.
How to Dry a Pizza Stone Properly
Drying is not a tiny afterthought. It is one of the most important parts of pizza stone care. Because the stone can absorb moisture, you should let it air-dry thoroughly after any damp cleaning.
Place it upright in a dish rack or flat on a clean towel with airflow around it. Let it dry for several hours, or ideally overnight. Before using it again, put the stone in a cold oven and let it heat gradually with the oven. This helps avoid sudden temperature changes and gives any hidden moisture time to evaporate.
How to Prevent Stuck-On Food and Stains
The easiest pizza stone to clean is the one you did not turn into a cheese crime scene. A few habits can make cleanup much easier.
Use enough flour or cornmeal
Dust your peel lightly with flour, semolina, or cornmeal before sliding the pizza onto the stone. This helps prevent dough from sticking. Do not use too much, though, because excess flour can burn and leave bitter black dust.
Avoid overloaded pizzas
A mountain of sauce, cheese, and toppings may sound exciting, but overloaded pizza often leaks. Keep toppings balanced so sauce and cheese stay on the dough instead of migrating onto the stone like they own the place.
Preheat the stone correctly
Place the stone in a cold oven and let it preheat gradually. Many home cooks preheat for 30 to 60 minutes depending on the recipe and stone type. A properly heated stone helps dough cook quickly and reduces sticking.
Do not use cooking spray
Aerosol cooking sprays can create sticky buildup on stoneware. They are not necessary for pizza stones and may make cleaning harder over time.
Common Pizza Stone Cleaning Mistakes
Mistake 1: Cleaning the stone while hot
This can cause burns and may crack the stone. Always let it cool completely.
Mistake 2: Soaking it in the sink
Soaking can force water deep into the stone. When reheated, that moisture may cause cracking.
Mistake 3: Using soap
Soap can be absorbed and may affect flavor. Save the dish soap for plates, pans, and that one mug everyone mysteriously avoids washing.
Mistake 4: Scrubbing with metal tools
Metal scrapers, knives, and steel wool can scratch or damage the surface. Use plastic, silicone, wood, or nylon instead.
Mistake 5: Trying to remove every stain
Stains are normal. Remove food residue and odors, but do not obsess over color. A seasoned stone is supposed to look used.
Cleaning Different Types of Pizza Stones
Ceramic pizza stones
Ceramic stones are effective but can be sensitive to thermal shock. Let them cool slowly, avoid soaking, and use minimal water.
Cordierite pizza stones
Cordierite is known for handling high heat and resisting thermal shock better than many ceramic stones. Still, it should be cleaned gently with scraping, brushing, and limited moisture.
Glazed pizza stones
Some glazed stones are less porous and may tolerate slightly more water, but you should still follow the manufacturer’s instructions. Avoid harsh cleaners unless the care guide specifically says they are safe.
Baking steels
A baking steel is not a stone. It can usually be wiped clean, dried immediately, and lightly oiled if needed to prevent rust. Do not treat steel like porous stoneware, and do not leave it wet.
Practical Experience: What Pizza Stone Cleaning Looks Like in Real Life
In real kitchens, pizza stone cleaning is rarely glamorous. Nobody finishes dinner, looks at a cheese-splattered stone, and says, “Ah yes, my evening spa ritual begins.” Most of us shut off the oven, eat too many slices, and remember the stone the next morning when the kitchen smells faintly like toasted flour and ambition.
The first lesson from real-life pizza stone care is that waiting helps. Burnt cheese that looks impossible at midnight often scrapes off more easily the next day. Once it is completely cool and dry, a plastic bench scraper can lift surprising amounts of residue. The trick is to work in short strokes and not press too hard. If something does not come off, it probably needs paste, not punishment.
The second lesson is that baking soda paste is useful, but it is not magic makeup for cookware. It can reduce greasy spots, loosen sticky residue, and help with dark patches, but it will not always erase years of pizza history. That is fine. A pizza stone with stains can still make excellent crust. In fact, many experienced home cooks stop worrying about appearance once they realize the stone performs better than it looks.
Another practical tip: clean the stone before you clean the surrounding oven area. Brushing crumbs off the stone can send tiny bits of burnt flour onto the oven rack or floor. If you wipe the oven first and brush the stone second, congratulations, you just invented extra work.
For families or frequent pizza makers, it helps to keep a dedicated scraper near the baking tools. When the scraper lives in the same drawer as the peel, parchment paper, and pizza cutter, cleaning becomes part of the routine instead of a dramatic search-and-rescue mission. A nylon brush is also worth having, especially if you make pizza weekly.
One of the biggest surprises is how little water you actually need. A lightly damp cloth can pick up powdery residue after scraping, but too much water creates drying anxiety. If you have ever cleaned a stone and wondered, “Is it dry inside?” you know the feeling. Letting it air-dry overnight solves that problem. When in doubt, give it more drying time.
Outdoor pizza oven users often learn another lesson: heat can be a cleaner. High temperatures can burn off small bits of residue and turn them to ash. After cooling, a brush usually handles the rest. However, this does not mean you should ignore large spills forever. Thick layers of burnt sauce or cheese can smoke, smell, and affect the next bake. Brush regularly and deep clean only when needed.
The best mindset is simple: remove texture, not character. Raised chunks, sticky grease, loose crumbs, and bad odors should go. Flat stains can stay. A pizza stone is not a white tablecloth. It is a working surface built for high heat, flour, sauce, and the occasional mozzarella landslide. Let it age like a cast-iron skillet’s cousin who studied abroad in Naples.
Final Thoughts
Learning how to clean a pizza stone is mostly about learning what not to do. Do not use soap. Do not soak it. Do not put it in the dishwasher. Do not scrub it with metal tools. Do not panic when it stains. Instead, let the stone cool completely, scrape off stuck-on food, brush away crumbs, spot-clean with baking soda paste, wipe lightly, and dry thoroughly.
A well-used pizza stone will never look brand new forever, and that is perfectly okay. Those dark marks are signs of crispy crusts, bubbling cheese, Friday nights, and maybe one experimental topping combination we do not need to discuss publicly. Keep the surface clean, dry, and free of food buildup, and your pizza stone can keep turning out delicious homemade pizza for years.
