How to Clean and Care for Your Pizzacraft Pizza Stone

Pizzacraft stones need the same gentle treatment as any ceramic or cordierite stone—no soap, no water submersion, and a cool-down period before cleaning

Pizzacraft makes several pizza stone models, most commonly their rectangular cordierite stones designed for use on home ovens and grills. Like all pizza stones, they absorb moisture and oils from dough and toppings, which means cleaning them properly keeps them seasoned rather than stripped. The biggest mistake people make is washing a Pizzacraft stone like a baking sheet—soap breaks down the seasoning layer, and water can crack the stone if it's still warm.

The core rule is simple: let the stone cool completely, then scrape off food debris with a dry brush or plastic scraper. If you need to remove stubborn spots, a damp cloth works, but the stone must be room temperature first. Never soak it, never put it in the dishwasher, and never use oil or cooking spray on the cooking surface itself—the stone seasons naturally from the fats in your dough and toppings over time.

Key Takeaways

• Always allow your Pizzacraft stone to cool to room temperature before cleaning, as thermal shock from water or cold air can cause cracking.
• Use only a dry brush, plastic scraper, or damp cloth to remove food—never soap, never submersion, and never the dishwasher.
• Stubborn burnt spots can be scraped gently or left alone; they are part of the seasoning and do not affect pizza quality.
• Store your Pizzacraft stone in a dry place, ideally still in your oven or on a shelf where it will not absorb moisture from the air.
• A light coating of flour or cornmeal on the stone before each use prevents sticking and protects the seasoned surface.

The cooling-down step is non-negotiable

Pizzacraft stones are made from cordierite, a ceramic material engineered to handle high heat but vulnerable to rapid temperature changes. When you pull a hot stone out of a 500°F oven and expose it to cool air or water, the outer surface contracts faster than the interior, creating stress fractures that spread over time. You may not see a crack immediately—it can develop after several thermal shocks.

The safest approach is to turn off your oven, leave the stone inside, and let it cool for at least 30 to 45 minutes. If you need to remove it sooner, place it on a heat-safe surface like a wooden cutting board or trivet and let it sit undisturbed. Do not set it on a cold countertop or near a window where air conditioning can speed cooling. Once it is cool enough to touch comfortably, you can clean it.

Cleaning methods that work without damaging the stone

A dry brush is your first line of defense. Use a stiff pastry brush or a dedicated stone brush to sweep away flour, cornmeal, and loose food particles once the stone has cooled. This removes most debris and takes less than a minute. For a Pizzacraft stone that has been used regularly, this dry brush is often all you need between pizzas.

If food is stuck on or burnt spots are visible, a plastic dough scraper or bench knife works well. Angle the scraper at 45 degrees and push gently—you are not trying to sand the stone smooth, just remove the stuck layer. Avoid metal scrapers, which can gouge the surface and disrupt seasoning. If scraping does not budge the spot, leave it. Burnt residue is harmless and actually adds to the stone's seasoning over time.

For stubborn residue, dampen a cloth with plain water (no soap) and wipe the cooled stone. The moisture should be minimal—think damp, not wet. Wipe in one direction, then let the stone air-dry completely before storing it. Never soak a Pizzacraft stone, never spray it with water, and never use vinegar or baking soda solutions, which can erode the cordierite.

Why soap and oil are off-limits

Soap breaks down the seasoning layer that builds up on your Pizzacraft stone over months of use. That layer is a combination of baked-on fats and proteins from dough and toppings—it is what makes the stone non-stick and improves browning. Washing with soap strips it away, and you have to start the seasoning process from scratch.

Cooking oil or spray on the cooking surface seems helpful but actually works against you. The stone seasons best from the natural fats in your dough and pizza toppings, not from added oil. Extra oil can pool in low spots, turn rancid, and create sticky patches. If your dough is sticking, the solution is more flour or cornmeal on the surface, not oil.

Storage that prevents moisture absorption

Cordierite is porous, which is why it heats evenly and browns pizza well. That same porosity means it absorbs moisture from humid air. The best storage is inside your oven—if you have space, leave your Pizzacraft stone on the oven rack or floor. It stays dry, stays seasoned, and is ready to use next time you preheat.

If you need to store it elsewhere, keep it in a dry cabinet or on a shelf away from the kitchen sink and dishwasher. Do not wrap it in plastic, which traps moisture. A cloth cover or simply leaving it uncovered in a dry spot works fine. If you live in a very humid climate, check the stone occasionally for white mineral deposits or discoloration—these are signs of moisture buildup, and you can wipe them away with a damp cloth once the stone is cool.

Preventing sticking and maintaining the cooking surface

The best way to prevent sticking is to dust your Pizzacraft stone with flour or cornmeal before placing dough on it. Use a pizza peel (the wooden kind is gentler on the stone) and coat it generously with flour, then place your dough on the peel and add toppings. The flour transfers to the stone and creates a barrier between dough and surface.

If dough sticks despite the flour, do not panic. Let the pizza cook for a minute or two—the bottom will set and release naturally. Trying to force a stuck pizza off the stone can damage both the dough and the stone. Once the pizza is done and cooled, any stuck bits will brush off easily with your dry brush.

What to do if your Pizzacraft stone cracks or discolors

Small surface cracks do not mean the stone is ruined. Cordierite is designed to handle thermal stress, and hairline cracks on the surface often do not spread. A cracked Pizzacraft stone can still cook pizza safely—the crack does not affect heat distribution or food safety. If the crack is large enough that pieces are breaking off, the stone has reached the end of its life and should be replaced.

Discoloration—dark spots, stains, or uneven browning—is normal and expected. These are signs of seasoning and use. White or chalky deposits are mineral buildup from water or humidity and can be wiped away with a damp cloth. Rust-colored stains sometimes appear on cordierite stones and are not harmful; they are oxidation in the material itself and do not affect cooking.

Frequently Asked Questions

Can I wash my Pizzacraft stone in the dishwasher?

No. The dishwasher exposes the stone to hot water, soap, and rapid temperature changes—all of which damage cordierite. Hand-clean only with a dry brush or damp cloth after the stone has cooled completely.

What if my pizza sticks to the stone every time?

Use more flour or cornmeal on your peel before placing dough on it. Make sure your dough is not too wet—wetter doughs stick more. If the stone is very smooth and new, it may take a few uses to build up seasoning; sticking usually improves after 5 to 10 pizzas.

Is it safe to use a Pizzacraft stone if it has a crack?

Small surface cracks are safe and common. The stone will still heat evenly and cook pizza normally. If large pieces are breaking off or the crack is deep enough to go through the entire thickness, replace the stone.

How often should I deep-clean my Pizzacraft stone?

You do not need to deep-clean it. A dry brush between uses and a damp wipe every few months is enough. The less you disturb the seasoning, the better the stone performs.

Can I use my Pizzacraft stone on a gas grill?

Yes, Pizzacraft makes stones for both ovens and grills. Check your model number to confirm it is rated for grill use. The cleaning and care rules are the same regardless of heat source.
