What Is Stoneware Cookware, Anyway?

Before diving into cleaning methods, it helps to understand what stoneware is made of and how it differs from other cookware types. Stoneware is a type of ceramic that is fired at extremely high temperatures (over 2,200°F / 1,200°C) to create a dense, non-porous material that is highly durable and heat-resistant. Unlike earthenware, which is fired at lower temperatures and remains porous, stoneware does not absorb liquids or odors easily, making it ideal for cooking a wide range of dishes.

Stoneware comes in two main varieties: glazed and unglazed. Glazed stoneware has a smooth, shiny glass coating that makes it non-stick, stain-resistant, and easy to clean. It’s the most common type of stoneware cookware, used for Dutch ovens, baking dishes, pie plates, and ramekins. Unglazed stoneware has a matte, porous finish that is not coated with glass. It requires seasoning (similar to cast iron) to build up a natural non-stick patina, and is most often used for pizza stones, baking slabs, and some traditional cookware pieces.

No matter what type of stoneware you own, the core principles of cleaning and care are similar, with a few key differences we’ll cover later in this guide.

Why Proper Cleaning Matters for Stoneware Longevity

You might be wondering why cleaning stoneware requires special attention at all, especially since it’s known for being durable. The truth is, improper cleaning is the most common cause of stoneware damage, and even small mistakes can shorten its lifespan significantly. Here’s why following the right cleaning steps is so important:

• Prevents thermal shock and cracking: Stoneware is dense, but rapid temperature changes can cause it to crack or shatter instantly. Pouring cold water on a hot dish, or putting a cold stoneware piece directly into a hot oven, creates stress in the ceramic that leads to breaks. Proper cleaning starts with letting the cookware cool completely before handling it.
• Preserves the glaze and non-stick properties: Harsh abrasive cleaners and metal utensils can scratch the glaze on glazed stoneware, creating rough spots where food and bacteria can hide, and reducing its non-stick performance over time.
• Prevents staining and discoloration: Food residue, oil, and mineral deposits from hard water can cause permanent stains if left on the stoneware for long periods. Regular cleaning removes these substances before they have a chance to set into the surface.
• Eliminates bacteria and lingering odors: Food residue left on stoneware can harbor bacteria and cause unpleasant odors that transfer to your next dish. Proper cleaning and sanitizing keep your cookware safe and fresh for every use.

With the right care, a high-quality stoneware piece can easily last 20 years or more, making it one of the most long-lasting investments you can make for your kitchen.

What You’ll Need to Clean Stoneware Cookware

You don’t need any fancy, expensive cleaning products to care for your stoneware. Most of the supplies you’ll need are already in your kitchen. Here’s a full list of what to have on hand:

For Regular Daily Cleaning

• Warm water
• Mild dish soap (avoid harsh degreasers or antibacterial soaps with bleach)
• Soft sponge or non-abrasive scrubber
• Microfiber cloth
• Drying rack
• Plastic or silicone scraper (for removing excess food)

For Stain and Discoloration Removal

• Baking soda
• White vinegar
• 3% hydrogen peroxide (the kind found in most drugstores)
• Lemon juice
• Cream of tartar
• Coarse salt (for unglazed stoneware)
• Non-abrasive scrub pad or soft-bristled brush

For Deep Cleaning and Sanitizing

• Oxygen bleach (like OxiClean, avoid chlorine bleach)
• Large basin or sink
• Soft-bristled brush

All of these supplies are inexpensive and widely available, so you won’t need to make a special trip to the store to get started.

Step-by-Step: How to Clean Stoneware Cookware After Regular Use

Cleaning your stoneware after each use is the easiest way to prevent stains, buildup, and damage. Follow these simple steps for regular, everyday cleaning:

1. Let the cookware cool completely first. This is the most important step to avoid thermal shock and cracking. Wait at least 30-60 minutes after taking the stoneware out of the oven or off the stove before cleaning it. If you’re in a hurry, you can leave it on the counter to cool while you eat.
2. Scrape off excess food debris. Use a plastic or silicone scraper to remove any large, loose pieces of food from the surface. Never use metal utensils for this step, as they can scratch the glaze.
3. Wash with warm, soapy water. Fill your sink or a basin with warm water and add 2-3 drops of mild dish soap. Submerge the stoneware and let it soak for 10-15 minutes if there’s light food residue. For lightly used pieces, you can skip the soak and wipe it down directly with a soapy sponge.
4. Scrub gently. Use a soft sponge or non-abrasive scrubber to gently clean the entire surface of the stoneware, paying extra attention to corners, edges, and crevices where food can get stuck. Avoid applying too much pressure, as this can scratch the glaze over time.
5. Rinse thoroughly. Rinse the stoneware under warm running water to remove all soap residue. Leftover soap can leave a strange aftertaste in your food the next time you use the cookware, so make sure to rinse it well.
6. Dry completely. Dry the stoneware immediately with a clean microfiber cloth, or let it air dry on a drying rack. It’s critical that the piece is 100% dry before storing it, as leftover moisture can cause staining, mold, or even cracking if it freezes in cold temperatures.
7. Buff for extra shine (glazed only). For glazed stoneware, you can buff the dry surface with a clean, dry microfiber cloth to restore its glossy finish.

Following these steps after each use will keep your stoneware in great condition and minimize the need for heavy-duty stain removal later.

How to Remove Baked-On Food and Stubborn Stains from Stoneware

Even with regular cleaning, you’ll eventually end up with baked-on food or stubborn stains that won’t come off with soap and water alone. The good news is that you can remove almost any stoneware stain with simple household ingredients, no harsh chemicals required. Follow these steps for tough, baked-on messes:

1. Let the stoneware cool completely before starting, just as you would for regular cleaning.
2. Scrape off as much loose baked-on food as possible with a plastic scraper. Don’t press too hard, as you don’t want to scratch the glaze.
3. Make a thick paste of equal parts baking soda and warm water. For extra tough stains, add 1 teaspoon of white vinegar to the paste (it will fizz, which is normal) and let it sit for 5 minutes until the fizz stops.
4. Spread the paste generously over all the stained and baked-on areas, making sure to cover every bit of stuck-on food.
5. Let the paste sit for 30 minutes to 1 hour for light stains, or up to 4 hours for very stubborn, burnt-on messes. For extra tough food, cover the paste with a damp paper towel to keep it from drying out while it works.
6. After soaking, use a non-abrasive scrub pad or soft-bristled brush to gently scrub the stained areas. The mild abrasive texture of the baking soda will lift the food without scratching the glaze.
7. Rinse the stoneware thoroughly with warm water to remove all baking soda residue. If any stains remain, repeat the process or move on to the discoloration removal method below.

Pro Tip: For baked-on food on pizza stones or large baking slabs, sprinkle a thick, even layer of baking soda over the stain, then spray with white vinegar. Let the mixture fizz and sit for 1 hour, then scrub and rinse for best results.

How to Get Rid of Discoloration and Burnt Edges on Stoneware

Discoloration (usually brown, yellow, or orange stains) and burnt edges are common issues for stoneware, especially if you frequently cook at high temperatures or leave food in the cookware for long periods. These stains are caused by burnt food, oil buildup, or mineral deposits from hard water, and they’re easy to remove with the right method:

1. Make a paste of 3 parts baking soda to 1 part 3% hydrogen peroxide. Note: For unglazed stoneware, skip the hydrogen peroxide and use only baking soda and water, as hydrogen peroxide can be absorbed into the porous surface.
2. Spread the paste evenly over all discolored areas, making sure to cover every stain.
3. Let the paste sit for 2-4 hours for light discoloration, or overnight for very heavy, dark stains. Cover the paste with a damp paper towel if needed to keep it from drying out.
4. After soaking, scrub the stained areas gently with a non-abrasive scrub pad. The baking soda will lift the stain, while the hydrogen peroxide breaks down the organic compounds causing the discoloration.
5. Rinse the stoneware thoroughly with warm water, then dry completely.

For hard water mineral stains (white, chalky deposits), you can use an alternative method: mix equal parts lemon juice and cream of tartar to make a paste, apply it to the stains, let it sit for 1 hour, then scrub and rinse. For unglazed stoneware, scrub discoloration with a paste of coarse salt and warm water, as salt is a mild abrasive that won’t damage the porous surface.

How to Clean Glazed vs. Unglazed Stoneware Cookware

As we mentioned earlier, glazed and unglazed stoneware require slightly different cleaning approaches due to their different finishes. Here’s a breakdown of how to care for each type:

Cleaning Glazed Stoneware Cookware

Glazed stoneware has a smooth, non-porous glass coating that is highly resistant to staining and scratching. You can clean it using the regular soap-and-water method outlined earlier without any issues. For stains, you can safely use baking soda paste, hydrogen peroxide, or white vinegar, as the glaze prevents these substances from being absorbed into the cookware. Most glazed stoneware is also dishwasher safe (check the manufacturer’s instructions first, as some hand-painted or decorative glazes can fade in high-heat dishwasher cycles), though hand washing is always recommended to preserve the glaze’s shine and longevity. The only thing to avoid with glazed stoneware is harsh abrasive scrubbers, which can scratch the glaze over time and lead to permanent staining.

Cleaning Unglazed Stoneware Cookware

Unglazed stoneware has a porous, matte finish that absorbs liquids and oils, so it requires more careful cleaning to preserve its natural non-stick patina. Never use soap on unglazed stoneware, as it will be absorbed into the pores and leave a soapy aftertaste in your food for months. Instead, clean unglazed stoneware after each use with hot water and a stiff-bristled brush, scrubbing off any food residue. For stuck-on food, sprinkle a thick layer of coarse salt over the surface, scrub with the brush, then rinse with hot water. Dry the piece immediately and thoroughly with a clean cloth, then place it in a warm oven (200°F / 93°C) for 15-20 minutes to evaporate any remaining moisture and prevent cracking.

To season unglazed stoneware (build up its natural non-stick layer), rub a thin layer of food-grade mineral oil or flaxseed oil over the entire surface, then bake it in the oven at 450°F (232°C) for 1 hour. Repeat this process 2-3 times to create a dark, smooth patina that improves with age.

How to Deep Clean and Sanitize Stoneware Cookware

Even with regular cleaning, stoneware can harbor bacteria, mold, or lingering odors over time, especially if it’s been stored while damp. Deep cleaning your stoneware once a month will keep it in top condition and extend its lifespan. Follow these steps for a thorough deep clean:

1. Fill a large sink or basin with warm water and 1/2 cup of oxygen bleach (like OxiClean) per gallon of water. Never use chlorine bleach, as it can discolor the glaze and weaken the ceramic over time.
2. Submerge the stoneware completely in the solution, making sure all surfaces are covered. If you’re cleaning a large piece like a Dutch oven that doesn’t fit in your sink, you can soak it in a bathtub or large plastic bin.
3. Let the stoneware soak for 2-4 hours, or overnight for very dirty or smelly cookware. To neutralize strong odors from garlic, fish, or other pungent foods, add a few slices of lemon or 1 tablespoon of baking soda to the soak solution.
4. After soaking, scrub the entire surface of the stoneware with a soft-bristled brush to remove any remaining residue.
5. Rinse the stoneware thoroughly under warm running water to remove all bleach residue.
6. Dry the piece completely with a microfiber cloth, then let it air dry for a few hours before storing to ensure no moisture remains.

If you prefer to avoid bleach, you can sanitize stoneware with a solution of equal parts white vinegar and water. Soak the cookware for 1 hour, then rinse and dry completely. This method kills bacteria and removes lingering odors without harsh chemicals.

How to Maintain Stoneware Cookware to Prevent Damage and Staining

Preventive care is the easiest way to keep your stoneware in great condition and avoid the need for heavy-duty cleaning. Follow these simple maintenance tips to extend the life of your cookware:

• Avoid thermal shock at all costs. Never put hot stoneware in the fridge, freezer, or under cold water, and don’t preheat an empty stoneware dish in the oven. If you’re putting a cold stoneware piece into a hot oven, place it in a cold oven and let it preheat with the oven to avoid rapid temperature changes.
• Use gentle utensils. Always use silicone, wood, or plastic utensils when cooking with stoneware, as metal utensils can scratch the glaze and cause chips. Never cut food directly on the surface of stoneware, as this will damage the finish.
• Store carefully. Don’t stack heavy stoneware pieces on top of each other, as this can cause chipping. If you do need to stack pieces, place a paper towel or felt pad between them to prevent scratching. Store stoneware in a cool, dry place away from direct sunlight, which can fade decorative glazes over time.
• Don’t leave food in stoneware for long periods. Acidic foods like tomato sauce, citrus, and vinegar can stain the glaze if left in contact for hours or days. Transfer leftover food to a separate container as soon as it cools.
• Re-season unglazed stoneware regularly. For unglazed pieces, re-season the surface every 3-6 months, or whenever it starts to look dull or food begins to stick. This maintains the non-stick patina and prevents cracking.
• Inspect for damage regularly. Check your stoneware for small chips, cracks, or deep scratches before each use. If you notice damage, stop using the piece for cooking, as bacteria can get trapped in cracks and the piece may shatter when heated.

Pro Tip: If you notice food sticking to your stoneware more than usual, it’s a sign that it needs a deep clean or re-seasoning (for unglazed pieces). Don’t keep cooking with it as-is, as the stuck-on food will only get worse and harder to remove over time.

What to Avoid When Cleaning Stoneware Cookware

Knowing what not to do is just as important as knowing the right cleaning steps. Avoid these common mistakes to keep your stoneware in perfect condition:

• Never use harsh abrasive cleaners. Steel wool, scouring pads with harsh grit, and powdered cleansers like Comet will scratch the glaze on glazed stoneware, leading to permanent staining and reduced non-stick performance. Stick to soft sponges and non-abrasive scrub pads.
• Don’t use chlorine bleach. Chlorine bleach can discolor the glaze and weaken the ceramic over time, making it more prone to cracking. Stick to oxygen bleach or vinegar for sanitizing.
• Avoid the dishwasher for most stoneware. Even if your stoneware is labeled dishwasher safe, the high heat and harsh detergents can dull the glaze over time, and the rapid temperature change from the hot wash cycle to the cool drying cycle can cause thermal shock and cracks. Hand washing is always better for longevity.
• Don’t use metal utensils. Metal scrapers, spoons, and tongs can scratch the glaze and cause small chips. Stick to silicone, wood, or plastic utensils for all stoneware cooking and cleaning.
• Don’t soak unglazed stoneware for long periods. Unglazed stoneware is porous, so soaking it in water for hours can cause it to absorb excess moisture, which can lead to cracking when heated. Clean unglazed pieces quickly with hot water and dry them immediately.
• Never use oven cleaner on stoneware. The harsh chemicals in oven cleaner can damage the glaze and leave toxic residues that are unsafe for food contact.
• Don’t place stoneware directly on stovetop burners. Direct high heat from a stovetop can cause stoneware to crack or shatter. Always use a trivet or stovetop grate if you need to heat stoneware on the stove.

Frequently Asked Questions About Cleaning Stoneware Cookware

We’ve answered hundreds of questions about stoneware care over the years, and these are the most common ones we hear from home cooks:

Can I put stoneware cookware in the dishwasher?

Most glazed stoneware is technically dishwasher safe, but hand washing is always recommended for longevity. The high heat and harsh detergents in dishwashers can dull the glaze over time, and rapid temperature changes can cause thermal shock and cracks. Unglazed stoneware should never be put in the dishwasher, as soap will be absorbed into the porous surface and affect the seasoning and flavor of your food.

Why is my stoneware cookware turning brown or yellow?

Discoloration is usually caused by burnt food, oil buildup, or hard water mineral deposits. You can remove most discoloration with a baking soda and hydrogen peroxide paste, as outlined in the discoloration removal section above. For unglazed stoneware, a light brown patina is normal and actually a sign of a well-seasoned piece, so you don’t need to remove it unless it’s affecting the flavor of your food.

Can I use steel wool to clean stoneware?

No, never use steel wool or harsh abrasive scrubbers on stoneware, especially glazed pieces. These tools will scratch the glaze, leading to permanent staining and reduced non-stick properties. Always use a soft sponge, non-abrasive scrub pad, or soft-bristled brush for cleaning.

How do I remove rust from stoneware cookware?

Rust on stoneware is usually from metal utensils or hardware (like the lid of a Dutch oven) left in contact with the surface. To remove rust, make a paste of baking soda and water, apply it to the rust spot, let it sit for 30 minutes, then scrub gently with a non-abrasive scrub pad. Rinse thoroughly and dry completely. For unglazed stoneware, you can use a small amount of white vinegar on a cloth to rub off the rust, then rinse and re-season the affected area.

Can I use cooking spray on stoneware cookware?

It’s best to avoid cooking spray, as it contains lecithin and other additives that can build up on the surface of stoneware, causing staining and reducing its non-stick properties. Instead, use a small amount of regular cooking oil or butter to grease your stoneware before cooking.

Can I use stoneware cookware if it has a small chip or crack?

Small chips in the glaze are usually okay for cooking, but if the chip is deep enough to expose the porous ceramic underneath, bacteria can get trapped in the crack, so it’s best to stop using that piece for food contact. Cracks in the body of the stoneware are a bigger problem, as they can expand when heated, causing the piece to shatter. If your stoneware has a large crack, stop using it immediately.

How often should I deep clean my stoneware cookware?

You should deep clean your stoneware once a month if you use it regularly, or every 2-3 months if you use it occasionally. If you notice lingering odors, stubborn stains, or food residue that won’t come off with regular cleaning, it’s time for a deep clean.
