How to Clean and Maintain Stoneware Bakeware: Tips to Prevent Cracks and Stains

Stoneware bakeware is a kitchen workhorse—it heats evenly, retains warmth, and looks beautiful on the table. But without proper care, even the best pieces can develop cracks, stubborn stains, or lose their nonstick finish. Whether you own a Hot Dish, Double Dutch, or any other stoneware piece, a few simple habits will keep them performing for years.

In this guide, we’ll cover how to clean stoneware safely, what to avoid, and how to remove baked-on residue without damaging the surface. These stoneware maintenance tips apply to all glazed stoneware, including bakeware from Great Jones.

Why Stoneware Needs Special Care

Stoneware is durable, but it’s also porous and sensitive to sudden temperature changes. Thermal shock—caused by putting a hot dish directly into cold water or placing a cold dish into a hot oven—is the leading cause of cracks. Unlike metal pans, stoneware expands and contracts slowly, so gentle handling is key.

Additionally, food acids and high heat can cause staining or dull the glaze over time. Proper cleaning and storage prevent these issues and help your bakeware stay nonstick and attractive. Think of stoneware care as an investment in bakeware longevity.

• Always let stoneware cool completely before washing.
• Avoid placing frozen or refrigerated stoneware directly into a preheated oven.

How to Clean Stoneware: Daily and Deep Cleaning

For everyday cleaning, wash stoneware with warm water, mild dish soap, and a soft sponge or cloth. Avoid abrasive scrubbers or steel wool—they can scratch the glaze. Most stoneware is dishwasher safe, but hand washing is gentler and helps preserve the finish. If you do use a dishwasher, choose a gentle cycle and avoid high heat drying.

For stubborn baked-on food, fill the dish with warm water and a few drops of dish soap, and let it soak for 15–30 minutes. A plastic scraper or a paste of baking soda and water can lift residue without scratching. For tough stains, try a hydrogen peroxide paste: mix baking soda with hydrogen peroxide, apply to the stain, let sit for 10 minutes, then rinse. This method is effective for removing stains without harsh chemicals.

• Soak with warm soapy water before scrubbing stuck-on food.
• Use baking soda paste for gentle stain removal.

How to Prevent Cracks in Stoneware

Preventing cracks starts with temperature management. Never put a cold stoneware dish into a hot oven—always bring it to room temperature first. Similarly, don't pour cold liquid into a hot dish, and avoid placing hot bakeware on cold countertops. Use a trivet or cooling rack instead.

Also, avoid using stoneware under the broiler or on the stovetop unless the manufacturer explicitly says it's safe. Most stoneware is oven-safe up to 500°F, but the glaze may not withstand direct flame. For even heating, always place stoneware in a cold oven and preheat together—this minimizes thermal stress.

• Always preheat oven with stoneware inside for even temperature rise.
• Use a trivet or wooden board to protect countertops from hot bakeware.

Removing Stains from Stoneware

Stains from tomato sauce, turmeric, or oil are common on light-colored stoneware. To remove them, make a paste of baking soda and water, apply it to the stain, and let it sit for 15 minutes before scrubbing gently. For deeper stains, use a mixture of equal parts baking soda and hydrogen peroxide—apply the paste, cover with plastic wrap, and let it sit overnight. Rinse and wash as usual.

Another method is to fill the dish with warm water and drop in a denture cleaning tablet. Let it fizz and soak for an hour, then wash. Avoid bleach or chlorine-based cleaners—they can damage the glaze. Regular gentle cleaning also prevents stains from setting in.

• Baking soda and hydrogen peroxide paste works on tough stains.
• Denture tablets can lift stains without harsh scrubbing.

Storage and General Maintenance Tips

Stack stoneware with care—place a paper towel or felt pad between pieces to prevent scratching. If you have multiple pieces like the Hot Dish & Lid set, store the lid upside down or with a liner to protect the rim. Avoid stacking heavy items on top of bakeware, as pressure can cause hairline cracks.

Inspect your stoneware regularly for chips or cracks. A cracked piece may still be usable for dry storage, but it's unsafe for baking because bacteria can hide in cracks and heat can cause further breakage. With these stoneware cleaning tips, your bakeware will stay beautiful and functional for many meals to come.

• Store lids separately or with a protective layer.
• Discard cracked bakeware to avoid breakage in the oven.

Caring for stoneware doesn't have to be complicated. By following these simple stoneware maintenance practices—cooling before washing, avoiding thermal shock, and using gentle cleaning methods—you'll prevent cracks, remove stains, and extend the life of your favorite bakeware. Treat your Hot Dish or Double Dutch with a little attention, and it will reward you with years of even baking and beautiful presentation.
