How to Clean CorningWare: A Comprehensive Guide to Restoring Your Cookware
CorningWare, cherished for its durability and versatility, can sometimes accumulate stubborn stains and baked-on residue. Cleaning it effectively involves a combination of gentle techniques and, when necessary, more aggressive methods to restore its original luster, avoiding harsh chemicals and abrasive tools that can damage the surface. This guide outlines best practices for keeping your CorningWare spotless and ready for generations to come.
Understanding CorningWare’s Legacy and Unique Properties
CorningWare, a beloved kitchen staple, boasts a rich history and unique material composition that informs its cleaning requirements. First introduced in the 1950s, it’s known for its heat resistance, durability, and ability to transition seamlessly from stovetop to oven to table. Understanding its construction helps us appreciate the best ways to maintain its beauty and functionality.
CorningWare is typically made of Pyroceram, a glass-ceramic material prized for its thermal shock resistance. This unique property allows it to withstand rapid temperature changes without shattering, a major advantage over traditional glassware.
Benefits of Proper CorningWare Cleaning
Maintaining the cleanliness of your CorningWare goes beyond aesthetics. Proper cleaning enhances its performance, prolongs its lifespan, and ensures food safety.
- Prolonged Lifespan: Regular cleaning prevents the build-up of stubborn stains and baked-on residue, which can eventually weaken the material.
- Enhanced Performance: Clean CorningWare distributes heat more evenly, leading to better cooking results.
- Improved Food Safety: Removing food particles and residue prevents the growth of bacteria and ensures a hygienic cooking surface.
- Maintained Appearance: Regular cleaning preserves the pristine appearance of your CorningWare, keeping it looking as good as new.
Gentle Cleaning Methods for Everyday Use
For everyday cleaning and lightly soiled CorningWare, gentle methods are usually sufficient. These methods avoid harsh chemicals and abrasive materials that could potentially damage the surface.
- Soaking: Fill the CorningWare dish with warm, soapy water and let it soak for 15-30 minutes. This loosens food particles and makes scrubbing easier.
- Washing: Use a soft sponge or dishcloth to wash the dish with warm, soapy water. Avoid using abrasive scrubbers, as they can scratch the surface.
- Rinsing: Rinse the dish thoroughly with clean, warm water to remove all traces of soap.
- Drying: Dry the dish with a clean, soft towel or allow it to air dry.
Tackling Stubborn Stains and Baked-On Residue
For stubborn stains and baked-on residue, more aggressive cleaning methods may be necessary. However, it’s crucial to choose methods that are effective without damaging the CorningWare.
Here are a few options:
- Baking Soda Paste: Mix baking soda with a small amount of water to create a paste. Apply the paste to the stained areas and let it sit for 15-30 minutes. Scrub gently with a soft sponge or cloth, then rinse thoroughly.
- Boiling Water and Dish Soap: Fill the CorningWare dish with water and add a squirt of dish soap. Bring the water to a boil on the stovetop and let it simmer for 10-15 minutes. This will help loosen stubborn residue. Let the water cool slightly, then scrub the dish with a soft sponge or cloth and rinse thoroughly.
- Oven Cleaner (Use with Caution): As a last resort, oven cleaner can be used to remove extremely stubborn stains. Always use oven cleaner in a well-ventilated area and follow the manufacturer’s instructions carefully. Apply the oven cleaner to the stained areas, let it sit for the recommended time, and then scrub the dish with a soft sponge or cloth. Rinse thoroughly with warm water to remove all traces of the cleaner. Wear gloves to protect your skin.
Cleaning CorningWare Glass Lids
CorningWare often comes with glass lids that also require cleaning. These lids can usually be cleaned using the same gentle methods as the dishes themselves.
- Dishwasher Safe: Most CorningWare glass lids are dishwasher safe. Place them on the top rack to avoid direct heat from the bottom heating element.
- Handwashing: Wash the lids with warm, soapy water and a soft sponge or cloth. Rinse thoroughly and dry.
- Stubborn Stains: For stubborn stains, soak the lids in a mixture of warm water and vinegar or use a baking soda paste.
Common Cleaning Mistakes to Avoid
Avoiding common cleaning mistakes is crucial for preserving the integrity of your CorningWare.
- Abrasive Cleaners: Avoid using abrasive cleaners, such as steel wool or scouring pads, as they can scratch the surface.
- Sudden Temperature Changes: Avoid exposing hot CorningWare to cold water, as this can cause it to crack or shatter.
- Harsh Chemicals: Avoid using harsh chemicals, such as bleach or ammonia, as they can damage the material and discolor the finish.
- Dishwasher Overcrowding: Avoid overcrowding the dishwasher, as this can prevent the dishes from being cleaned properly.

Frequently Asked Questions (FAQs)
1. Can I put CorningWare in the dishwasher?
Yes, most CorningWare is dishwasher safe, however, it is generally recommended to place it on the top rack to avoid potential damage from the heating element. Some older patterns may be more susceptible to fading over time with frequent dishwasher use, so handwashing is always the gentlest option.
2. How do I remove burnt-on food from CorningWare?
The best method for removing burnt-on food is to soak the dish in warm, soapy water for an extended period (several hours or overnight). Then, gently scrub with a non-abrasive sponge or use a baking soda paste. If the residue is particularly stubborn, simmering water with dish soap on the stovetop can also help.
3. Will baking soda scratch my CorningWare?
Baking soda is generally safe for cleaning CorningWare, as it is a mild abrasive. However, it’s important to use it as a paste rather than a dry powder, and to scrub gently. Excessive scrubbing with baking soda can potentially dull the surface over time.
4. Is it safe to use steel wool on CorningWare?
Never use steel wool on CorningWare. It is highly abrasive and will scratch the surface, leaving it dull and susceptible to further staining. Stick to non-abrasive sponges and cloths.
5. Can I use bleach to clean my CorningWare?
While bleach can be effective for removing stains, it’s not recommended for cleaning CorningWare. Bleach can damage the material and discolor the finish. It’s always best to use gentler alternatives like baking soda or vinegar.
6. How do I remove brown stains from the bottom of my CorningWare?
Brown stains on the bottom of CorningWare are often caused by mineral deposits from hard water. A solution of equal parts water and white vinegar can be effective for removing these stains. Soak the dish in the solution for a few hours, then scrub gently.
7. Can I use CorningWare on a glass cooktop?
Yes, CorningWare is generally safe to use on a glass cooktop. However, it’s essential to avoid dragging or sliding the dish across the surface, as this can scratch the glass. Lift the dish carefully when moving it.
8. What is the best way to store CorningWare?
To prevent scratching, stack CorningWare carefully with soft cloths or paper towels between each dish. Store lids separately to avoid them scratching the dishes.
9. My CorningWare has a pattern. Will cleaning affect the pattern?
Repeated washing in the dishwasher, especially with harsh detergents, can cause patterns to fade over time. Handwashing is the gentlest option for preserving the pattern. Avoid abrasive cleaners, as they can also damage the pattern.
10. Can I use a pressure cooker on CorningWare?
It’s not recommended to use CorningWare in a pressure cooker. CorningWare is designed for stovetop and oven use, but the intense pressure and heat inside a pressure cooker could potentially damage the material.
11. How do I remove burnt milk stains from CorningWare?
Burnt milk stains can be particularly stubborn. Soaking in cold water before washing can help to loosen the residue. Then, follow up with a baking soda paste or simmer water with dish soap on the stovetop.
12. What if I accidentally scratched my CorningWare?
Unfortunately, scratches on CorningWare are often permanent. While you can’t completely remove them, you can minimize their appearance by polishing the surface with a gentle metal polish designed for glass-ceramic materials. Follow the manufacturer’s instructions carefully and test on a small, inconspicuous area first.
