Cleaning Pyrex glass can be a bit tricky, but don't worry, it's easier than you think. Pyrex glass is resistant to scratches and heat, but it's not immune to stains and grime.
To clean Pyrex glass, you'll need some common household items like baking soda and water. These two ingredients can help remove tough stains and leave your Pyrex glass sparkling clean.
One of the most important things to remember when cleaning Pyrex glass is to avoid using abrasive materials, like bleach or scouring pads. These can scratch the glass and leave it looking dull.
Mixing baking soda and water creates a gentle paste that can help lift away stains and grime.
Cleaning Methods
Baking soda is a trusted cleaning agent for Pyrex glass, especially when you're unsure of the best approach. Coat the bottom of your Pyrex dish with baking soda and a drizzle of dish soap, then add hot water and let it soak for about 15 minutes.
This combination is effective for tackling stubborn stains, and the abrasive texture of baking soda helps to break them down. A plastic or nylon sponge is a good choice for scrubbing away the stains, and you can add more baking powder as you scrub for extra help.
Oven cleaner can also be used on Pyrex glass, but be cautious and only spray it on the stained areas. Let it sit for about 30 seconds before wiping it away with paper towels or a soft cloth, following all safety precautions on the package.
Baking Soda and Dish Soap Method
Grab a Pyrex dish with stubborn stains and try coating the bottom with baking soda and a drizzle of dish soap. Let the mixture soak for about 15 minutes.
You can use a plastic or nylon sponge to scrub away the stains, and if needed, add more baking soda for extra abrasive power.

A mesh scrubber can also be helpful in removing tough stains, especially when combined with the abrasive texture of baking soda.
As you scrub, you may need to add more baking soda to tackle stubborn spots, but be patient and let the mixture do its job.
After soaking, the stains should be significantly lighter, and a good scrub with a sponge or mesh scrubber should leave your Pyrex dish sparkling clean.
Cleaning Vintage Supplies
For cleaning vintage Pyrex, you'll want to use gentle, non-abrasive methods to avoid damaging the delicate glass. I've found that hand washing with gentle, clear, unscented dish soap is a good place to start.
Some everyday supplies won't cut it for vintage Pyrex, so it's best to stick with the basics. Avoid using harsh chemicals or abrasive cleaners that can scratch or etch the glass.
If you do need to tackle tougher stains, you can try using a product like Barkeeper's Friend powder, but be sure to use it with caution. This powder has been recommended by some experts as a gentle yet effective cleaner.

You'll also want to dry your vintage Pyrex pieces with a soft cloth to prevent water spots and other damage. This simple step can make a big difference in keeping your vintage Pyrex looking its best.
Here are some supplies you can use to clean vintage Pyrex:
- Dish detergent (Ajax Grapefruit or any other brand)
- A scrubby pad (Ceramabryte or cooktop cleaning pads)
- Barkeeper’s Friend powder
- Razor blade scraper and/or pin and/or toothpick
- Paste wax (Minwax)
Removing Tough Stains
Barkeeper's Friend (BKF) is a safe cleaning product for vintage Pyrex, but it may not be enough on its own. It's best used with a scrubby pad to remove smaller specs of grime.
The BKF method can be effective, but it's not a guarantee. In one instance, it removed quite a lot of baked on grime, but some spots remained untouched.
Toothpicks can also be used to remove grime from small areas, but they may not be as effective as BKF. It's worth trying them out before moving on to more aggressive methods.
A razor blade scraper can be a game-changer for removing tough stains, especially globs of gunk stuck to handles. With care, you can use the sharp edge to gently lift off the gunk.
When dealing with small bits of stuck-on gunk, a razor blade can be used to scrape them off by holding it at a narrow angle and gently scraping underneath.

Cornstarch and Vinegar

Cornstarch and vinegar make a powerful stain-fighting duo. Combine 1 teaspoon of cornstarch, 1 teaspoon of vinegar, and water in your Pyrex pan to create a paste that will help remove tough stains.
This mixture works well for grease stains, and it's easy to apply. Simply use a mesh scrubber to scrub the stain, and some elbow grease to work it in.
Cornstarch helps to absorb the stain, while vinegar helps to break it down. This combination is especially effective when used together.

Remove Stubborn Baked On Grime
Removing stubborn baked on grime from vintage Pyrex can be a challenge, but don't worry, I've got some tips to help you tackle the job.
First, try soaking your Pyrex in hot, soapy water. This method can be effective for removing normal everyday stuck on food, but for tougher grime, you may need to soak multiple times.
The Magic Eraser from Mr. Clean is a safe and effective tool for removing grease stains from Pyrex. Wet it with water, apply some pressure, and scrub off the grease.
Barkeeper's Friend (BKF) is a popular cleaning product for vintage Pyrex, but it may not be enough to remove stubborn grime. You may need to use a scrubby pad to get the job done.
One thing that didn't work for me was soaking Pyrex in hot water with dish soap and Borax. It had no effect on the hard-to-remove stuff baked onto my piece.
If you have stubborn baked on grime, you can try using a razor blade scraper to remove it. Hold the blade at a narrow angle and gently scrape it under the gunk. This method worked like a charm for me!
To remove smaller bits of stuck on gunk, lightly scrape them off with the razor blade. I found this method to be much more effective than scrubbing with BKF.
For tougher stains, try sprinkling a layer of baking soda onto your Pyrex pan, adding a squirt of dish soap, and letting it soak for 10 minutes. Then, use an aggressive scrubber to remove the stains.

Pyrex glass is resistant to scratches, but abrasive cleaners can still damage the surface.
For tougher stains, a gentle scrubber like a non-abrasive sponge or soft cloth can be used with a small amount of baking soda and water to create a paste.
Method 3: Dryer Sheets
You can use an unused dryer sheet to soften food buildup on your Pyrex baking dish. Fill the dish with hot water and drop in a dryer sheet.
Let the mixture soak for about 15 minutes. Then, dump out the water and dryer sheet. The stains should now be easy to scrub away with a sponge.
After scrubbing, wash the dish again with dish soap and water to remove any residue from the dryer sheet.
Method 4: Bar Keeper's Friend
Bar Keeper's Friend is a game-changer for tough cleaning jobs. It's an abrasive powder cleaner that works wonders on baked-on food stains.
To use it, wet your Pyrex dish and sprinkle on Bar Keeper's Friend. The water and cleaner will create a paste that coats the entire dish. Let it soak for about 20 minutes.
After soaking, add a little more water and scrub again. This is a crucial step, as it helps break down tough stains. You can also use a scrubby pad to help loosen the stains.

Using Oven Cleaner on Bakeware
Using oven cleaner on bakeware can be a bit tricky, but it's doable. Spray it only on the stained areas, let it sit for about 30 seconds, then wipe away with paper towels or a soft cloth.
