Clean Pyrex Glassware: Removing Brown Spots

Pyrex dishes are versatile and can be used for cakes, casseroles, and even sticky oven-baked ribs. However, they are susceptible to an unsightly buildup of sticky brown glaze and yellow grease stains from regular use. To restore your Pyrex to its former sparkling glory, you can try a few different methods. One method is to use baking soda and dish soap. Sprinkle baking soda on the bottom of the dish, drizzle some dish soap, and add hot water. Let the mixture soak for about 15 minutes, then scrub away the stains with a sponge. Another method is to use a Magic Eraser. Soak the Pyrex dish in hot water for about 15 minutes to loosen the stains, then scrub away the food residue with a damp Magic Eraser. For lighter stains, you can also try using a dryer sheet or Bar Keeper's Friend, an abrasive powder cleaner.

Baking soda and dish soap

Pyrex dishes are prone to an unsightly buildup of sticky brown glaze and yellow grease stains from regular use. To remove these stains, a combination of baking soda and dish soap can be used.

First, coat the bottom of your Pyrex dish with baking soda and add a drizzle of dish soap. Then, add hot water and let the mixture soak for about 15 minutes. After soaking, grab a plastic or nylon sponge and scrub away the stains, adding more baking soda as you scrub to help with stubborn spots.

This method works because the gummy residue that builds up on Pyrex is an accumulation of grease and oils. Baking soda acts as a gentle abrasive cleanser, and when combined with a degreasing dish liquid, can help to loosen and remove baked-on grease and stains.

Magic Eraser

Pyrex dishes are vulnerable to an unsightly buildup of brown spots and yellow grease stains from regular use. To remove these stains, you can use a Magic Eraser, which can serve as both a cleaner and a sponge.

Before using the Magic Eraser, it is recommended to soak the Pyrex dish in hot water for about 15 minutes to loosen and soften the stains. Then, dump the water and scrub away the burnt-on food with a damp Magic Eraser.

There are several styles of Magic Erasers on the market, so be sure to read the labels to find one that is recommended for grease-caked bakeware. After cleaning, wash the dish with soap and rinse it well.

Bar Keeper's Friend

Bar Keepers Friend is an effective way to remove brown spots from glass Pyrex pans. It is an abrasive powder cleaner that can be used to tackle baked-on food stains and scuff marks.

To use Bar Keepers Friend, first wet the surface of your Pyrex pan. Then, sprinkle the powder cleanser over the surface and spread it around to ensure the surface is coated. Leave the cleanser on for around 10-20 seconds, and then scrub the dish with a damp sponge or non-scratch scrub pad. Rinse the dish and repeat the process if necessary. Finally, dry the pan with a soft cloth and polish it to restore its shine.

Bar Keepers Friend is a powerful cleaner, so it is recommended to wear gloves when using it and to not leave the product on the Pyrex for longer than five minutes. It should also not be used in conjunction with other cleaning materials or detergents as this can cause a toxic chemical reaction.

Cornstarch and vinegar

It is important to note that this method may require some scrubbing effort, but it is an effective way to remove grease stains and brown spots from your glass Pyrex pans. For more difficult stains, you can also try soaking the pan in warm, soapy water before using the cornstarch and vinegar mixture.

Additionally, you can fill your Pyrex pan with equal parts water and white vinegar, place it in the oven at 350 degrees Fahrenheit for 45 minutes, and then rinse it. This alternative method can also help remove stubborn stains.

Oven cleaner

Be sure to follow all safety precautions on the oven cleaner's packaging.
