The Best Ways to Get Those Yellow Grease Stains Off Your Glass Pyrex
There are a lot of reasons to bake with Pyrex. Glass distributes heat pretty evenly and retains it fairly well, which means your casserole will stay hot at the dinner table. Plus, glass dishes tend to look more elegant than, say, a metal baking pan. And glass is normally pretty easy to clean. There’s just one exception to that (and a major con): those stubborn, yellow grease stains.
If you know what we’re talking about all too well and your glass baking dishes need a little TLC, here are a few of the best methods for making those yellow stains disappear.
1. Dish Soap and Water
The surfactants in dish soap have grease-cutting superpowers, making plain ol’ soap and water a great way to clean your bakeware. Simply take a warm, wet sponge to the stains with a few drops of dish soap, then rinse. If your stain is more stubborn, try adding baking soda to the mix. Its mild, abrasive properties (plus a little elbow grease) should do the trick.
2. Magic Eraser, $7 for nine
Is there anything a Magic Eraser can’t do? If you’re up for a little scrubbing, just wet down the eraser and get to work. For more difficult-to-remove grease stains, soak the dish in warm, soapy water before using the Magic Eraser.
3. Cornstarch and Vinegar
Because both cornstarch and vinegar are champions at removing grease stains, combine the two to make your own glass dish cleaner. Just add a teaspoon of cornstarch to equal parts vinegar and water, wet a nylon or mesh scrubber, and tackle your Pyrex’s grease-stained area.
4. Oven Cleaner
Many Pyrex-owners swear by oven cleaner, which is made to clean the same grease that’s left inside your oven. Just spray on the stain, leave it on for 30 seconds, and wipe away with a paper towel. (If that doesn’t work, try filling your Pyrex with equal parts water and white vinegar, bake at 350 for 45 minutes, then rinse.)
Because it’s made of a fine and natural abrasive, Bon Ami cleaner won’t harm or scratch your glass like other powdered cleansers. Sprinkle the cleaner on the stained areas of your Pyrex, then scrub with a damp sponge and rinse.
Think about it: Toothpaste safely polishes your teeth, so why wouldn’t it work on your glassware? Just apply a little paste to the yellow area and (you guessed it) scrub away with a toothbrush. Afterward, you’ll want to make sure to rinse with a little soap and water — especially if the toothpaste is minty.
7. Denture Cleaner
This one’s a little more unconventional, but some Pyrex owners swear by it: For a sparkling-new glass dish, add some hot water, drop in two or three denture cleaning tablets, and let everything sit for a few hours (or overnight for peskier stains). Rumor has it, the same trick works for toilets!
8. Dryer Sheet and Water
If your baking dish has a little more buildup, the conditioning properties in a dryer sheet might work like a charm. First, add warm water to the Pyrex. Add an unused dryer sheet to the water, then let it sit for around 15 minutes. Dump the water, then wipe the greasy or caked-on areas with a wet sponge. Just make sure you clean the dish with soap and water when you’re done.
