I've been on a Corning Ware kick as of late. When visiting my local thrift stores, I've picked up a few of the old pyroceram pieces that are microwave/ range/ freezer/ stove safe.
Unfortunately, since they're so old, I'm having a hard time cleaning the baked on food or stains that their previous owners have left and were also unable to clean.
I've tried scrubbing with baking soda, and using a ceramic top cleaner. For the most part, I've been able to get rid of the metal marks, brown baked on stains, and other spots. Almost all of the pieces are back to their shiny state.
But there are some stains that are so stubborn I'm not sure how to clean. Do any of you have any tips that I could try to clean it?
I'm attaching a picture of the lasagna pan I picked up for $10! (So excited!) and its underside. The underside has a very stubborn black line along the crack that I can't get out. It looks like it's baked on sugar that's been baked and baked again.
Thanks so much
