I suggest putting hot water in it and adding a couple of denture cleaners to the water and let it sit all night. I do this also in our bathroom toilets, works like a charm. Good luck.

Have you contacted Corning to ask if they have a answer to your problem. They might even send a replacement to you.

I have a three piece set of Pyrex mixing bowls that I received as a wedding gift in 1964. One of the bowls has always had a small rust colored spot on it. The spot is just like it is embedded in the glass. I have tried several things to remove it and nothing works, and when run my finger over it I can't feel anything. Therefore I decided it is a flaw in the glass and quit worrying about it.

You should be able to buy Bon-Ami which is a non-abrasive cleanser in most grocery stores. I've used it on all my Corning Ware and it does a beautiful job of cleaning.
Here are archived discussions related to this page.
Does anyone know how to clean silverware marks off of pyrex or corning, I've tried oven cleaner and scrubbing with a plastic scrubber and that didn't work.
