hello my name isXXXXX will assist you.
You are not going to like my answer to this question. About the only chance you have is to use easyoff oven cleaner, and a light scouring pad. Aluminum foil melts and bonds itself to the porcelan bottom. Take your time and I wish you all the luck.
You're right. That doesn't promising. Thanks.
As a tech you see this about once a year, usually closer to the holidays. How do I deserve a poor rating? I did not melt the aluminum foil, nor is it my fault it will not come off.
You asked a question and I gave you a honest answer.
