How do I fix my new non-stick pan?

4 Days ago I bought a 12 inch zwilling ceramic non-stick pan. My wife (whom I love with all my heart and is very beautiful and well intending) tried to toast some bread on it last night. The pan got too hot, or maybe she didn't use enough butter, and the bread burnt and stuck to the middle of the pan. When she went to clean it, the burn marks on the middle of the pan were very stuck and she scrubbed the middle pan very hard with a scrub daddy. This morning I went to use it to make some eggs and that spot in the middle is very stick now. Is it possible to fix? Can I take that ceramic coating thing people use on cars and rub on it? Am I stupid for asking that? Thanks so much. submitted by /u/ihavequestions2000
