Earlier this month, I was desperate and had no ice scraper. So, I had this older flat metal pizza pan with wooden handle to use one morning. And it left behind some metallic colored marks into the glass. But, it still feels smooth. No scratch feeling to it. Just a discoloration into the glass. I have tried different methods, but to no avail. What do you suggest? Thank you.
