the bottom of my pan is now a dark silver instead of black. the inside sides of the pan is still black. I used brillo pads to clean it and now I fear I have ruin this pan as well as another that have been passed down from generations to me. Can they be repaired?
It sounds like you may have scrubbed the seasoning off your pan. It is not ruined, but will need to be re-seasoned. As you can see on the right, where it says "related", there are a number of links to questions and answers about cast iron seasoning.
