A few years ago I received a beautiful cast-iron frying pan by Lodge as a gift -- I put it in my cabinet, planning at some point to season it and use it. And then, one day, on top of it, I must have put a slightly damp stainless steel colander, because it left all sort of little rust circles all over my pan. I've attached a picture of the pan.
I've been holding onto this pan since then, not knowing what to do with it. Is it still food-safe? Is there a way to get rid of the rust? To season it anew?
I would really appreciate any help, because I would love to use this pan!
