After getting some cast iron skillets off feecycle, I boiled vinegar in them and scrubbed the skillets with steel wool . . . and some, but not all, of the black coating came off. Am I supposed to try to get all the black stuff off before I can use them? Because that's years of built-up grease from who knows what, right? I thought they would stay black, but then when silver started peeking through I got confused. Any germs would bake off the pans, right?
Help!
