I'm trying to reseason some cast iron that was in a storage unit that flooded this year. The skillet has some rust, but I think I can get it re-seasoned ok. My problem is a cast iron muffin tin - little fishies - (too cute, especially if you live on a boat). It's really rusty, in all the little indentations & details that make the fish muffins so cute. Help! All I can think of is taking to a friend and having him dunk it in his hot tank or glass bead it.
If you have a self-cleaning oven, you can run it through a cycle and burn it all off. This will take the piece down to bare metal. Wash it really well with hot water, dry thoroughly, then season it immediately.
