All I use is cast iron. I never use soap, just salt to clean them. I dry them on the top of the stove (with burner on) and then coat them with oil and put them away. When you first get them you can cover them with lard, olive oil, etc. and bake it in the oven. Someone may have already said this, as I didn't read everyone's answers. Mine shine like a mirror and are smooth as satin- no sticking. Some of my pans were my grandma's.
