I use the self cleaning oven for cast iron. Works great. My grandfather use to put cast iron in his wood burning stove. A fireplace will do the job too. I don't use soap on mine and they are decades old, pitch black and slick like glass. Eggs slide out of the skillet. I use boiling water to clean, wipe dry, and wipe inside with thin layer of shortening. Cooking oil doesn't work the same as shortening for seasoning.
