When I was a kid we cooked a bunch with cast iron. I remember my folks saying never wash with soap. They also would heat the oven up and rub olive oil or lard on the cast iron, then bake it in the oven to season the iron.
Well, there is a much easier way.
Secure a chunk of pure beeswax. Anything as long as it is pure and no paraffin. If you have a rusted up piece of cookware, take a wire brush to it and clean it off. You can also plop it is a campfire and burn the rust off. Just make sure you let it cool slowly so it does not crack.
Place your clean cast iron on a stove top burner. Turn the heat to low and start warming up the iron. As the iron heats up, the pores in the metal open up. Once it is warm enough to melt beeswax on contact, rub the iron inside and out with the beeswax. You may wish to use a pair of leather gloves to minimize burning your self. You can also use a folded paper towel to rub the wax around. Let the cast iron cool.
You now have a super seasoned piece of cast iron. The seasoning will not go rancid as others do. It will not build up as is common. While I may wash it using soap, if I do, reseasoning is so easy.
Blacksmiths often use beeswax to finish iron. I can take a piece of iron finished in this way and leave it outside. It will often have no rust even after a year. Beeswax is a fat. There have been times when we are at reenactments and have needed fat to fry. We just cut off a piece of beeswax candle and have at it. You don’t have to worry about spilling oils.
When cleaning cast iron, I usually use hot to boiling water and no soap. Always dry off your cast iron. I do this by putting it on the heat for a bit, take it off the heat, and rub dry with a towel. Be careful not to burn yourself. It is good to use an old towel as some black may transfer from the iron to the towel. Once dry, I will heat it back up and rub the inside with beeswax. Remember, it does not build up. I keep a tightly folded paper towel that has had much use with beeswax to do this.
