Clean cast iron pans

Hello friends, I read your tips with a smile. That with the old greasy film is a perfect thing. That's the one thing. The other thing is the cleaning. As a rule, I rub my pans with salt and oils, then grease (brush them) again with some frying fat.
In very hard cases, I leave them at full heat on the gas stove for a very long time, min. 20 minutes, stand. (The dirt burns easily) Then I brush it out with a regular wire brush (from the hardware store). Finally, after some time of cooling, I re-grease them (with the help of the Bach brush) again.

The pan is made of cast iron, she puts it away easily.
