People are so weird with their cast iron care… I scrub it with hot water, a brush, and maybe some soap depending on how dirty it is. Then I dry it off LIKE A NORMAL PAN and heat a little oil in it again to keep it from rusting. The only thing you need to do different than a normal pan is get some oil on it and heat it up after washing. It’s a ferrous metal so it’ll rust if it isn’t protected.
