I've heard from several sources that the iron is supposed to be good for the diet. I love my carbon steel and cast iron kitchenware. All of the studies I've seen show it as a superior option to PFAS cookware and will still outlast the latest ceramic options. I have a very non-stick carbon steel pan and griddle from avocado oil seasoning.
You didn't mention that you're oiling it after drying it. It's recommended that you lightly oil the surface upon storage.

It seems obvious you purchase equipment for restaurants. /s
Quite a hot take there. You ignored carbon steel in the conversation.
A large number of restaurants use rolled carbon steel or cast iron for searing and shallow frying.
