I am not at this level by any stretch, but I have heard that serious cast iron users have a hierarchy of pans - once a pan develops a finish that really truly doesn't stick, it his tucked away, wiped only with a paper towel, and used only for eggs and pancakes and cornbread with soft tools. Browning meat and such is down on totally separate pans that are scraped down and washed as needed.
