Dont use soap. Hot water is usually sufficient once they are seasoned well. I also will use the plastic scouring things. It will stick like a ***** when you first get it but use it constantly and it will become your favorite.
I also dry mine by putting it wet on the burner and turning flame on. You have to dry them otherwise it will rust. I then spray with cooking oil. I have one that is over 60 years old that if I still cooked, I would use it every night.
Every few years we would put the whole pan, empty on a camp fire just to burn off extra stuff. 4951
