To me a course cloth and gun oil is where you start, then go towards the very finest steel wool with a generous coating of oil, being very cautions as you go. There may be a bronze or brass pad that is even less aggressive than 00000 steel wool.
Let's see what the others say.

I agree, with emphasis on the oil. The rust you're removing is abrasive, so you want to change out whatever you're using for a pad quite often, so that the finish, which you want to keep, gets the gentlest treatment.
