Degrease, spin a bore swab with Flitz using the drill to polish, degrease again and lube lightly.
I like the bore swab idea.. thanks
For me, I just use a paper towel, fold it over a couple times so that it'll fit up the die, squirt some Hoppes on it, give it a few turns, wipe the outside and pack it away. No special routine for me. Maybe after 1000 odd sizings?
