Just clean them with the same stuff your using on the blued guns. It's what I do. And yes, I have a few that are shiny! Also have a few with the case hardened look. Even have some covered with Krylon spray paint(don't ask).
Everything gets a wiping down with BreakFree cleaning solvent(not the spray paint), and any excess is removed(but not left dry).
Most everyone here has a favorite cleaning solvent....these will differ some from user to user, but the outcome is normally the same. Preventing metal from rust/pitting.
