1. Buy a brand new stainless revolver.
2. Transport it home in your scratch-free 4WD that never goes off road.
3. NEVER shoot it. Only shoot your other guns.
4. Only ever look at the cylinder face of that one.
The Lead-Away wiping cloths (which will remove bluing) do a very good job on it, but really, what's the point on a working firearm? The black "blast ring" is imprinted at the gun's peak pressure - but it harms nothing, and the work required to get it off is WAY out of proportion to the one shot it takes to put it back on.
Clean it off when you are getting it ready to sell the gun. Otherwise, ignore.
