Yes I clean the cylinder face on all my revolvers and remove the burn rings on my stainless guns. My nickel 586 gets to keep them, except when it's time for it's annual complete tear down. I scrub the cylinder face with Hopppe's 9 and an old bore brush (except the nickel 586. I use Breakfree CLP on it), then I firish with Iosso bore cleaner on cotton swabs to get the burn rings. I'm quite fussy about my weapons. The cylinders of my NAA .22s are the easiest. I soak them in the Hoppe's jar overnight and the cylinder face is already half clean when I remove them the next day.
