The lead removal cloths ( I've used Birchwood-Casey and Hoppe's, no difference) are slightly abrasive. They both say not to use on blued guns, so I would not use one on my LCRs.
The cylinders are so heavily fluted, there isn't much cylinder face left to clean. That's one thing I like about LCRs.......

..........I just clean what I can with Hoppe's.
