A little unorthodox perhaps, but I chuck the end section of a cleaning rod in a power drill, screw a bore brush into the rod, apply solvent & slowly spin the drill to rotate the brush while passing it back & forth a little in the chambers. It cleans the whole inside from rim to mouth & if you use a nice long section of rod you'll never contact the finish of the revolver. Do this every time you clean & you'll never have the problem again.
