As long as you don't have carbon buildup which can bind the cylinder - I wouldn't worry about it. The only way to keep a gun looking brand new is to not shoot it and that's not in my vocabulary...
At the shop on stainless firearms we use Flitz Metal Polish and a dental pick for those hard to reach places. The Flitz really works well on the end of the cylinder.
God, Family, Guns, in that order.
I use the lead cloth on most of my guns but only sparingly, lightly, and only on the front of the cylinder. I agree with NGIB, use them. No closet queens for me.
Forget about it,It only gets worse in time. Mine is five years old and it's black across the front wheel.
I use green scrubbie.
