I don't know Comfort-Numb, I never grease over the balls, haven't since sometime in the 90's when I started using lubed wads and never have a problem with my cylinder spinning on my C&B arbor. Back in the early days I used a lot of forgotten concoctions for arbor lubrication. Later I used some red grease that came in a small plunger that was a synthetic of some type. Switched over to white lithium grease around 30 some years ago that I could obtain locally and was cheaper. After a day of shooting the cylinder never binds, taking the barrel/cylinder off, the grease is still the same color as I applied. Only exception is the first 1/8" by the chamber mouths or so that has become a brownish color from residue. I add a very small dad on the cylinder ratchets also for lube, never a problem with any buildup. General consensus by most is to avoid petroleum based grease as it and black powder residue don't mix well.
Ref grease over the balls, I don't miss the days of greasy hands, greasy revolvers, or the extra step of greasing the balls. If a shooter has properly lubed his firearm, he doesn't need all of that liquid grease that previously was a semi-solid spread over the balls but was melted by the firing, heat and blow of the first couple of shots for lubrication and proper functioning of his revolver. There's no need for all that grease spread all over the front half of the revolver. A rag back in the early days of my percussion shooting necessitated one hanging from my belt to constantly wipe all the grease that got on my hands and all over everything. Forget to bring one and ya made sure the next time you went out it was there. Still do carry a rag, but it doesn't get the use it once did.
Clean up is clean up, I use hot water (if possible, but not scalding), Ballistol, and rags and brushes. Not any harder to clean from back in the day I greased the balls. The only pain is the chamber deep in the nipple area and the exterior nipple recesses of the cylinder. I take the nipples off, only way to really get them and the recesses clean. It's a pain doing so, but do it as its the only way to really get things clean. Out in the field I never do strip, if the bore does get any buildup, I carry a small wooden dowel I cut a slot in one end for a cleaning patch and give it a few swipes with a water/Ballistol mix.
