I shoot my Pietta New Army revolvers every week and I have 12 extra cylinders for them. So, cleaning the cylinders can be a chore. Or you can do this:
Take the cylinders out.
Dunk the front end of the pistol(not the trigger guard) in a bucket of 10/1 water/Ballistol (COLD, hot water is for washing your undies) use old tooth brush to scrub all exposed metal.
Take it out and dry.
Run 3 wet patches and 3 dry patches through the bore with the same solution as above. Oil with Ballistol
Dunk the cylinders into bucket of 10/1 water/Ballistol. Use Brownell Speed Mop (which has six mops attached) to pump solution through all the chambers at one time.
Use tooth brush to clean cones (nipples) and surrounding area. Use compressed air (in the field I use cans of compressed air) and rags to dry.
Oil with Ballistol.
Done.
Total time cleaning two revolvers and 12 cylinders is 40 minutes. Note I don’t remove the cones from the cylinders. I have anti-seize lube on the threading and as long as I have been shooting and cleaning like this I have never had a cone get rusted or stuck. I don’t remove the grips either. I also have being using the same bucket of 10/1 water/Ballistol for 6 months and I top it off every few weeks. You don’t have to go completely OCD about these things, clean is clean.
