This thread contains great, detailed cleaning information. If I may, I'd like to ad one more bit of information, on cleaning the powder burns from the face of the cylinder. The one product I use and like the best is IOSSO bore cleaner; it can be used on blue guns as well, according to the product instructions. This product comes in a small tube, like toothpaste, and I use it with a tooth brush. If you clean your guns after each shootout, it will take you about one minute to clean that ugly black stuff from the from of the cylinder. If you don't clean your guns that often, you may need to use your brass bush. This stuff, in my opinion is about 100% better that the lead-away cloth. I buy it from Brownell's of Cheaper than Dirt - about $5. bucks per tube and it last for a while.
