It would be nice to find a product that works well, along with a nylon brush for scrubbing the bottom of the cylinder to get it spotless.

The nylon brush I have only really scrubs the sides.

For my .44 BP guns I use a tool I made from an old electric toothbrush. Some have a round brush which can be easily removed. Trim it down to fit the cylinder with a Stanley knife, and glue it on to a bit of dowel (I used a 5.56mm case) and you can reach the bottom of the cylinder and give it a twirl to clean. Also works well on nipple recesses.
