I tried expensive bronze brushes and eventually they all shed bristles. After 30+ years of doing it I do say I found the best way: strips of scotchbrite pad pushed into a nylon bore brush. It not only rips off the hardened carbon, it polishes inside the tube to make it easier to clean in the future. The scotchbrite is easily changed and the brushes last a long time.
