I have been using
1) Kroil to break down the carbon, 20 min soak
2) J-B Blue paste, to remove majority
3) J-B Red paste, every 3rd time
4) Hoppe's No.9 with nylon brush to clean all the JB out
5) Finally Lock Ease Graphite to finish the job off
I am happy with the results. No doubt that many will not agree but that is why they make so many different products.
