Can the factory "gunk" on a new chain be effectively cleaned off while on the bike? Usually with a new chain I strip this off with a solvent bath and hang dry before I set it up on the bike, but I bought a new built-up bike and that suckers just caked with it. I could press out a pin, take it off and do my routine, or try back pedaling the chain thru a solvent soaked rag, let it dry, then lube and go. Any advice?
