I just bought the Park's Tool along with their chain cleaner. It works AWESOME!!! I hook my bike on to my bike rack, put a large towel underneath the bike. Then I fill the Park's Tool with chain cleaner and put the tool on the lower part of the chain. Clip the two parts together and slowly back pedal the bike. My black chain is now a dark silver!!! Of course, the chain cleaner works better after you degrease the crankset and the rear cassettes and the jockey cogs which was a "big pain the the behind".
