I've seen chain cleaners by Finish Line, Pedros, and I think Simple Green might have one. Reading older reviews these were frustrating & frequently broke on the first few uses. But they have been redesigned & maybe pretty good - especially if they're as fast and thorough as I've heard. I don't mind taking my chain off & going thru the manual process, but I have 4 bikes in the family and several friends who never clean their chains.

Are these now pretty good? The Finish Line is in my local EMS store at $25 for the kit.
