On a related topic, waterless handcleaner, like GoJo (the non-abrasive kind), is GREAT for getting the grease off your rear wheel. Smear it on the rim dry (NO WATER), wait a minute and scrub a little with a brush. If you really want to get an-l, wipe it with a dry rag, smear some more GoJo around the tough spots, and then rinse off with water.
Other notes:
** I'm not sure why, but this doesn't work nearly as well if the wheel was wet before using the hand cleaner,
** You can use this on your chain too. The hand cleaner is basically jellied mineral spirits with some lanolin to make your hands soft.
** Unlike a lot of other cleaners, the waterless hand cleaner will not etch or discolor bare aluminum.
