1)
Rear Derailleur - Nothing scientific about this step. Simply
get out the toothbrush, dip it in your container of degreaser
and begin scrubbing away at the rear derailleur. The main area
of build up will probably be the pulleys (two small toothed
rings in the derailleur). Get your rag and dry the derailleur
and pulleys. Try to get in all the nooks and crannies. And make
sure you wipe down the pulleys. This will be hard to dry so use
some ingenuity with rag. Its doable!
2) Front Derailleur - Follow the steps as you would with the
rear. You will not have pulleys to clean, but you will have to
get into some tight corners. So do the best you can.
IMPORTANT:
Once you have finished cleaning both derailleurs, shoot some Teflon
spray on the springs and tight areas to help lubricate the
system.
