Brake cleaning fluid is nasty and toxic... if you use it in aerosol form you can inhale it.
I came up with this when doing a complete overhaul on my daughters bike, front crank
bearings, chain cleaning, and rear bearings. Had a can around from doing the brakes on my car. I was so surprised to see how easy it removed every thing with out even having to
wipe it down. Only use this method, (outside with a catch pan under your chain ), but it
is fast and easy, and does a perfect job.
