 I second that. WD-40 and 5.56 and the likes may be good for cars and
 motorbikes, but they should be kept well away from computers, or for
 that matter, cameras.
  The later ones are
 riveted, so you can just rmeove the springs, soak the assmebly in
 solvent, then work the parts back and forth and wipe off the old
 grease
 as it appears. I find propan-2-ol (isporpanol) woeks well  for this. 
 Interesting, propanol is an alcohol and shouldn't be very good at
 dissolving grease, in theory. I would have thought white spirit would be
 better.
