White spriit would probalby be OK too. But most greases will disolve in

cleaner for most disk drive parts, so it doesn't do any damage if it gets
where it shouldn't. It also doesn't attack many plastics.
The only place I've seen this is in the form of "Rubbing Alcohol" which
tends to be 65-70% concentration. Is that sufficient and/or safe to use
on electronic parts? Can anyone in the states recommend a good source for
larger (e.g. gallon) quantities of 99% propanol? I doubt it can be
shipped by mail or UPS, so I'm hoping to find some local source.
Others have recommended Perc. Unless I'm confusing that with something
similar-sounding, it's seriously nasty stuff. Back when flux remover
actually worked, it was perc based. The EPA has clamped down on the use
of perc, although I think it's still a component of "dry" cleaning.
Lastly, what are folks' opinions on the use of "Triflow" spray silicone
lubricant for things like the Lisa load mechanism? I've used it in the
past to service CD and cassette load mechanisms without any obvious
problems.

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.
