Joe, *Electronic* contact cleaner (used to) contain(s) one of the
lower-vapor-pressure Freons, often with some silicone lube.  Dunno exactly what
the solvent is now, but it's not generally harmful to plastics.  *Industrial*
contact cleaner, OTOH, also contains something like methyl chloride which gives
it more bite -- and melts plastic.  Check the labeling on the can for warnings,
or buy Radio Shack brand which is safe for plastics.

I'm scratching my head over one thing -- brushes are ordinarily made of carbon,
which is pretty much insoluble in everything.  Was it the brushes themselves
that went away, or a plastic housing?
