	There are two problems with using rubbing alcohol for this application:
(1) the water dilution will seriously affect the efficicy of the iso-propyl
alcohol as a solvent; (2) some brands of rubbing alcohol contain witch hazel
extract along other undesireable items which may leave impurities on the
solder joint and surrounding circuitry.
