When you use alcohol, be sure it is pure isopropyl alcohol only - some cleaners
are blends of isopropyl and methyl and/or ethyl alcohol. Both methyl and ethyl
alcohol will attack some plastics, but as far as I know, isopropyl alcohol is
completely benign. I worked in electronics manufacturing for many years and we
never had any problems using pure isopropyl.
If you buy rubbing alcohol from a drugstore, read the label carefully. Most of
what you'll find is a blend of 70% isopropyl with an unspecified "denaturant".
Look a bit more and you should be able find 99%+ isopropyl at a somewhat higher
