      I've been using MEK and Q-tips. I know there are a lot of safer
      chemicals around but I use it in a well-ventilated area. It seems to
      be safe on all non-plastic electronic parts - IC's, chip caps and
      resistors, through-hole caps and resistors, etc. I am always very
      careful around trimmer caps with plastic cases; I just carefully swab
      around the soldered contacts to get as much of the flux off as I can.
