Naptha is flamable (very), but I don't think it is Carcinogenic - don't
really know however.  Most comercial PCB cleaners use either a pure CFC
(Hydrocarbon with some or all of the hydrogen replaced by Clorine or Florine,
also known as ozone depletion gas :-), or one mixed with alcohols.  Naptha
I would think would have the potential for destroying some plastic components
like relays and switches.  And, if you get a spark, you are asking for one hell
of an explosion!  Radio Shack sells a CFC/Alcohol cleaner in a spray can
which works very well, non-toxic, and non-flammable.
