Flammable ? 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. -- Pete Wilcox ...gatech!nanovx!techwood!paldn!pwilcox
