Dichloromethane ? or Methylene Chloride. Seems to strip even insulation off insulated copper wire. Use it in a well ventilated area, breathing in the vapour, not a good idea at all. Try to have the least possible on the skin. Some amounts dont cause a problem, but prolonged exposure is not a good idea. Boiling point is so low, evaporates and vanishes very fast!
