Swim has been obtaining excellent results with soaking GUPs in this mixture.  It is available in a can with C02 as a propellant.  Swim's  question is this when swim boils the GUP in this solution after the tone boils away does it, precipitate its gakk into the toululene or xylene or both.  Just wondering if boiling in this concoction would make the solvents more effective. Let swim metion again that he has had very good success with the black can regarding long soaks. (24 hr.) Pulls almost everything out, but no good for those bad boys with Orange 2.
