Abstract:
Disclosed herein are solvent compositions and methods of using the solvent compositions. The solvent composition includes at least trans-1,2-dichloroethylene (t-DCE) and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TFE-TFPE). The solvent composition may also include an oxygenated solvent, such as an alcohol or fluorinated ether. A method of cleaning the surface of an article includes contacting the surface with the solvent composition to dissolve, disperse, or displace a contaminant on the surface, and removing the solvent composition containing the contaminant from the surface.
