| 摘要 |
The invention provides dry cleaning liquid formulations and methods for their use based on a highly fluorinated organic solvent which contains at least one hydrogen atom per molecule, in particular, highly fluorinated hydrocarbons or highly fluorinated ethers. In a preferred embodiment the cleaning liquid contains an HFC or HFE in combination with dichloroethylene. The addition of a surfactant enhances the ability of the liquid to remove water-soluble soils.
