At least one selected from the group consisting of compounds of the formula E- or ZR 1 CH = CHR 2 , wherein R 1 and R 2 are independently a C 1 -C 6 perfluoroalkyl group or a C 1 -C 6 hydrofluoroalkyl group Contacting the surface with a composition comprising an unsaturated fluorinated hydrocarbon; And recovering the surface from the composition. Fluorinated hydrocarbons are also used as solvent compositions in the process of depositing a fluorolubricant on a surface and in removing at least some water from the surface of a wet substrate.n n n Cleaning compositions, fluorolubricants, unsaturated fluorinated hydrocarbons, magnetic media |
