Methods for cleaning surfaces are provided. Such a method may comprise contacting a surface with a fluid comprising a compound of Formula I for a period of time; and removing the fluid from the surface, thereby providing a cleaned surface. Vapor phase degreasing systems for cleaning a surface of a component are also provided. Such a system may comprise a boil sump comprising liquid comprising a compound of Formula I; and a holder configured to hold a component in a vapor formed from the liquid.

The present invention provides a solvent composition that can inhibit corrosion of a metal, a cleaning method using the solvent composition, and a method for producing an article provided with a coating film. The solvent composition of the present invention comprises 1-chloro-2,3,3-trifluoropropene and a specified second component, and is characterized in that the proportion of the total amount of the content of the second component to the sum of the content of 1-chloro-2,3,3-trifluoropropene and the total amount of the content of the second component is from 0.0001 to 1.0 mass %.

The present disclosure provides a degreasing apparatus which may be made at least partially, or substantially, of at least one plastic material, for use with solvents having relatively low boiling points that are chemically compatible with plastic materials, such as 1233zd (1-chloro-3,3,3-trifluoro-propene, CF.sub.3CH═CHCl). Plastic degreasing apparatuses may comprise a tank comprising a side wall and a bottom wall, a partition coupled to a lower portion of the tank, dividing the tank into an immersion sump and a vaporizing sump, a heating element located within the vaporizing sump, and a condensing element positioned above the lower portion, wherein at least one of the side wall, the bottom wall, and the partition is made of a plastic material.

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.

The present invention provides a cleaner composition having excellent cleaning properties and appropriate drying properties. The present invention is a cleaner composition including: (A) a hydrofluoroolefin having a boiling point of 30° C. or more and less than 100° C.; and (B) at least one of a perfluoropolyether having a boiling point of 100° C. or more and a hydrofluoroolefin having a boiling point of 100° C. or more, where a mass ratio of the component (A) and the component (B) is 99:1 to 55:45.
