Abstract

Azeotropic cleaning solvent compositions have about 96 to about 98 weight percent 1,1,1,3,3,3-hexafluoro-2-methoxypropane ("HFMOP") and about 2 to about 4 weight percent acetone, e.g., about 97 weight percent HFMOP and about 3 weight percent acetone. Another composition of the present invention has a weight ratio of HFMOP to acetone of about 24 to about 99, e.g., about 24 to 49. Conventional additives, such as surfactants, lubricants, and co-solvents, may be present in an amount not exceeding about 10 weight percent of the composition. The method of the present invention includes contacting an article of manufacture with the solvent composition to clean the article of manufacture, and then removing the solvent composition from the article of manufacture.
