    摘要: A method of cleaning a solid surface is disclosed. The method involves spraying the solid surface with azeotrope-like compositions by using a propellant. The azeotrope-like compositions comprise from about 93.0 to about 98.0 weight percent 1,1-dichloro-1-fluoroethane, from about 7 to about 2 weight percent methanol, and from about 0.1 to about 0.01 weight percent nitromethane. Preferably, the propellant is selected from the group consisting of hydrocarbons, chlorofluorocarbons, hydrochlorofluorocarbon, hydrofluorocarbon, dimethyl ether, carbon dioxide, nitrogen, nitrous oxide, methylene oxide, air, and mixtures thereof.
