PROBLEM TO BE SOLVED: To obtain a liquid cleaner having non-flammability (noncombustibility or flame retardance) and excellent cleaning characteristics (dissolving power, aggressive nature). SOLUTION: The ternary liquid cleaner comprises a first solvent being a hydrofluorocarbon, a second solvent being a dichloroethylene, a third solvent being a hydrochlorofluorocarbon having low flammability, wherein the first solvent is present in a concentration of 10 percent to 80 percent by weight of the cleaner, the second solvent is present in a concentration of 10 percent to 60 percent by weight of the cleaner and the third solvent is present in a concentration of 10 percent to 40 percent by weight of the cleaner. The third solvent makes the whole cleaner non-flammable. The cleaner is usable as a liquid by itself. The cleaner is formulated as an aerosol by including a propellant. The cleaner has low ozone depletion potential. COPYRIGHT: (C)2004,JPO
