Abstract
A deterging solvent essentially consists of (A) a brominated hydrocarbon of the formula: C.sub.n H.sub.2n+1 Br wherein n represents a number of 3 or above and/or a brominated hydrocarbon of the formula: C.sub.m H.sub.2m-1 Br wherein m represents a number of 2 or above. A deterging solvent composition comprises the above-described solvent (A) and a stabilizer selected from the group consisting of nitroalkanes, ethers, epoxides and amines. These solvent and solvent composition have an excellent deterging effect and usable as a substitute for the flon and chlorine solvents. Furthermore, the deterging solvent composition has a high stability.
