A cleaning solvent composition comprising an aliphatic fluorohydrocarbon represented by the general formula C n F m H 2n+2-m (wherein n and m represent each a positive integer provided that 4 ≦ n ≦ 6 and 2n-3 ≦ m < 2n+2) or a mixture thereof with a C₁-C₄ alcohol and, further added thereto, a lactam and/or a carboxamide, a tertiary amine or an alcohol having an ether linkage and/or an amino linkage in its molecule. A cleaning method comprising removing dirty components by dipping in the above composition, conducting rinsing with the above mixture and thereafter, if necessary, conducting steam cleaning with the mixture. It is possible to obtain a cleaned article free from stain and dirt in a simplified drying step, because rinsing and steam cleaning can be conducted in a nonaqueous system with a cleaning solvent composition which does not destruct ozone, is nonflammable and has a potent detergency. |
