Cleaning method with solvent

A cleaning process, comprising

• dipping an object to be cleaned into a cleaning solvent composition to remove dirty component wherein either aliphatic fluorohydrocarbon as expressed by the general formula
• C.sub.n F.sub.m H.sub.2n+2-m
• wherein, n and m are positive integral numbers, being 4.ltoreq.n.ltoreq.6, 2n-3.ltoreq.m<2n+2, respectively, or a mixture of the said aliphatic fluorohydrocarbon and alcohol having a carbon number of 1 to 4 is blended with at least one member selected from the group consisting of lactam being alkyl pyrrolidone or pyrrolidone derivatives having a carbon number of 5 or 6 and/or carboxylic acid amide being formamides or acetamides having a carbon number of 1 to 4, tertiary amines having a carbon number of 5 to 12, and alcohol having ether linkage and/or amino linkage within its molecules being furfuryl alcohol, tetrahydrofurfuryl alcohol, or ethylene, diethylene, triethylene, or dipropylene glycol alkyl or monophenyl or monobenzyl derivatives having a carbon number of 3 to 10 or alkyl amino alkanols having a carbon number of 4 to 7, at a blending proportion of 10 to 95% by weight;
• thereafter rinsing the object with a rinsing agent composition which comprises a mixture of said aliphatic fluorocarbon and said alcohol having a carbon number of 1 to 4,
• wherein the object, after being rinsed, is vapor cleaned with a composition comprising a mixture of said aliphatic fluorocarbon and the said alcohol having a carbon number of 1 to 4, the rinsing agent or vapor cleaning agent composition which is used for the above-mentioned rinsing and vapor cleaning processes is an azeotropic composition of (CF.sub.3).sub.2 CFCH.sub.2 CF.sub.2 H (93.3%)/methanol (6.7%)/(CF.sub.3).sub.2 CFCH.sub.2 CF.sub.2 H (95.4%)/ethanol (4.6%), (CF.sub.3).sub.2 CFCH.sub.2 CF.sub.2 H (95.8%)/isopropanol (4.2%), H(CF.sub.2 CF.sub.2).sub.2 H (96.3%)/methanol (3.7%), H(CF.sub.2 CF.sub.2).sub.2 H (98.9%)/ethanol (1.1%), (CF.sub.3).sub.2 CFCF.sub.2 CF.sub.2 H (96.7%)/methanol (3.3%), (CF.sub.3).sub.2 CFCF.sub.2 CF.sub.2 H (97.9%)/ethanol (2.1%), CF.sub.3 CF.sub.2 CH.sub.2 CF.sub.2 CF.sub.3 (95%)/methanol (5%), CF.sub.3 CFHCFHCF.sub.2 CF.sub.3 (94.5%)/ethanol (5.5%), CF.sub.3 CF.sub.2 CH.sub.2 CF.sub.2 CF.sub.3 (97%)/isopropanol (3%), CF.sub.3 CFHCFHCF.sub.2 CF.sub.3 (92.3%)/methanol (7.7%), or CF.sub.3 CFHCFHCF.sub.2 CF.sub.3 (95.9%)/isopropanol (4.1%).
