PROCESS FOR PRODUCING CLEAN ARTICLE

摘要

A process for producing clean articles comprising the steps of contacting an article bearing contaminants adherent thereto with an organic solvent except for fluorohydrocarbon and rinsing the article thus treated by contact with an aliphatic fluorinated hydrocarbon represented by the general formula: CnFmH2n+2-m. This process enables the use of organic solvents that have been difficult to use, can dispense with the use of purified water, serves to reduce the cost necessary in the drying step and waste water disposal facilities, and prevents environmental pollution.
