PURPOSE:To obtain a detergent which shows excellent detergency in cleaning a flux used for soldering electronic parts by mixing a specified fluorinated cyclic ether with a compound selected from specified groups of compounds. CONSTITUTION:97-50wt.% fluorinated cyclic ether of the formula is mixed with 3-50wt.% of at least one compound selected from alcohols, ketones, esters, and hydrogen chloride to give a flux cleaning agent. This flux cleaning agent shows performance comparable to that of 1,1,2-trichloro-1,2,2-trifluoroethane (F-113) detergent and also has little possibility of causing ozonosphere destruction. Therefore when the use of F-113 detergent is prohibited, it can be suitably utilized for cleaning a flux used in soldering electronic parts. |
