摘要

It is an object of the present invention to provide a method for removing industrial dirt adhering to an article, which is excellent in removal power of solder paste, flux residue, various oils and the like, has no flash point and is recyclable (distillation regeneration) Glycol based industrial detergent. The present invention relates to a compound represented by the general formula (1): R¹-O-[-CH₂-CH (X)-O]_N-R²(In the formula (1), R¹And R²Each represent an alkyl group having 1 to 3 carbon atoms, n represents 2 or 3, and X represents hydrogen or a methyl group. ), A glycol type solvent (A) having a boiling point of 160 to 230 C. under atmospheric pressure, water (B), and, if necessary, a tertiary amine having a boiling point of 160 to 230 C. under atmospheric pressure (C), wherein the ratio of the component (A), the component (B) and the component (C) are in the order of 5 to 35 wt%, 65 to 95 wt% and 0 to 30 wt% And an azeotropic point having an azeotropic point of 90 to 100 C. under atmospheric pressure, which is recyclable.
