CONSTITUTION:A flux cleaning agent comprising a rosin is mixed with 0.01-5wt.% strongly basic substance containing an inorganic alkali salt, a quaternary ammonium hydroxide, and a diaza-bicyclo compound (e.g. caustic soda) and 0.1-50wt.% water-soluble amine containing an aliphatic alkylamine or alkanolamine (e.g. monoethanolamine).
