Abstract

Process for cleaning metals by the spraying process with weakly alkaline aqueous solutions containing organic components corrosión protection and surfactants, as well as, if necessary, other constituents and inhibitors, characterized in that the cleaning is carried out at a ph between 7.5 and 11., preferably 8.5 to 10 and at temperatures of 20 to 80ºC with solutions containing: a) soluble salts, preferably alkanolamine salts of aromatic carboxylic acids and/or branched and/or straight chain aliphatic carboxylic acids with 6-12 carbon atoms, b) one or more non-ionogenic surfactants, c) one or more surfactant quaternary ammonium compounds, in a concentration of 0.1-4% by weight of active substance a, b and c, the weight ratio being between the non-ionogenic surfactants and the quaternary ammonium compounds from 20: 1 to 1: 1 and the weight ratio between the carboxylic acid and the sum of the non-ionogenic surfactants and the quaternary ammonium compounds from 20: 1 to 1:20.
