Abstract
Liquid compsn. effectively removing oxides and other impurities from metal surfaces, esp. before other impurities from metal surfaces, esp. before soldering in the electronic industry, comprises (a) 0.01-100% of a cpd. contg. active hydrogen, selected from aliphatic, aromatic or heterocyclic amines contg. OH groups in the vicinity of N atoms, (b) 0-75% of colophony or its derivs. (c) 0-75% of an organic solvent, and (d) 0-20% of a thixotropic agent. There is no need to remove the cleaning composn. from the metal surface before soldering.
