Abstract
Procedure for removing the black spots produced on the surface of an aluminum alloy, after treating it with an aqueous liquid, characterized in that it comprises heating the stained alloy with an aqueous solution containing, in solution, 0.1 to 10% of a peroxy diphosphate calculated as the equivalent of K4P2O8, and a mineral acid that is not attacked by peroxy diphosphate, in sufficient quantity to obtain a pH of 3.0 or less for a sufficient time; to remove stains from the alloy.
