A cleaning bath for alloy parts contg. aluminum, nickel, iron, titanium, and/or copper, comprises water, an anionic surfactant, a nonionic surfactant, a corrosion inhibitor suitable for forming, on each alloy part removed from the bath, a layer that limits the corrosion of these parts, and a pH agent suitable for limiting pH variations of the cleaning bath. The cleaning bath has a wt. concn. of anionic surfactant and of nonionic surfactants of less than 3%.
