ABSTRACT:
A solution for cleaning metal surfaces particularly non ferrous alloys such as copper, brass and high strength aluminum alloys. The solution is prepared by mixing Ca(OH).sub.2 and KOH with equivalent sulfuric acid in water then passing the solution through a 10 micron filter. The resulting concentrate can be used full strength or diluted depending on the degree of surface oxidation of the metal to be treated.
