Abstract
Abstract CLEANING OF METAL SURFACES AND ESPECIALLY THE SURFACES OR NONFERROUS METALS AND THEIR ALLOYS, AS EXEMPLIFIED BY THE SURFACES OF ZINC BASE DIE CASTINGS, TO REMOVE DIFFICULTY REMOVABLE FOREIGN DEPOSITS THEREFROM SUCH AS, FOR EXAMPLE, BUFFING COMPOUND RESIDUES AND OTHER SOILS, E.G. GREASE AND OIL, WITHOUT ANY SUBSTANTIAL CORROSION AND DISCOLORATION OF THE METAL SURFACE. THE READY-TO-USE LIQUID CLEANING COMPOSITION COMPRISES ONE OR MORE SOAPS FROM THE GROUP OF THE AMINE AND ALKANOLAMINE SALTS OF FATTY AND ROSIN ACIDS, AN EFFECTIVE AMOUNT, SUFFICIENT TO INHIBIT CORROSION OF THE METAL SURFACE BY THE CLEANING COMPOSITION, OF ELEMENTAL SULFUR, ONE OR MORE SOLUBILIZERS FOR THE SULFUR, AND AN AQUEOUS LIQUID, USUALLY WATER.
