Abstract An alkali metal hydroxide and water solution having incorporated therein nitrogen-containing anionic surfactants combined with a polyhydric alcohol to form the active concentrate of a composition for cleansing food residue and soil from preheated surfaces of cooking ovens, grilles and the like. The particular anionic surfactants present in the concentrate have the important function of inhibiting the corrosive action of the concentrate on the human skin and mucuous tissues and consist specifically of the sodium salts of the condensation product of coconut fatty acids with a complex of polypeptides and amino acids derived from proteins (Maypon SK), of a complex of polypeptides and amino acids derived as a hydrolysate from proteins (Polypeptide No. 37) and of an amido methylated lauric acid (Sodium N-Lauroyl Sarcosinate Sarkosyl NL-97). The concentrate may include a thickening agent to render it surface adhering and additionally may be packaged in an aerosol container for expulsion therefrom by a propellant with or without a foam-forming and foamstabilizing agent.
