ABSTRACT:
Highly alkaline thickened aqueous liquid hypohalite compositions containing either mineral oil, water insoluble saturated fatty acid esters, water insoluble ethers, and mixtures thereof, preferably thickened with a clay, preferably thixotropic, and containing an alkali metal silicate which can be used in a process for cleaning kitchen utensils having baked-on soils comprising the steps of treating a soiled utensil surface with the thickened alkaline hypohalite composition and then covering the treated soiled utensil surface with an excess of water at a temperature of more than about 100.degree. F. The compositions containing clay, an alkali metal silicate and the mineral oil, water insoluble ester and ethers, etc. are particularly stable, provide good corrosion protection to metals, are milder to skin than the same alkaline hypohalite compositions without the mineral oil, etc. Preferred compositions containing the silicate and saturated fatty acid esters do not leave a residue of dried product which is difficult to remove.
