  • Use of noncorrosive chemical composition for the removal of soils originating from an animal or vegetable source from a stainless steel surface
    Patent number: 5342450
    Abstract: A method of removing from a stainless steel surface a difficultly removable soil originating from an animal or vegetable source comprising the step of contacting the soil adhered to the surface with an amount of a noncorrosive chemical composition effective to ultimately essentially chemically remove the soil from at least 51% of the surface. The difficultly removable soils that can be removed by the method of the invention are otherwise ultimately essentially chemically removable from at least 51% of the surface, at the temperature at which the above contacting step is conducted, only by contact with at least one corrosive chemical composition. The method is both safe for the user and highly effective to remove the above-described soils.
