A method for cleaning a desired surface which is liable to soiling by organic food deposits by applying to the surface a food-safe composition containing a food-safe, inorganic thickening agent which is substantially insoluble in an alkaline aqueous composition and which is present in an mount sufficient so that the composition is capable of forming a continuous coating adhered to all desired portions of the surface; an alkaline, food-safe, water soluble inorganic salt in an mount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled; a food-safe silicone polymer of the formula (CH3)3SiO[SiO(CH3)2]nSi(CH3)3, wherein n represents the number of polymer units needed to give the overall silicone polymer a minimum viscosity of 350 centistokes, which is present in an mount sufficient so that the continuous coating is transparent or translucent after the composition has been applied to the surface, dried and heated; and optionally a food-safe mineral oil, wherein, when the food-safe mineral oil is included in the food-safe composition, said mineral oil and the silicone polymer are present in a combined mount sufficient so that the composition is transparent or translucent after the composition has been applied to the surface, dried and heated. The method also contemplates drying the continuous coating to form a film, allowing the film to become soiled, and removing the soiled film with water or an aqueous solution.
