ABSTRACT:
A food-safe composition for the pretreatment of a surface, preferably an oven or a broiler, which may be subjected to heat is liable to soiling by organic food deposits, especially baked-on food deposits. A food-safe, inorganic thickening agent which is substantially insoluble in an alkaline aqueous composition and which is present in an amount sufficient so that, during application to the surface, the composition is capable of forming a continuous coating adhered to all desired portions of the surface, is combined with (1) an alkaline, food-safe, water-soluble inorganic salt in an amount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled, (2) a food-safe silicon polymer present in an amount sufficient so that the composition is transparent after it has been applied, dried, heated, and soiled, and optionally (3) a food-safe mineral oil present in an amount sufficient, in combination with the amount of the silicone polymer, so that the composition remains transparent or translucent after it has been applied, dried, heated, and soiled. The composition forms a transparent or translucent film after drying, preferably by heating, which remains continuous over all portions of the surface, including areas which may already be soiled with food deposits. After the film accumulates additional food soils, it remains substantially transparent. The soiled film can be readily removed by contact with water or an aqueous solution.
