Abstract
A food-safe film for the pretreatment of a surface, preferably an oven or a broiler, which is liable to soiling by organic food deposits, especially baked-on food deposits. The film comprises a food-safe, inorganic thickening agent present in an amount sufficient so that, during application to the surface, the film forms a continuous coating adhered to all desired portions of the surface; an alkaline, food-safe, water-soluble inorganic salt in an amount sufficient so that the film is readily removable with water or an aqueous solution after it has been soiled; a food-safe silicone polymer present in an amount sufficient so that the film is transparant after drying and heating; and optionally can comprise a food-safe mineral oil present in an amount sufficient, in combination with the amount of the silicone polymer, so that the film remains transparent or translucent after drying and heating. The film is transparent or translucent after drying, preferably by heating, and 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. Finally, the soiled film can be readily removed by contact with water or an aqueous solution.
