A composition for the pre-treatment in aqueous form of a surface, preferably of an oven, which is subjected to heat and is liable to soiling by baked-on organic food deposits. A food-safe, inorganic thickening agent, in an amount sufficient so that the composition is capable of forming a continuous coating adhered to all desired portions of the preferably cleaned surface, which coating also remains continuous as the coating dries, preferably by heating, is combined with an alkaline, 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. The composition forms a continuous film after drying. After the film becomes soiled, it can be readily removed by contact with water or an aqueous solution.
