ABSTRACT:
A novel method is provided for treating metallic or ceramic surfaces (hot plates, metallic molds and the like) at a high temperature of 200.degree. C. or above, wherein organic treating agents (finishes, release agents and the like) will not form a tar or sludge. According to this method, the continuous operation can be conducted due to neither staining on the metallic surfaces nor stop of the machine for a heater cleaning. Examples of the organic treating agents to be used include a polyalkylene glycol thermally decomposable at 150.degree. C. or above in air and a fluorine-containing compound, preferably the nonionic type, having a fluoroalkyl group in the molecule.
