A method for removing fats, oils and cooking effluent from a range exhaust system comprising the steps of applying an adherent but peelable coating composition to the clean surfaces of the range exhaust system, allowing fats, oils or cooking effluent in use of the system to deposit on the surface of said peelable coating for a period, and after said period peeling the coating from the range exhaust system whereby to remove deposited fats, oils or cooking effluent for disposal. The coating may comprising a polyvinyl acetate polymer or copolymer emulsion or dispersion or acrylic polymer or copolymer emulsion or dispersion or a polyepoxy ester emulsion or dispersion or a styrene acrylic copolymer emulsion or dispersion or a polyurethane polymer or copolymer or a polyvinylbutyral polymer or copolymer blends of any of the above and desirably contains a biocide selected to be oil soluble and which migrates into fats, oils and cooking effluent deposited in use on the surface of said peelable coating. The coating may be applied in the form of an emulsion, dispersion or solution and is preferably formulated for dispensation as an aerosol from a pressure pack container and packaged within a pressure pack container. |
