Patent number: 6054227Abstract: An appliance is rendered self-cleaning of accumulated organic contaminants on one or more surfaces of the appliance, by coating such surfaces of the appliance with a photocatalytically-activated self-cleaning coating. Upon exposing such coated surfaces to radiation of the appropriate wavelength, for a sufficient interval of time, at least a portion of the organic contaminants present on the photocatalytically-activated self-cleaning coating are removed.
