ABSTRACT:
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. The coated surface is thereby cleaned without the need of manual effort or high temperatures. The radiation is generally actinic radiation, and more particularly includes ultraviolet radiation.
