Method of facilitating mitigation of cosmetic imperfections associated with fingerprint impressions on anodized materials and anodized materials treated for providing same

An article of manufacture exhibiting mitigation of cosmetic imperfections thereon, comprising:

• a substrate defining a surface subject to deposition of a lipid-containing contaminant thereon that cause said cosmetic imperfections, wherein the surface of the substrate comprises at least one of metal and metal oxide;
• at least one enzyme on the surface of the substrate for enzyme-functionalizing the surface of the substrate, wherein the at least one enzyme comprises or consists of a lipase enzyme, and wherein the at least one enzyme enables the surface of the substrate to catalyze the hydrolysis of ester bonds of lipids of the lipid-containing contaminant deposited thereon;
• a liquid activation composition on the surface of the substrate in contact with the at least one enzyme and comprising at least one constituent component that causes formation of a water-soluble surfactant on the surface of the substrate in response to the at least one constituent component being enzymatically degraded by the at least one enzyme.
