Abstract
Disclosed is a method for decorating metal surfaces contaminated with water insoluble contaminants. The method prevents the formation of undesired etching and pitting of treated surfaces, thereby increasing reflectivity of such surfaces, increasing the mobility of articles treated by such method and decreasing the amount of surface coating required to achieve a desired coating thickness as compared to conventional treatment and coating methods. In one embodiment of the invention, contaminating oils present on the surface of metal containers are removed using a terpene finishing agent resulting in a metal surface roughness average of less than about 10.0 Ra.
