ABSTRACT:
A metal surface, particularly a tinplate surface of a can for canned food, is treated by contact with a solution containing a zirconium compound, particularly ammonium zirconium carbonate or zirconium acetate. An inorganic salt may also be present in the solution. The concentration of the zirconium compound, calculated as ZrO.sub.2, is in the range between 0.1 and 10% w/w. The surface is thereafter heated to a temperature in the range between 20.degree. and 300.degree. C. until it is dry. The surface may be cleaned prior to contact with the solution. In this way a coating is provided on the surface which improves the stain resistance of the surface.
