A method for enhancing the corrosion resistance of an article comprising a silver coating deposited on a solderable copper substrate is provided. The method comprises exposing the copper substrate having the immersion-plated silver coating thereon to an anti-corrosion composition comprising: a) a multi-functional molecule comprising at least one organic functional group that interacts with and protects copper surfaces and at least one organic functional group that interacts with and protects silver surfaces; b) an alcohol; and c) a surfactant.
