The solution consists of 2˜7% KAu(CN)2 or KAg(CN)2, 0.1˜0.5% H2SO4, 0.1˜0.5% methanol and balance pure water, wherein KAu(CN)2 is used in case of Au plating and KAg(CN)2 is used in case of Ag plating. The solution removes greases and oxides attached on surface of articles being plated with the consequence that the steps of water-cleaning, degreasing and oxides-removing are omitted.
