Non cyanide method for cleaning of gold surface

In my company, after gold casting, we clean our golds surface with cyanide. I'm looking for another technique for cleaning gold before making jewelry. Can you give me some address for learn more about it.Thanks

Yes, Cyanide is good cleaning agent, but it dissolves minute quantity of gold and hence the solution should be very dilute. If the solution is saturated with AuCN then it might not dissolve gold further.
