cleaning gold zinc parts?

[mterrens]

Can anyone suggest a cleaning regimen for gold-zinc or gold-cad plated parts? I want to clean these bits without scrubbing off the plating. So far, I am either not getting the crud off, or removing the finish.
Thanks,
Steve

If you have removed the finish take a look at Eastwood's Golden Cad
spray. They also have a finish called "carb renew" that produces a gold
tone. For cleaning try "zinc dichromate" (gold zinc) in your searches.
