Gold can be removed with light abrasives but as the most noble of metals there is only one chemical that will dissolve it. It’s name is Aqua Regia or Royal Water. However this is very serious nasty stuff and should not be handled by anybody but an experienced chemist. My wife used to work at TRW ‘s Space Div where they built spook satellites and this stuff was utilized frequently as they gold plate a lot of circuitry parts.
Be careful
