Add a few drops of mild dishwashing liquid to a bowl filled with two cups of warm water. Drop your gold pieces into the solution and let them soak for about 15 minutes.

Lift a piece of jewelry out of the solution and gently scrub it with a soft-bristle toothbrush to remove any dirt lodged in nooks and crannies.

Swish the piece around in a bowl of warm water to remove the soapy residue.

Using a soft cloth, dry your clean jewelry thoroughly and buff it a little to bring back the shine.
