A little patina only increases the beauty of gold jewelry―but when the luster is gone, a quick clean is in order. You can skip the expensive cleansers and reach for a common household product to polish your gold. Watch this video.
Two bowls of warm water, dishwashing liquid, soft-bristle toothbrush, gold jewelry
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 jewelry thoroughly and buff it a little to bring back the shine.
