Add a few drops of dishwashing liquid to a bowl of warm water. Place the gold piece in the bowl, and let it soak for 10 to 15 minutes.
Gently scrub the gold with a toothbrush to get rid of any dirt or stains. Make sure to clean any nooks or holes in the piece.
Place the jewelry piece in another bowl of clean, warm water to rinse it. Remove it from the water and pat it dry with a soft cloth.
