Gold jewelry of any karat can be cleaned lightly using a soft cloth. For a more thorough cleaning, soak your gold jewelry in a glass of warm water with a drop or two of non-detergent soap (Ivory, Dr. Bronner's, etc) to help remove any oils and loosen buildup. Remove after a few minutes and pat dry with a soft cloth. To clean further, use a very soft, worn toothbrush to carefully remove any dirt particles or debris from more intricate components and settings.
