Gold has been a part of human culture down through the ages. In fact, the oldest gold objects were made around 4000 BC, according to the American Museum of Natural History. In modern times, most gold is made into jewelry. You must be careful with gold jewelry, however, because of scratches on its precious surface. Luckily, jewelers have machines that fix scratches in gold, but minor surface scratches can be treated at home.
Soak your gold jewelry in a small bowl of warm water and a couple of drops of a mild dish detergent. Allow the gold to soak for about five minutes to loosen any dirt and oils.
Brush the gold with a soft-bristled toothbrush to remove any remaining dirt and oils. Be gentle because you don't want to create more scratches.
Rinse the gold jewelry under warm running water to remove soap residue and dry it with a clean cloth.
Polish the scratches with a polishing cloth. You can buy this at jewelry stores. Follow the manufacturer's instructions and polish the gold gently. This will remove very light surface scratches.
