Over time, gold jewelry will get dull due to residue from lotions, soaps, oils, dirt, etc. If you are like me, it is important to keep your gold looking shiny and clean.
One way to clean gold jewelry is just with soap and warm water and a few drops of ammonia. With a soft toothbrush gently brush into the small crevices to remove the dirt and grime. When you are finished, rinse thoroughly with warm water.
You can also use a liquid type jeweler cleaner that is non-abrasive. These can be purchased any where precious jewelry is sold, and in some department stores as well. An ultrasonic cleaner is not recommended if your gold jewelry has any gemstones. Many gemstones are fragile and can be easily damaged
Be careful with chlorine. Remove all gold jewelry when swimming in a pool that uses chlorine. Chlorine can permanently discolor and damage you gold jewelry. Remove your jewelry when using detergents and other harsh household chemicals. They, too, can cause damage and discoloration to the metal.
