After understanding this property, we can make the silver ornaments we wear as new as ever just by paying a little attention to our daily life.
1. The best way to maintain the silver ornaments is to wear them every day, because the grease of the human body will make the silver give out a warm and natural luster (except for some people, whose sweat contains the ingredients that make the Silver Black). Keep it away when you don't wear it at ordinary times. It's better to pack it in a closed pocket to prevent the silver surface from oxidation and blackening due to contact with the air.
2. The method of daily cleaning: squeeze a little toothpaste on the silver ornament, add some water, knead it properly until it has small white bubbles, and then rinse it with water to restore the brightness.
