How to clean and maintain gold jewelry

3. Wearing a gold ring and a platinum ring on the same hand can easily cause the two to rub against each other, causing the surface of the gold ring to be partially rubbed with platinum and turn white. Rub it vigorously with a coarse cloth (such as canvas) to restore the gold's shine.

4. If there is a black silver film on the surface, you can use 2 grams of salt, 7 grams of baking soda, 8 grams of bleaching powder, and 60 ml of clean water to prepare a "gold cleaning agent". Put the gold jewelry in a bowl and pour in the cleaning agent. After 2 hours, take out the gold jewelry, rinse it with clean water (preferably not hard water), bury it in sawdust to dry, and then wipe it with a soft cloth.

5. Wiping with toothpaste or wiping with boiling thick rice soup can also restore the luster.

6. Cleaning gold jewelry with mild soap and a soft brush is the simplest and most convenient way.

7. Gold jewelry that is often worn should be cleaned and checked once a month.

8. Pure gold jewelry that loses its luster due to sweat or dust in the air can be placed in neutral detergent, warm water or commercially available maintenance liquid for a few minutes, and then gently rubbed with a neutral object.

9. Pure gold jewelry will undergo chemical changes when it encounters mercury, showing white spots. It must be roasted on an alcohol lamp for a while to restore its original color.
