Gold jewelry needs to be cleaned regularly, and it is easy to lose its original luster if it is not cleaned for a long time. If it's just small dust, you can directly clean it with clean water [preferably boiled water] and gently wipe it with a soft brush or cloth. If the dirt is serious, you can use toothpaste and neutral cleaning solution, and it is best to buy professional jewelry cleaning solution, which can not only remove the dirt, but also increase the brightness of jewelry. In addition, the following points should be noted when cleaning:

(1): Do not use water containing bleaching powder to avoid unpredictable chemical reactions.

(2): Toothpaste and neutral detergent are good choices, but don't use toothpaste with grinding and grinding functions, which will easily cause irreparable wear.

(3) Ultrasonic wave is also a good washing method, but don't use platinum and palladium jewelry inlaid with precious stones to avoid falling off, loosening or even breaking. If it is a ring inlaid with K gold, if it is inlaid with precious stones, the washing time should not exceed 5 minutes to prevent the precious stones from being damaged.

(4) Don't use boiled water or boiled jewelry, which is extremely dangerous. Is it easy to produce platinum and palladium jewelry with gems? Thermal expansion and cold contraction? Fragile. In addition, minerals in water are easy to precipitate on the surface.
