Yes, silverware can be polished with alcohol when it is dim, and silverware can be used as a wine container to sterilize and inhibit bacteria. General cleaning, you can soak in alcohol for a few minutes and then take it out. Ordinary sweat stains will be evaporated with alcohol, then washed with water and dried.

Besides alcohol, there are other ways to clean silverware:

(1) When sweat and dirt are often accumulated due to loading, you can gently brush the bottom of the base and the fine seam where the diamond is set with an old toothbrush dipped in neutral cleaning solution or commercially available jewelry cleaning solution, otherwise the gem will lose its luster because of its overall transparency.

(2) Generally, shops provide ultrasonic cleaning, but before cleaning, you should carefully check whether the inlay claw is loose, otherwise it will become more loose due to its high-frequency vibration, and the probability of the gem falling off the inlay base will also increase.

(3) In addition to cleaning, the surface of K gold will be covered with tiny wear marks due to long-term friction, which will also reduce the brightness. On weekdays, polishing the surface of K-gold with K-gold cloth will have a polishing effect, but it is best to do polishing and fine plating once every 2~3 years, and the jewelry will restore its original beautiful brightness.
