If the jadeite bracelet is not smooth after polishing, rub it repeatedly with a bamboo stick cloth with polishing powder and a proper amount of cold water until the surface is shiny. Finally, the leather wheel soaked with brightener is polished repeatedly.
5. Put the jade into the magnetic cleaner: put the jade into the magnetic cleaner. Jade cleaning liquid needs to be put into a magnetic cleaning machine, then washed with tap water, and finally dried by a hair dryer before shipment.
