For jewelry cleaning the most effective method is found to be ultra sonic technology. Pendants and rings which have dirt and deeply embedded in them, cleaning is very difficult and most topical jewelry cleaners do not work on them. An ultrasonic jewelry cleaner can take out the grime settled deep inside these fine items of jewelry.
So how does an ultra sonic jewelry cleaner work? The jewelry items are placed in a warm soap and water solution. When you switch on the device, the motor emits ultra sonic waves which cause bubbles in the tank which contains the sap and water solution. An ultra sonic jewelry cleaner emits approximately 40000 sonic waves, which on reaching the soap solution; loosen the dirt particles deposited in the crevices of rings, pendants or any other jewelry items. After the motor is switched off, one can see all the grime collected at the base of the tank. You can take out the item, wash it in running water and pat it dry. Ultrasonic cleaners do not harm the stones or jewelry items in any way unlike chemical solutions. It is a very gentle cleaning method as there is no excessive rubbing or brushing involved.
