We use this process mostly for smoke or fire damaged items that require intense cleaning. The process involves the cleaning of the items in a submersible tank that heats up and sends out millions of ultrasonic waves into the solution. The process works great on electronics items, plastics, toys, fired ceramics, silk flowers, kitchen items and pretty much any hard surfaced item. The biggest advantage to ultrasonic cleaning is that it can clean every part of an object. Also it removes smoke from plastics which is just about impossible without the Ultrasonic wave machine.
