Ultrasonic cleaning is one of the earliest industrial applications of ultrasound. Objects to be cleaned are placed into a bath with liquid excited by ultrasonic transducers. Liquid is a water or solvent.

Cleaning of objects inside ultrasonic bath results from several mechanisms. Fast movement of liquid and cavitation result in degreasing of surface, shifting and carryover of dirt particles from surface. Cavitation is the most powerful mechanism; shock waves generated by explosions of gas bubbles are able to clean the smallest cavities of objects, that is impossible by other methods.

Ultrasonic baths for food industry are made of stainless steel; they could be equipped with timer and heating. It's possible to equip them with baskets to place different types of containers: bottles, jars etc.
