Ultrasonic cleaning and washing are two different methods of cleaning objects. Ultrasonic cleaning is a technology in which items are placed in a liquid and then treated with ultrasonic waves. The sound waves create tiny bubbles in the liquid that explode and lift dirt particles off the surface of the item. Ultrasonic washing is often used to clean delicate items such as eyeglasses, jewelry and electronic components. A wash is a process in which items are cleaned with soap and water. Washes are typically used to clean clothing, bedding, and other textiles. The process may also include detergent, stain remover, or fabric softener to remove dirt and odors and leave textiles soft and fresh. Overall, both ultrasonic cleaning and washing are effective methods for cleaning items, but with different applications and technologies.
