After reading countless articles on how ultrasonics work, the various aspects of cavitation, and which frequency is better I found that most authors concentrated heavily on the theoretical parameters. The articles had little or no information on the practical side of application. To most manufacturing engineers like myself this does not help them solve their primary problem. How does it get may parts clean? Is ultrasonics right for my application? Can ultrasonic cleaning help me? How does it compare with other types of cleaning? For these reasons I review theory only briefly.
