Abstract (en)

Cleaning apparatus is provided comprising a cleaning tank (3) which accomodates a cleaning solution (5) and an object (7) to be cleaned, and fluid supply means (4,4a) for supplying a fluid comprising air which is injected as bubbles into the cleaning solution (5), the fluid striking the object (7) to be cleaned. The fluid supply means (4,4a) supplies the fluid at a high velocity and with sufficient force that the air bubbles burst upon striking the object (7), thereby producing shock waves, including ultrasonic waves, which provide thorough cleaning of the object (7). The fluid may be air or a cleaning solution. The cleaning solution is preferably xylene or methyl ehtyl ketone.
