CAVITATION & IMPINGEMENT
Cavitation is a process used in ultrasonic cleaning to remove debris and bioburden from difficult to reach areas of surgical instruments such as box locks, serrations and lumens of complex devices.
Cavitation is a phenomenon where high-frequency sound waves is passed through a cleaning solution to create bubbles, which implode to generate shock waves, strong enough to dislodge impurities adhering to the surface of the objects and lumens submerged in the cleaning solution

Impingement refers to the spray-force action of pressurized water that is normally used in automated washers to physically remove bioburden from instrument surfaces.
