Cavitation based cleaning

Abstract

The novel cavitation based cleaning devices preferably contain one or more cavitation creating elements and a reservoir holding the cavitation creating elements with an opening for introduction of an item in proximity to the cavitation creating elements. The reservoir may be or include a water filled reservoir. Collapse of bubbles created by the cavitation creating elements preferably pulls debris from the item. In some aspects, the reservoir is configured to permit introduction of an item comprising a paint brush. The debris may include wet, semi-dry, and/or dry paint on and/or inside the paint brush. The cavitation creating elements may include cylinders that spin in opposite directions within the reservoir. Cavitation is preferably created without using transonic methods or elements. Aspects of the invention also include methods performed by and/or using the novel cavitation based cleaning devices disclosed herein.
