Abstract
The invention discloses an apparatus and method for mixing liquid carbon dioxide with an additive or surfactant and then forcibly dispersing the mixture into a cleaning chamber full of liquid carbon dioxide. Valving controls the process of admitting a liquid additive into a two liter reservoir and then admitting liquid carbon dioxide into the two liter reservoir under pressure thus filling the reservoir. The mixture is then admitted to the cleaning chamber under pressure. A nozzle, a plurality of nozzles, or a pipe having apertures therein is used to disperse the mixture inside the cleaning chamber.
