Abstract
A cryogenic cleaner for and a method of performing cleaning of a surface that must be substantially free of contaminants has a resiliently mounted nozzle for spraying a cryogenic cleaning medium on the surface. The nozzle is driven in an oscillatory manner at a predetermined amplitude and frequency so the nozzle spray is delivered in a manner to provide pulsing of the spray and to provide as 'snow plow' effect on contaminants as the spray delivers the cleaning medium against the surface. The surface is transported past the nozzle, and the cleaning occurs in an enclosed controlled environment.
