Abstract

Abstract Liquid flow rate and thus volume consumed is reduced in a cleaning system which includes means for supplying a gas under high flow rate, low pressure to a mixing nozzle, and means for supplying a cleaning liquid to the mixing nozzle where the liquid and gas are combined so that the pressurized gas flow carries liquid droplets to a surface to be cleaned.
