Abstract
A method and apparatus for mixing and dispensing two fluids from a nozzle comprises a mixing chamber for the two fluids defined by the nozzle. A first fluid of the two fluids is sprayed into the mixing chamber from a first aperture within the nozzle and a second fluid from a second aperture within the nozzle is sprayed into the mixing chamber. The second aperture is oriented in a direction within the nozzle such that the fluid dispensed therefrom is incident upon the first aperture for cleaning the first aperture.
