Abstract

A cleaning nozzle directs a spray of cleaning solution against a dispense valve or other object to be cleaned. The cleaning nozzle is evacuated to draw away cleaning solution, establishing a flow of cleaning solution through the cleaning nozzle. The cleaning nozzle is mounted on an "X-Y table" to follow similarly mounted dispense valves in order to reduce down time for valve cleaning.
