A headlamp washing assembly including spray nozzles disposed above automotive headlamps. A liquid storage reservoir stores cleaning liquid to be dispensed by the nozzles and is disposed above the nozzles to provide a gravity feed of the liquid from the reservoir to the nozzles. A gas storage tank stores gas supplied to it from a source and supplies the pressurized gas to force the liquid through the nozzles. A solenoid actuated valve is in communication with the liquid storage reservoir, the gas storage tank, the source of pressurized gas and the nozzles through appropriate conduits. The valve has a first position for charging the gas storage tank from the source of gas while simultaneously charging the metering conduits leading to the nozzles with liquid from the liquid storage tank. The valve has a second position for subjecting the metering conduits to gas from the gas storage tank to force liquid through the conduits and out the nozzles.
