An apparatus for spray washing includes a handle member which includes an air inlet and a water inlet. Both inlets lead to separate valves that are actuated simultaneously by a lever mechanism. These lead to a venturi orifice that is in communication with a reservoir of detergent that further includes a valve to open and close the passage into the reservoir. Downstream of the spray apparatus is a water valve which can be used to shut off water flow to the apparatus. The apparatus can be used to spray only air, or a combination of air and water, or a combination of air, water and detergent.
