Abstract: In a high pressure spray cleaning apparatus and method there is provided separate pressurized flow circuits to separate inlets of a spray head. A chemical flow circuit delivers a cleaning chemical fluid under pressure and a carrier flow circuit delivers a heated carrier fluid, preferably water and or soap, under a relatively high pressure. The pressurized cleaning chemical fluid and heated water are intimately mixed and distributed by a novel spray head. A power-driven air compressor is coupled to a chemical storage tank containing a cleaning chemical in the chemical flow circuit. A power-driven positive displacement pump associated with a by-pass unloader valve regulates the pressure of the water from a water tank delivered to a heating coil in which the water is heated in the carrier flow circuit. When the heated water is not being sprayed at the spray head, it is automatically returned by the operation of the by-pass unloader valve at a reduced pressure to the water tank.
