A fluid discharge apparatus adapted for to commingling two pressurized fluids, such as a pressurized liquid and a pressurized gas, and for discharging the commingle fluids in a high pressure spiral stream that is particularly useful in washing dirt, debris, barnacles, and other substances from surfaces. The fluid discharge apparatus is adapted with a barrel having internal spirally disposed baffles that induce rotation in the flowing fluids thereby producing a spiral flow. Cavitation results from the spiral flow thereby creating an axial region of low pressure that draws the gas radially inward resulting in a composite stream including a rotating stream of liquid surrounding a concentrically disposed stream of gas.
