An apparatus (10) for washing eviscerated poultry carcasses (12) has a housing (11), a conveyor (15a) for moving the shackled poultry carcasses through the housing. A guide bar (24) tilts the poultry carcasses (12) from a vertical position for spraying by a first set of nozzles (23). The first set of nozzles (23) delivers a cleaning solution (100) at a sufficient flow rate and line pressure, whereby a portion of the cleaning solution (100) is deflected back out the rear opening (12d) of the poultry carcass (12).
