A method for removing concrete from the interior surfaces of a concrete mixing drum, the drum including an open end and at least one interior surface facing away from or opposite the open end, an elongate probe having a longitudinal axis and an axially extending forward end being inserted into the drum through the open end thereof; and at least one fluid nozzle being mounted to the probe in position for discharging a stream of fluid against the at least one interior surface facing opposite the open end under sufficient pressure to dislodge accumulated concrete therefrom as the probe is moved in the drum.
