A method for removing residue deposits from a reaction chamber includes supplying a cleaning gas into the reaction chamber via direct delivery from a remote plasma source (RPS). The cleaning gas forms a plurality of gas flow streamlines within the reaction chamber. Each of the streamlines originates at an injection point for receiving the cleaning gas and terminates at a chamber pump port coupled to a fore line for evacuating the cleaning gas. A flow characteristic of the cleaning gas is modified to redirect at least a portion of the gas flow streamlines to circulate in proximity to an inner perimeter of the reaction chamber to remove the residue deposits or to enhance the diffusion of cleaning species to surfaces to be cleaned. The inner perimeter is disposed along one or more vertical surfaces of the reaction chamber that are orthogonal to a horizontal surface including the injection point.
