Embodiments of the invention generally relate to apparatus and methods for cleaning chamber components using a cleaning plate. The cleaning plate is adapted to be positioned on a substrate support during a cleaning process, and includes a plurality of turbulence-inducing structures. The turbulence-inducing structures induce a turbulent flow of cleaning gas while the cleaning plate is rotated during a cleaning process. The cleaning plate increases the retention time of the cleaning gas near the showerhead during cleaning. Additionally, the cleaning plate reduces concentration gradients within the cleaning plate to provide a more effective clean. The method includes positioning a cleaning plate adjacent to a showerhead, and introducing cleaning gas to the space between the showerhead and the cleaning plate. A material deposited on the surface of the showerhead is then heated and vaporized in the presence of the cleaning gas, and then exhausted from the processing chamber.
