A chemical vapor deposition reactor and a method of wafer processing are provided. The reactor includes a reaction chamber having an interior, a gas inlet manifold communicating with the interior of the chamber, an exhaust system including an exhaust manifold having a passage and one or more ports, and one or more cleaning elements mounted within the chamber. The gas inlet manifold can admit process gasses to form a deposit on substrates held within the interior. The passage can communicate with the interior of the chamber through the one or more ports. The one or more cleaning elements are movable between (i) a run position in which the cleaning elements are remote from the one or more ports and (ii) a cleaning position in which the one or more cleaning elements are engaged in the one or more ports.
