It would be interesting to try an oxygen plasma on a carbon coating to see the effect.

Wikipedia has two articles listed as Plasma cleaning and Plasma ashing that may be useful. Cleaning carbon is easy. Removing boron may be harder. An aggressive oxygen plasma could damage the metal electrodes so they would have to be protected. Argon or helium plasmas may be more practical. This has been mentioned in other posts about removing contaminants from the chamber.
An automated cleaning system could be designed for a commercial unit.
