Titanium oxide removal after hermetic sealing


Does anybody know a way to remove the oxide produced when firing a glass-to-metal seal made from titanium? The unwanted oxide or non-conductive film prohibits a mating connector from making an adequate ground connection on the threads of the glass-to-metal connector. I can remove the oxide off of most of the connector body by post machining but getting the oxide off of the threads is a problem. Help!

Any info would be greatly appreciated.

Thanks in advance.

Grit Blast. The only other method involves aqueous fluoride and may decompose the ceramic.
