Hello, camoga

The only way to deoxidize the metal, is the electrolytic method, which desconpone the oxide in the most remote places, such as wells or "caries", where you can not reach with any abrasive. Of course the surface will not be polished, grayish, but the most important thing is that the corrosion is stopped, because there is no foreign body (oxide) on the surface. You will have to be careful with the inscription in the cannon, and make a test in another material, in order not to cause any damage.

Sorry for the translator.

Affectionately
