Hello
As someone suggested above, oxidation is a continuous method, there is no passive oxide. The only way to deoxidize is the electrolysis, which removes even the oxide from the wells or cavities. This method does not affect the metal of the base, only the oxide. That of acids, still weak, like vinegar, also attack in clean metal. In this forum there is a thread about cleaning, at this moment I can not find it
