    No, it may take some crud off, but not verdigris.

    Verdergris is crud (IMO), and it will likely loosen it, but it will probably need some help to remove it entirely. All IMHO...Mike

    Depends on what you mean by "verdigris".

    Loose crud and surface grime, yes. Even greenish crud which is what I call "verdigris". Yes.

    Active corrosion, no. If corrosion has pitted the metal, there is no reversing it. You can't fix pitting.

    However, the mineral oil certainly improves the appearance.

    I like mineral oil better than olive oil, and Vaseline better than mineral oil.
