    I don't know what the reaction is with acetic acid and peroxide -
    it's fairly complex, I know that. The question is, are you simply
    pickling bare steel, or is this after welding or something? That is,
    does it have a flux on it? The nearest I can come up with is that
    you've made Prussian Blue - Iron Ferrocyanide. The problem with that
    is that it needs nitrogen (in solution), and nothing you say contains
    it. Prussian blue is not too far away in color from the windows bar
    across the top of explorer - deeper maybe, but about the same hue.
