    Default Aluminum pen

    I’ve got a Montegrappa Moon Landing pen and I’ve got some tiny black spots appearing on the section which is matte aluminum. At first I thought it was ink but I couldn’t clean it off with vinegar, alcohol or mineral spirits. I’m thinking that it could be the aluminum blackening from oxidation, I’m wondering if anyone has any experience with this.

    Wasn't this already answered in the "Ink Stain" topic in the General Inky Goodness forum?

    Wikipedia: Some aluminium aircraft parts, architectural materials, and consumer products are anodized. Anodized aluminium can be found on MP3 players, smartphones, multi-tools, flashlights, cookware, cameras, sporting goods, firearms, window frames, roofs, in electrolytic capacitors, and on many other products both for corrosion resistance and the ability to retain dye. Although anodizing only has moderate wear resistance, the deeper pores can better retain a lubricating film than a smooth surface would.

    There’s more spots appearing around the parts that my fingers contact the section even though it hasn’t had contact with any ink of any sort. Which is why I’m asking here if it could be a result of corrosion from my sweaty hands

    Yes it was already answered in the Inky Thoughts forum.
    Ron has already said that it isn't necessarily caused by ink.
    I think that the best people to answer the question are the manufacturers. If it had been my pen they would have it back by now to investigate the problem.
