    ]Sadly it’s there forever.

    (To remove pitting you have to remove metal....)

    Typical, I lent a gun to a mate and it came back pitted. Won’t be doing that again.

    Remove barrel from rifle, cut off barrel where pitting is. Re-crown and you're good to go. If you want to save time dont remove barrel

    In all seriousness though, that's a bit shit of your mate.

    A very good point, as this had me fooled for a long time - barrels that never seem to come clean.

    This. I haven't got the "gunsmith eye" that apparently can see down barrels.

    Aqueous ammonia is an effective and inexpensive way of removing copper fouling, if/when that is required.
    Both mild and stainless steels are used in the manufacture and storage of ammonia, and while there can be corrosion issues, this depends more on other contaminants that are present than the ammonia itself. The reaction time-frames when this does occur are long. Reports to the contrary are good for selling the much more expensive alternatives. Do not store the ammonia anywhere near your brass.
    Here is a recent summary with references.

    I pretty well stay with Collings #90 and Ballistol.
