    I 've been using the froglube solvent on my firearms for a few years and have gotten good results.

    Due to the electronegativity of copper, it reacts, but iron and chrome will not, at least to an extent to worry about.

    Many bases are very aggressive with metals, most notably cyanide compounds.
    Ammonia is not an ion. Ammonia will react with water: NH3 + H2O yields NH4+(aq) and OH-(aq), until equilibrium is reached.

    I expend tremendous amounts of energy and time merely to be normal.

    This is the email I received from Hoppes themselves when asking about #9 on chrome bore:

    Prolonged contact with nickel or chrome is not recommended with any Hoppe’s solvent. Most steel are flash plated with copper because the chrome/nickel plating adhere better to copper than the bare steel. If there is even the slightest scratch, nick, void etc. in the chrome/nickel platting, hoppe’s solvents will penetrate the flaws and dissolve the underlying copper substrate and cause the chrome/nickel plating to chip and peel further.

    Until they come up with a better smelling solvent, I'll stick to Hoppes. Perhaps a Hoppes #9 aftershave?

    I'd like confirmation from and industry insider, but I'm willing to bet dollars to pesos there is no copper in a bore. All copper solvents would destroy cl barrels if that was the case.

    Copper undercoats are generally used for decorative coatings, not industrial coatings.

    Ammonium ion, i think it was an auto correct fail.

    And yes, the ammonium hydroxide is what oxidizes the copper.
