You have seen them. The shining copper on an old gun. Can you, and how do you reverse it? Thanks!

A thin wash of copper is often an indication that a gun has been cold blued. Sometimes, a cold bluing job can be detected by a copper smell. A dilute acid will remove it, but you have to be careful that the acid does not etch the steel, unless you desire a matte finish. You could also look into reverse electroplating with the copper plated frame as the anode, and have it thus removed and plated out onto the cathode.


A true sign of mental illness is any gun owner who would vote for an Anti-Gunner like Joe Biden.
