The aesthetic appeal of case hardeing colors is a mystery to me, but to each his own. Does anyone know of a reliable way to hasten the fading of the blue-brown to the patina that is revealed after case colors fade? No, not the coin finished stage, but that soft grey which for my taste is about as good looking a metal surface as can be.
I tried steel wool, gentle abrasives but cannot get that soft sheen. I guess what is needed is some polite alternative to human sweat. Well, it is a better alternative to some other body fluids mentioned above.
