I have a beautiful Olympic Arms Westerner 1911 - I've been told by the manufacturer that the color case hardening was done with the old school heat and quench method - it's NOT just a surface coating - does anyone know if an ultrasonic cleaner would damage the color case hardening effect at all ? I'd be using Lyman Turbo Sonic Gun Lube and Turbo Sonic Steel Cleaner in the ultrasonic cleaner to clean and lube the gun. THANKS !
