Good Afternoon All. I just aquired my grandfathers service revolver, and I'm looking for some advice on how to properly clean and polish this paticular revolver. I've never dealt with nickel plating and I've heard so many contradicitng techniques that I figured I would come to the source for the best and safest methods to clean and polish the finish without damaging it. The revolver is still in excellent condition with no major discoloration or pitting, just minor surface scratches and slight cloudiness towards the end of the barrel. Thanks in advance for any and all help.
