I recently acquired a 1972 nickel plated Colt Detective Special. I like this revolver and was wondering if anyone had any tips on how to clean up the finish? I have silver polish and brasso, but wasn't sure what to use/what works the best? I always soak my guns in machine oil before tackling any major cleaning issues. The finish is about 85%. It is a really nice piece from the era, but I just want to make it a little nicer. I do not want a "high polish" or "bright finish", just free the nickel finish of some of the blemishes. Thanks in advance for any assistance. Yall be safe.
