I started my cartridge collection about 30 years ago, but it has been stagnant for a very long time. In the past few years I've been adding to it, but now as I am prepping my spot for my new reloading room build, I am wanting to resume my collecting and display my cartridges.
What's the best way to clean up and get rid of the tarnish on these rounds? Most of mine are nothing special so that's of no concern, but I would like for them to be nice. Anything other than corncob in the tumbler?
