Thread: Tumbler or Sonic cleaner

Stainless pins in a wet tumbler makes brass shinier than new

Dry, then graphite powder the necks

I have found a tumbler with SS pins to be great for rejuvenating surplus brass and really filthy stuff. As observed above, the SS tumbler is hard on case mouths. For general reloading with already prepped brass, I like to keep it simple and 30min in a vibe tumbler with walnut (before de-priming) is what I do. I use a shot of nu-wax liquid polish as a cleaner and protector. You can get non-branded vibe tumblers way cheaper from a few different places, the reloading branded ones are no different aside from price.

I have found sonic cleaners to be more hassle than they are worth for brass. Very handy to have for gun parts and other stuff (tip: use snap lock sandwich bags and fill them with whatever fluid you are cleaning with and the part your cleaning, then you keep the water in the sonic cleaner clean and don't need to fill the whole thing with de-greaser/mineral spirits / IPA, just a little baggie)
