I wanted to polish some 9mm brass in my vibratory tumbler (corn cob media) using Frankford Arsenal brass polish. It had been a whils sence I had added any new brass polish to the media so I started it vibrating and squirted a generous amount in and let it vibrate with no brass fro about five minutes.
That was not enough as many of the pieces of brass have black spots on them. Any ideas on how to clean them?
Thanks
