Over the weekend I finally got to start my first reloading experience by cleaning the empty cases. Soaked the brass overnight in the hot water/vinegar/soap/salt solution, next morning found some of them looks decent, but looks like it can do better. So soak it again in another fresh solution, plus some semi-violent shaking. A few brass were mirror finish on the inside, but majority of them still have visible dark spot.
Today I gave in and bought a ultrasonic cleaner, and run the whole batch through it, again the solution came out dirty, but more than half the brass still look dirty inside.
I know i can run smaller batches in the ultrasonic to be more thorough, but my question is, how clean do the brass have to be? Clean enough so that a quick swab with a Qtip will still come out white?
