I am trying to determine the best routine for cleaning cases. I will begin with the worst case, my plinking brass which starts its life for me as range brass. I start with a good rinsing to remove dirt and grass. I then soak them in water with a cup or so of vinegar (not an exact science.) then comes decision time. I have all three of the major cleaning tools, but always have to think about which to use, and when.</SPAN>
As a starting point, I will point out my observations of the three tools.</SPAN>
Vibrating with treated walnut shells. </SPAN>
Ultrasonic </SPAN>
Stainless tumbling </SPAN>
I have recently been following the vinegar solution bath with rinsing and drying, depriming, full-length sizing and trimming, swaging the primer pocket and then tumbling. My reasoning for cleaning at this point is that it removes the lube which makes it easier to hold stationary while chamfering the neck and normalizing the primer pocket if that is done, it also cleans the primer pocket which is now empty. The downside to cleaning after depriming is that “something” often gets stuck in the flashhole (unless using ultrasonic.) I then chamfer and debur the neck and think about normalizing the primer pocket… NAH, it’s range brass, so only useful for plinking or barter when the SHTF.</SPAN>
If I choose to vibrate, I will probably follow it with untrasonic to clean the primer pockets. That is why I have mostly switched to stainless media tumbling.
For my precision brass, I have been depriming, full length sizing (gas gun) and trimming, stainless media tumbling (not concerned with possible work hardening because I plan to anneal every third firing,) and chamfer/debur the neck and renormalize the primer pocket (I had thought it was a one-time thing, but some brass supposedly flows each firing.) Then I sort it in .1gn lots. I sort and store them in two Stack-On 39 drawer storage cabinets (DSB-30) ($20 each at Lowes) The small drawers work great for sorting and storing (since they come out easily,) and I use the 9 large drawers for holding fired brass until I start over.</SPAN>

Vibrating with treated walnut shells. </SPAN>
- Very loud, </SPAN>
- Does not seem to clean inside of brass, </SPAN>
- If deprimed, walnut shells get stuck in every third flashhole on average</SPAN>
- Gets wife upset due to red rouge powder all over bathroom floor</SPAN>
- Highest brass volume, but not by much</SPAN>
- Will do little for appearance of really grungy range brass</SPAN>
- Dry process</SPAN>
Ultrasonic </SPAN>
- Cleans inside and outside including primer pocket</SPAN>
- Nothing to get stuck in flashhole</SPAN>
- Lowest brass volume</SPAN>
- Relatively quiet</SPAN>
- Production further limited by temperature, which rises with use. My Hornady unit cuts off at a certain temperature and refuses to budge until temp reduced.</SPAN>
- Does good, but not great job with really grungy range brass.</SPAN>
- Uses water</SPAN>
Stainless tumbling </SPAN>
- Cleans inside and outside including primer pocket</SPAN>
- If deprimed, Stainless pins get stuck in every 30 to 40[SUP]th</SPAN>[/SUP] flashhole on average</SPAN>
- Longest media separation process of three</SPAN>
- Relatively quiet (about the same as ultrasonic, much quieter than vibrating)</SPAN>
- Gets brass SO SHINY my wife thought of making into jewelry, lol</SPAN>
- Moderate brass volume</SPAN>
- Uses water</SPAN>
