Lemi-shine = citric acid
Taste it, sour as hell.
I use about a gallon of water, 5lbs of tumbling media, 1.5oz of Armoral car wash and ½ of a 9mm case of Lemi-Shine and tumble for 60-120 mins depending on quantity.
Nope.Go and taste Lemon Pledge and tell us what you think.... go on, TASTE IT!

I like my cases oxidized. Gives 'em that classic look.
Some years back there was a big discussion on "cold welding" in Precision Shooting magazine. This is when you take a shiny clean bullet, load it into a shiny clean case, and then sit the ammo up on the shelf for a few years. Then when you shoot it, the pressures go WAY up because the case doesn't want to let go of the bullet any more. I can't recall if any guns were destroyed.
Anyway my case necks are always nice and dirty. I might brush them out a bit, that's all.

Brass and copper are not dissimilar metals
Cold welding of bullets. | Ask The Gunwriters | 24hourcampfireFor those of you who have subscribed to Precision Shooting for a while, Randolph Constantine wrote an article in the 1990's about his experiences with "cold welding". It was entitled something like "Cold Welding Can Ruin Your Day". Constantine is/was a highpower competitor and also a rocket scientist who observed older handloads with drastic elevation problems. He sought the source of the problem and diagnosed the cold welding phenomenon.
The Precision Shooting authors are pretty damn smart about firearms. I recall that the concept was not entirely accepted, although my memory is not all that reliable. There were some claims that the military used to load with a tar-like substance in the neck to avoid this problem.
That's the problem. It happens with similar metals, not dissimilar ones. It is not a corrosion process, unless I'm mistaken.
I don't know why all new ammunition doesn't have the same problem, but we may be making some assumptions that are not correct (that no coating is present to inhibit the process in new ammo). Also it's apparently very important that the brass is very clean; sitting a few days in a bin may bring enough oxidation to prevent it.
You can google "cold welding" and see some discussions, e.g.:
