Re: Neat Vinegar for cleaning shell cases???
For a while I was cleaning cases with vinegar, salt, and some dawn mixed in. I would mix it with some hot water and let them sit for a few hours and they seemed to come out okay. I always rinsed them well after soaking them and I never had any issues with case weakness. The brass cases have an oxide layer that forms (gives them a dull color), and that is what the acid will react with. It doesn't (a weak acid) react with the brass itself.
I broke down and bought a Hornady tumbler with some corn cob media. Now my brass is really shiny, and I don't have to annoy my wife by drying the brass all over the place!
