[QUOTE="wonderman4, post: 1792133, member: 72101"] A paragraph from the link: [B]"The Chemistry[/B] Both metals used in brass cases (copper and zinc) are soluble in acetic acid (vinegar). The salts, copper acetate and zinc acetate, are also soluble. Zinc is more soluble than copper so it dissolves faster. In addition a galvanic action occurs that cause copper to be dissolved and then redeposited on the surface at the expense of the zinc. When you clean brass cases in a vinegar solution you change both the chemical and physical properties of the surface of the case. There have been comments about cases being too clean, primers hard to seat, deposits on mandrels, etc. When you change the surface by dissolving some of it and etching it these things will happen. Whether they happen to the point of being a problem becomes the issue. This doesn't mean that you shouldn't use acetic acid or that there is anything wrong with Jason's approach. Anything used to clean brass chemically is going to have some effect on the surface and it sure beats trying to get residue out of the flash hole of a 17 Remington with a brush." One of the links: [URL]https://www.6mmbr.com/ultrasonic.html[/URL] Bottom line is do not use pure vinegar for 6 hours. If you use a solution with 1 part vinegar to X parts water, that is different than just letting brass soak in vinegar for 6 hours. I use citric acid diluted with water and a little dish washing soap (Dawn). Citric acid is available at most any grocery store that sells canning supplies. [/QUOTE]
