[QUOTE="TracySes23, post: 1319325, member: 52763"] For the past couple of years I was concerned about what looked like carbon deposit on neck & about 20% adjacent to the shoulder of my Lapua 22-250 brass. Citric acid, tumbling did nothing. I could use 0000 still wool which worked but I wanted to avoid using anything abrasive simply because I have a tight-necked chamber which requires neck-turning to a .012" wall thickness in order to get a loaded cartridge to chamber & allow a .002" total clearance. This is a common practice for bench-rest competitors. Acetone & lacquer thinner didn't work either. Everything I looked at seemed to warn about being used on copper or brass. These cases have always worked fine, they sized okay & other than appearance I had no problems other than being anal about this tarnish. I stopped worrying about it for a couple of years, but yesterday I decided to look at everything I had that could possibly be used. Finally I found something that remained from my motorcycling days. It's called NEVR-DULL. It's a cotton wadding material impregnated with mineral spirits - petroleum Hydrocarbon. This stuff works GREAT! 40 cases later the necks of my brass looked new! Afterwards I wiped them clean w/paper towels & soaked them in hot water w/dish-soap to be sure there was no trace of NEVR-DULL left as a precaution. Here's the web page for NEVR-DULL..... Nevrhttp://www.nevrdull.com/MSDS.htm As an after thought, I have no idea as to what caused this dark almost black tarnish, unless it was caused by a new bore cleaner I began using a couple of years ago. I won't mention the name since I've stopped using it. I've began using again what I used previous to this problem which was Wipe-Out. If this problem doesn't arise again while I only use Wipe-Out I might mention the name of this product. If the carbon appearing tarnish returns using only Wipe-Out I'll be back. [/QUOTE]
