bzt Posted November 23, 2015 Share Posted November 23, 2015 So, I have about 6000 peices of 9mm brass. If I clean them all now, how do I keep them from tarnishing? Link to comment Share on other sites More sharing options...
Miranda Posted November 23, 2015 Share Posted November 23, 2015 You send them to me and I keep them busy... How determined are you to keep tarnish at bay? bag them with a desiccant and an oxygen getter should work... put some wax in the tumbler for that new car shine? I think you only need to keep them dry. miranda Link to comment Share on other sites More sharing options...
GrumpyOne Posted November 23, 2015 Share Posted November 23, 2015 If you have one of those food saver things that sucks the air outta ziplocks, try it...otherwise, just 5 gallon bucket with a good lid. Link to comment Share on other sites More sharing options...
atbarr Posted November 23, 2015 Share Posted November 23, 2015 Shoot them! Link to comment Share on other sites More sharing options...
Steve RA Posted November 23, 2015 Share Posted November 23, 2015 If you dry tumble them with a lot of Nu-Finish in the corn cob or walnut hull it will keep them from tarnishing somewhat longer but they will eventually tarnish. Link to comment Share on other sites More sharing options...
dave33 Posted November 24, 2015 Share Posted November 24, 2015 (edited) Give them a quick bath in very hot citric acid. Doesnt need to be a super high concentrate, a couple teaspoons in a quart of water. Only need to be in there a couple minutes, then a quick rinse in fresh water should keep them shiney for a long time. Citric acid passivates or protects the brass, so if you store them for a real long time that is good. You can get citric acid from a number of places, I get mine at Walmart in the canning section.

9x45 Posted November 24, 2015 Share Posted November 24, 2015 Yes, shoot them. Look at these cases, there is no difference in accuracy, only looks, don't judge a round by it's looks.... Link to comment Share on other sites More sharing options...

I used to do the same thing, except I didn't do the final rinse. I took them straight from the hot citric acid bath, did a quick towel dry, and put them into the food dehydrator. It definitely helps maintain the shine for a long time. Link to comment Share on other sites More sharing options...
Dirtchevy841 Posted January 1, 2016 Share Posted January 1, 2016 YeAh a little more wax but will tarnish eventually. Link to comment Share on other sites More sharing options...
ToddKS Posted January 1, 2016 Share Posted January 1, 2016 (edited) Fresh clean corn cob, Nufinish polish, and an overnight run. Put in a bucket with a lid when done. Will stay bright for a long time. Walnut cleans good but soes not polish as well. Long run time is key.

Beastly Posted January 1, 2016 Share Posted January 1, 2016 A light coat of Hornady One Shot will leave a waxy protective coating on the brass. Thi is what I use after wet cleaning and drying. Don't over-do it. Same with a home-made lanolin/alcohol lube but this tends not to aeresolize as well as the one shot and can leave a greaser coating. Minimize contact with moist or humid environments. Keep brass in semi-conditioned space or use freezer bags, sealed buckets, etc. Link to comment Share on other sites More sharing options...
Dirtchevy841 Posted January 1, 2016 Share Posted January 1, 2016 Buddy uses Dillon case lube after he loads his 9mm and he says they stay bright a while longer. Don't think I want to waste my lube for that. I shoot what I load before it starts to tarnish. Link to comment Share on other sites More sharing options...
acoop101 Posted January 25, 2016 Share Posted January 25, 2016 Once they are clean the cases are clean. If they are super shiny that is not the end of the world they will still load fine. That said what kind of timeframe are you looking at to use all this brass? Sent from my XT1080 using Tapatalk Link to comment Share on other sites More sharing options...
Kaldor Posted January 28, 2016 Share Posted January 28, 2016 Define tarnished? I have wet tumbled cases, dried them, and put them in a plastic box with a non air tight lid over 18 months ago. Is the brass as shiney as the day I cleaned it? Nope. Will it load and shoot just fine? Yep. Unless it is starting to turn green or black, I wouldnt worry about it.

9x45 Posted January 29, 2016 Share Posted January 29, 2016 That said what kind of time frame are you looking at to use all this brass? Should only take 3 months to go thru 6K of 9mm. Link to comment Share on other sites More sharing options...
acoop101 Posted January 29, 2016 Share Posted January 29, 2016 I wouldn't worry about it, even if that tarnish they are still clean, load then shoot then Sent from my XT1080 using Tapatalk Link to comment Share on other sites More sharing options...
Bob DuBois Posted January 29, 2016 Share Posted January 29, 2016 If it's range brass, once cleaned spend a little time inspecting after cleaning. I use a box. plastic tray, and three of the Lawman plastic trays from factory ammo. Pour a hand full of brass into the box with the factory tray in it most will fall base down. here look for berdan primers splits, cup marks or trash in the case. Use another factory tray like a primer flip tray then look at the bases. I load on a 650 so I can't swage brass, chunk any that are swaged, military or any other reason, I don't keep odd headstamps. Military cases have a smaller case volume. you can turn the factory tray sideways and look for 380's or Supers that found their way into the tumbler. I tumble with Nu Finish or Turtle auto polish in corn cob media, inspecting after tumbling. Place the inspected clean brass in a five gallon bucket with a lid in the loading room. That way I have plenty of good brass when a loading session starts. Link to comment Share on other sites More sharing options...
