OK to reload badly tarnished brass?
- Thread starter djcantr
- Start date
I find the problem kind of resolves itself. The tarnished brass is much harder to find after being shot, just seems to disappear in the grass. I've got an M-1 carbine that throws brass like an outfielder, after a few trips to the range I just don't have any more tarnished brass.
Ammonia & Vinegar-Effect on Cartridge Brass
Ammonia & Vinegar should not come in contact with cartridge brass. Ammonia forms in nature, rotting veggies & moisture form it. Brass becomes weak. Google > "stress corrosion cracking" & "dezincification" Annealing will not repair the damage.

I have said many times.....
.. submerge a few tarnished cases into the glass container for a 7 days, the reaction of the case to the vinegar renders the case scrap..." In vinegar the case will turn pink/orange in a few hours, the vinegar goes after the zinc etc., etc.. and I said for a maximum of 15 minutes....and no one thought to ask WHY!

I question the truth of that. No one need fear what vinegar - or Lemishine (Citric Acid) - might do to his cases. A week long vinegar soak hasn't been suggested by anyone but in my experience - a test specifically done to see what would happen - submerged soaks of several days in straight white vinegar was harmless to the cases. Diluting vinegar simply means it takes longer to get the job done, otherwise adding water has no effect.
Brass isn't porous so the acetic acid in vinegar can't permeate the metal, it can only attack the oxidized dark colored surface. And straight vinegar certainly isn't a very strong acid anyway, we all eat the stuff in many salad dressings, pickles and other common foods.

A case cleaning solution including vinegar and salt was common for Army use as far back as the 1930s. Neither acedic (vinegar) nor citric (Lemishine) acids cause any problems with brass.
Ammonia IS a problem for brass, especially liquid, so don't let cases even sit in the fumes of that stuff. Not that the damage is instanteanous but it does embrittle the cases.

Then there is the Ol Army story, cleaned and stored brass 'in the old days' turned black, and when cleaning and 'pickling' brass in the Ol Army days time was a factor, the factor of time was 'for a maximum of 2 minutes'.

Sure, time is a factor for any large organization. So far as I know, the army never 'cleaned, pickled and stored old brass' but they did do a LOT of experimental shooting and reloading that required cleaned cases. I've never seen any military time limit on the arsenal's vinegar based cleaning solution nor any reason to think there should be a time limit due to chemical reaction and I doubt you have either.
Anyone wanting to see what a few days soak in pure vinegar (the highest possible strength) does should try it on a couple of cases for themselves, not listen to me or any other self styled 'web expert'. Drop 'em in, take 'em out when you wish; then flush, dry and tumble 'em, load 'em (with a mild load if you're apprehensive) and see how they work. I think you'll find they look and perform same as any others. ??
