brass polish

[secret.asian.man]

i recently ran out of my bottle of Dillon Rapid Polish 290 that was given to me by a friend. i like the stuff but it's about $1.80 an oz shipped and the only place that sells it is Dillon (according to google shopping). is there a cheaper, good quality alternative, what do you use? or is $1.80 an oz the going rate for ammonia free brass polish? i have a Hornady Case Tumbler and using crushed walnut media.

thanks!

I couldn't tell you down south, but I know up here we have stores that do sell it besides Dillon.

An alternative is to use Nufinish car polish. Pour it into the media as you did the Dillon.

is there a downside to using brass polish with ammonia? cause i use brasso and i believe it contains ammonia, but my cases are REALLY shiny after tumbling

I use Brasso as well. Since it does contain a minute amount of ammonia, I doubt it's harmful since it is on the market as a brass polishing product. If anything, it's just enough ammonia to remove the tarnish. Rinsing brass in pure ammonia is where I'd be concerned.

OP, some people use NuFinish with great success, even though it's made for cars.

Been using NuFinish for years. Just add it to your media and run tumbler for about 15 or so to work in than away you go. I also use a little bit in corn cob for a final bling run!

NuFinish works great and is inexpensive, available at your FLAPS. I bought some Dillon polish with my last order from Brian Enos and it works well, but frankly when it is gone, I will go back to NuFinish.

Yes there is a problem with using a product with ammonia in it to clean your ammunition brass. ammonia weakens brass and enough of it will cause it to crack.

http://en.wikipedia.org/wiki/Brass

"Brass is susceptible to stress corrosion cracking, especially from ammonia or substances containing or releasing ammonia. The problem is sometimes known as season cracking after it was first discovered in brass cartridge cases used for rifle ammunition during the 1920s in the Indian Army. The problem was caused by high residual stresses from cold forming of the cases during manufacture, together with chemical attack from traces of ammonia in the atmosphere. The cartridges were stored in stables and the ammonia concentration rose during the hot summer months, so initiating brittle cracks. The problem was resolved by annealing the cases, and storing the cartridges elsewhere."

I buy my Dillon polish from Phillips Wholesale in Covina. That may be too far for you to to drive but there must be other places that carry it. Call around.

Avoid polishes with ammonia if possible. It does remove tarnish and is generally safe for ornamental brass which is usually less than 15% zinc and has little residual stresses from fabrication. However, cartridge brass is 30% zinc and has substantial residual stress from the cold drawing process used to form the cases. The ammonia accelerates stress-corrosion cracking, shortening the life of the brass. In severe cases, the SCC can ruin a cartridge just setting there. There is a well known (to use engineering geeks) case from the 1920's were the British Army stored brass cased cartridges in a stable in India during the monsoon season. The action of the ammonia in the air from horse urine combined with residual stresses from the cold drawing process caused severe cracking in the brass -- especially at the crimp.
