I cleaned up some brass tonight using a recipe I got off from the internet. I'm new to cleaning brass so any advice I can get would be great. I don't think they turned out too bad for a home made cleaning solution.

1 quart hot water
1cup vinegar
1 tablespoon dish soap
1 tablespoon salt

I soaked the brass for about 45 minutes stirring every 5 minutes. After that I rinsed the brass and baked them in the oven at 170°F for 30 minutes.

If anyone has a better recipe feel free to post it up along with any comments you may have.

I think they turned out fairly good. There is a little bit of residu at the base of the brass but nothing major.

Below are progress pics:

I've done that one, the phosphoric acid and the Lemi-shine version. The lemi-shine works a lot quicker with less prep, results are about the same.

Lemi-shine is a detergent additive for your dishwasher and it's almost all citric acid, which is what works to clean the crud out of and off the brass. Hot ( boiling works quicker)water, a little lemi-shine and about 10-15 minutes and you're done. The lemi-shine is supposed to react with the brass to form a protective coating which prevents tarnishing (as much) in the future.

These methods work on all but the cruddiest range brass, the blackest ones you will still have to polish some by hand or use a tumbler.

Here's a 32 page discussion on using Citric Acid (lemi-shine) on brass vs. other methods:

BTW, your brass turned out good! Nothing like having nice, clean brass to reload with. :thumbsup:

Dang if some of that brass don't look like .45acp!
