Citric acid brass cleaner

[sharkey]

Im using the Lemishine and Ajax wash mix with hot water and pins in the larger Franklin Armory Tumbler. The last couple of washes have been 800 or so decapped 45acp cases, run for 3 hours. Ive dialed back the detergent and the Lemishine because I was getting slightly tinted orange brass (too much acid leeches the bismuth or zinc out) used with copper to make the case. 1/2 of a 9mm case of Lemishine and two squirts of Ajax dish detergent to a little more than one gallon of hot water. I limit the pins to 1 cup. Cases come out looking new.

Pour the tumbler into a bucket and capture the pins with an old speaker magnet. The pins seem to remove the primer lead that tarnishes the inside of the case near the flash hole.

I have used critic acid for years, picked it up off you tube. Works great

Thanks for the info!

Been using it in place of dilute muriatic acid for dirty brass. 53¢ an ounce bulk food section.
Works wonderfully.

Just noticed this thread, I don't usually have brass tarnished enough to need anything other than Nu Finish in the tumbler. When in the Navy, I cooked for a while, and found out the duty of the cooks was to keep the ships bell shined! When it was my turn, my buddy said "no problem, just get a pan of warm water, and pour some Cool-Aid mix in it", sure enough, I sponged the bell after splashing it with the Cool-Aid mix, and it was bright brass! The warming trays we served food from were above copper pipes covered in water, once a week we added some Kool-Aid mix to the water, and kept the copper shining.
Later years, I had a brass prop for my boat that my buddy thought we ought to shine, I told him about the Cool-Aid, he didn't believe me, he ended up buying the beer!

Just don't drink the Kool-Aide after you soak your brass in it. Has a bit of a tart taste to it...

Lemon unsweetened cool aid works good. I keep a 2 lb bag of citric acid at camp. Right now I'm doing some pistol brass while sitting on the deck
