A friend told me he is about to start cleaning his brass with an ultrasonic cleaner, anyone do this?

It would be nice to clean the inside as much as the outside, and to clean the primer pocket well, but not sure of any real substantive benefits.

Anyone?

I have thought about doing that as well.

I saw this topic over at Snipers hide.  This way looks pretty interesting as well.  It appears to really get the brass clean.  http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=1153883&page=1

I've thought about it...can't remember, but there was some solution people found to be the best. Have you checked out http://www.6mmbr.com/ultrasonic.html
and http://www.brownells.com/.aspx/lid=12779/GunTechdetail/Ultrasonic_Case_Cleaning?

per case cleaned its expensive, unless you'll be doing thousands of cycles. A phosphate buffer solution (phosphoric acid) works best in neutralizing the ammonia salts, and the ph doesn't get out of control. (dissolve the brass or weaken it). Say something like 30 ml per liter with just a dash of Joy dishwashing soap to loosen oil. Let air dry, ,or drop in some old pillow cases for 20 mins. in the dryer.

I see Hornady just came out with a ultra sonic cleaner.

I am leaning more toward the stainless steel media in a tumbler, seems easier and less baby-sitting.

I'll wait till a friend runs his ultrasonic a few times, maybe I can buy his cheap.

in the end, enough time in the shaker gets it done, so no real hurry, just don't love the dust and simpler is better.


Anyone tumble after loading, to get the lube off the cases?  I haven't been doing that, might try it.  I usually just wipe them down, maybe my precision and accuracy will increase significantly!

Never heard of that...wonder how much it would peen (and work-harden) the brass.

I drop a couple fabric softener sheets cut up into quarters into the separator. A lot comes off on to those.

As you know, you don't want any lube, grease or other build-up in the chamber. That's for sure. I think just wiping them down is enough though. And tumbling would just introduce walnut dust into the chamber, mixing with any gunk. Plus, just sounds like more work.

I cannot quote chapter and verse, but I read somewhere that tests done on internal case cleaning did not improve accuracy.

I use to run mine for anything from 4 to 8 hours. A lot depends on how new or clean the medium is.
 
I do not use a case tumbler any longer, but use citric acid (1 teaspoon in 2 pints of water)

No ultra sonic. I dump the cases into the solution for about 15 secs, then rinse them in clear water and let them dry.

Ok i read the article, intersting. 
 
So you take a spent round, and go straight into a solution and it cleans it good?

I use crushed walnut hulls to clean the fired brass, and then through in several damp rags in the seperator after I have seperated the media from the brass to remove the dust from the brass.
After loading, I tumble the rounds in corn cob media (Lyman treated corn cob media) for a couple of hours to remove the case lube (Dillon case lube), and it doesn't leave much dust.

The outside area looks nice and shiny.The primer pocket still has to be cleaned manually.

Citranox was the stuff I was thinking of. From what I read a gallon is about $50 with shipping and a little goes a long way. (8shots' comment on citric acid reminded me). It would be worth checking out.

I bought a Gemoro 1.2qt ultrasonic cleaner, which is the same thing as the Hornady, only $25 cheaper. Used the diluted case cleaner/distilled water solution and got really good results. My main concern was the interior of the brass and they came out really clean. The only drawback I found with the unit was that it had an 8 minute timer, and to heat the solution and clean the 125 pieces of .204 brass it took over an hour. I did some reloading at the same time so was able to reset the timer each time that it ran down. Drained the solution, did a cycle in distilled water, then finished drying the shells on a cookie sheet in a 240 degree oven after my wife had used the oven to cook supper.

BeltFed,
Did I read that correctly? You indicated you tumble live rounds. I'm just curious? I've always been instructed by the experts this was very dangerous. Did I miss something?

Yes you read right. They are not tumbled in a rotating barrel like a rock cleaner, but are cleaned in a Dillon tumbler which is a vibrating tumbler so nothing is falling or developing enough energy to detonate a primer.
