Cleaning inside of cases w/Citranox: Problem

[ronas]

I can not get the inside of cases clean with ultrasonic cleaner, with heater, using Citranox. I use 20 ml with 1 liter of water. Outside of cases clean very quickly.

Cases are 5.56 fired 4x and 308 cases fired 7x.

Higher concentration of Citranox does not seem like a good idea.

Anyone else have this problem or have any suggestions other than clean inside with a q-tip. The q-tip will get the residue out but what a time consuming pain. Tried wire bore brush but no real success, still had to use q-tip.

The inside is, what it is. Were you trying to make the inside as clean as the outside?

Stainless Steel media tumbling will clean them out perfectly. Check out Allied Armory's threads on the subject.

Not that you want to make this a regular practice, but run it again with only about 10 cases in the tank. I'll bet you'll see clean cases inside and out as well as clean primer pockets.

Unless you have a multi-hundred dollar industrial strength cleaner with a large transducer, ten to twenty 45ACP cases is about the limit for true ultrasonic cleaning with those Hornady/Lyman/Harbor Freight cleaners.

My tests showed 18 45ACP's with four 8-minute cycles was the limit for pure ultrasonic cleaning with 1-2 drops of Dawn dishwasher soap. Cases needed to sit separated, not stacked on top of each other. The pictures of a full basket of .223's coming out of a (fill in the blank) cleaner is the result of nothing more than mechanical agitation in the proper cleaning solution.

Yes these are used to make rounds to shoot 800 yards so they need to be as consistent as possible.

I read somewhere that the stainless media can peen the case mouths, not something I would want to happen.

It theoretically could peen case mouths but it doesn't. Also, many records have been set by brass that is never cleaned more than being wiped down on the outside. Youll have better results spending your time annealing than youll ever have with cleaning the insides of cases

I do that too with a Bench Source Machine.
