Cleaning cases

[Jezzer]

I cleaned all my brass for years with walnut media then decided to give ultra sonic a try. I had very mixed results with US so ended up going back to walnut media. A year or so ago I bit the bullet and spalshed out on tumbler with stainless steel pins from spud1969..... well I've now sold the US cleaner and the walnut media system and am 100% happy with the stainless media tumbler.

When I tumbled my cases the insides were left reddish. I found that neck expanding was more difficult with the media dust inside the cases (mostly pistol calibres). Anyone else get this?

Thought I'd post update regarding my case cleaning with ultra sonic cleaner. The one I bought holds 750ml. of water, so its only a small unit. I've used it for a couple of months now and very pleased with results. First ultra sonic cleaner only lasted for a couple of days before it failed but I'd bought it locally and returned for replacement and the second one has worked perfectly ok. The speed the cases are cleaned is very quick, only 10 minutes or so, and the pockets don't need cleaning seperately and there's no tapping each case to get the tumbling media out.
A friend bought an ultrasonic cleaner after seeing the results of mine and was initially disappointed, however he used it without the citric acid. When he used the acid his cases were very clean as well. So the acid obviously does something.
I've got a black powder revolver and put the cylinder, hammer etc. in the ultrasonic cleaner and they come out spotless. That was something I hadn't considered in the beginning, so overall very pleased. Within seconds of starting cleaning the liquid around the items being cleaned gets cloudy, I can see the dirt being lifted of. At the end of the cleaning cycle the liquid in the tank is so dirty I can't see through it.
I appreciate I don't fire a massive amount of ammunition so I can see the tumbler with pins could be the way to go if you do get through lots (or a larger ultra sonic cleaner) but for what I do at moment it does all I want it to.

Do we have a equivalent to Lemi-Shine?

Citric acid I believe - available on Amazon.

A bit of googling will come up with concoctions people use in lieu of lemi shine.
