As the title states, what does everyone use for brass? Steel,stainless steel?

I have one of those. It’s ok but I have better luck with a vibratory with walnut shell. I dump a little Brasso in too. Run it overnight, cases like new and don’t have to dry the water out of them.
 
Looks like clean and shiny is the way to go for brass.

How about steel?

I have no clue how old that article is but I know I have done the clean and shiny method for years and years from it. Great way to do it - my only change is that I load the brass in the container neck down so as any dirt crud falls down and out.

Same question to you as above post.

I've been trying to get these puppies clean all day! First pic is before cleaning, the rest are after cleaning. It liked baked on the black around the necks. I just threw them in the tumbler to see if I can get that crud off. The inside of the cases are super clean!

Ultrasonic is a PITA, but it appeases my OCD. I don’t care about shiny brass, I just want a thorough clean. (I haven’t tried stainless, but have always been curious. Although, I’ve wondered if it would harden the brass?) ... anyways, I use 1-2 tablespoons of anhydrous citric acid (buy it on amazon. I think it’s from DUDA Energy) ... and a couple drops of dish soap. I start by standing the cases on end (primer pocket down) for a cycle, then lay the cases on their side with the case necks over the transducer for a cycle.
... I’m running a RCBS, and need to upgrade. Cases that sit on top of the transducer clean up quickly, but those that sit off to the side of the transducer take FOREVER.... so I have started running smaller batches (25 cases at a time) and periodically rotate them so they all get time in the sweet spot.

... hopefully that makes sense?

After 6 hours in the tumbler with polishing agent

I haven’t used the ultrasonic before, but I have tried the stainless steel media with the soapy solution and it worked really good, getting the inside nice and clean as well as the primer pockets.

However, I have since gone back to just a regular vibratory tumbler due to the amount of time it takes to do the wet media tumble. I hated having to dry my brass in the oven and then was always a bit nervous about if all moisture was out of the inside of the case. And then I would have to dry the media as well.

Went back to vibratory so I can just tumble and load!

Adding vinegar in the ultrasonic will help with cleaning quite a bit.

You just have to then rinse it with some water/baking soda to neutralize the vinegar or it will leave a tarnished looked.

Question, do you reuse your Birchwood Casey cleaner solution? I just picked some up and was reading the instructions and it says it is reusable. A small bottle also doesn’t make a whole lot.

No, I haven't. I don't reload large numbers of cartridges, so I use it once.
 
My ultrasonic never worked that great I bought a harbor freight rock tumbler and stainless steel pins. I put in lemishine and couple drops dawn with warm water. In 2 hours perfect brass in and out primer pockets perfect just rinse and let air dry.
