I am Just wondering what people use to put in with untreated corn cob media in their tumblers. I read somewhere that one guy was using car polish?

I know guys who used to use Brasso, decades ago. The downside of that is the ammonia in the cleaner. Supposedly, it attacks and weakens the brass.
 
I use Frankford Arsenal Brass Polish. A few dribbles really perks up the media. I also take used dryer sheets and cut them into smaller pieces and toss them in the tumbler. This helps collect lots of carbon that comes off the fired casings
 
I bought a 50lb bag of crushed walnut from Princess Auto. Very very dusty. Have to use a sealed lid tumbler indoors. My corn cob media is used with Simoniz polishing compound & Carnauba wax. Gives a brilliant (gold quality) shine.
 
Just switch over to stainless steel pins in a Lemshine or similar cleaning bath.

Your cases aren't as shiney or polished looking, but they're clean and the inside fouling is removed as well.

Just a quick rinse with hot water (so they dry faster) and you're finished.

You can use your original tumbler, which takes almost as long, or you can get a rotary tumbler, like those used by rock hounds.

The stainless pins are re usable and last forever.

I bought a five pound bag appx 15 years ago, when I was first informed about this on CGN. What's left will last a lifetime.

Lemshine is cheap and the whole process is much less messy/time consuming.
 
I tumble small quanities of rifle brass in corn cob, large quanities of brass go into the wet tumbler & SS pins.

I use a dryer sheet cut in ~1" strips to remove/clean the fines/dust/dirt/carbon from the media.
IMO, the polishing action is faster without the fines/dust/dirt/carbon in the media and the media lasts/performs longer without all the crap.

New corn media, I run the tumbler for an hour or 2 and remove dryer sheet c/w all the dusty fines.
Then I add a 'new' cut up dryer sheet, the brass and the Frankford or NU Finish polish additive. I replace the sheet as required, ie when media is dirty.

I have yet to find black ugly brass in my corn cob media.
 
Flitz makes a liquid polish for metal, plastic & fibreglass. A small dash is all you need.

For the ultimate in polish add 1/4 teaspoon of jewellers rouge with a teaspoon of paint thinner to your corncob. I did a mixed batch of brass & nickel 9mm cases a few years ago. I let the polisher run overnight and in the morning the cases were so shiny it was almost impossible to distinguish the brass from the nickel. Doesn't make the rounds shoot any better but they sure are purdy.:d

If you want to get rid of 95% that dust, take your crushed walnut outside on a windy day and just pour slowly from a wide mouth container into another one. very easy to regulate the pour so that the wind blows the dust past the receiving container ... takes 15 minutes to do a whole 50 lb bag .

Thank you for the info, after I do that I'll try cut strips of dryer sheet to get the last 5%.
 
I've been using 40/60 mix of Lyman Treated corncob, USED Bounce dryer sheets and a shot or 2 of mineral spirits and Nu Finish car wax. 25% Nu Finish.

Before you add the brass, run the tumbler for 10-20 minutes with the mineral spirit/Nu Finish mix.

Relpace the dryer sheets after every tumbler load.
