Walnut vs corncob media

[1sailor]

I've been using corncob media to keep my brass clean and it does a pretty good job at doing that (more or less). However I just bought some brass that looks like it's been sitting dirty for quite a while. I'm running ithrough the cob media now and it looks a little better but not great. Will walnut clean it more aggressivly?

Yes, walnut grit will clean more aggressively. Outdoor brass that is chocolate brown needs cleaning with Scotchbrite or steel wool to get shiny brite.

The only corncob media I've used is Lyman's Green media mixed (6) to (1) with their Tufnut media. It cleaned 44 Mag brass I've owned since the 70's that had years of reloads on them but had never been cleaned until I bought a tumbler a couple years ago. They came out super shiny after about 3hrs in fresh media. The dirtier the brass the sooner it takes the media longer to get them shiny.

The plain walnut media I've tried worked well but they didn't come out as shiny, even with some Tufnut added in.

Walnut probably cleans better, but I find it too dusty. I use corncobs with car polish and let the tumbler run as long as needed.

Crushed walnut works great for cleaning. $17 for a 50 pound bag at a feed store. Throw in a couple of cut up used dryer sheets and they will pick up all the dust/soot. At first, they will come out tan colored as they pick up all the walnut dust. Later, they will come out light to dark gray depending on the side of the load as they pick up the soot exclusively. I don't use any additives because they will attract the soot to the media (I've tried that with mineral spirits and NuFinish and it simply makes the media dirty earlier).

Really ugly looking brass cleans up best with a piece of Scotchbrite with the brass spun in a drill with a case holder.

+1 for walnut. Used it for years of really dirty brass. Add a teaspoon of Brasso every other load or so. For me it was more important to get the brass clean than ready for a beauty contest. JMHO

Crushed walnuts at the pet store is cheap. So what if it doesn't last as long? Replace it! Corn cob always stuck in the flash holes for me.

As others have said, a strip of dryer sheet helps cut the dust. Just make sure it has been used in the dryer once. Otherwise, there is a good chance it will leave a residue on your brass.

For handguns I use the cheap Kaytee brand corn cob pet bedding from Wally-World--think it is about $2.80 for an 8# bag. Probably use 2# per tumbling, and discard after about 1,000 cases cleaned, usually 2 batches in my Lyman 1200.

For rifle I use finer walnut media, as the corncob above gets stuck in the rifle cases--something you don't want to find out when you are cleaning .223 Rem.

The used dryer sheets do help considerably, and I also set my tumbler up outside on a nice day to keep the dust outside.

Treated walnut media will. The stuff that has a red color to it, thats polishing rouge and will make them look like new.
I like my brass to look shiney, so I get treated, if you don't then you have to buy something like ISSO case polish to add to the shell to get that like new look.

Consider switching to SS pins with a little dish soap and Lemishine. Cases will look factory new.

A little liquid car wax added to the corn cob shines so bright it hurts your eyes.

Thanks guys. I've ordered some treated walnut and treated corncob from midway. I was almost out of what I had and I needed to get more on my order for the free shipping anyway so this was a good excuse. I have a vibratory cleaner not a tumbler so I can't use the stainless pins.

Try Zoro.com for 20-40 grit corn cob, very fine grit and doesn't get on the flash holes. 29 for 40 lb bag. 5 off on shipping with code "zmail4u". I still got 2/3 of the bag after 2 yrs, or make a group buy and split it into ziplock bags. I use 50-50 walnut and corn. Cheapest place I have found for corn cob, great service and fast shipping.

I have recently used citric acid to clean hulls. Does a good job and is a food product. I actually used some Kool Aid packets in hot water to clean some dirty 40 cal. Citric acid is the main item in kool aid. I just rinsed in cold water and air dried. You can also purchase citric acid at most grocery stores.

For those buying blasting media walnut from stores like Harbor Freight and Northern tool, what grit are you getting?

Wondering if folks have tried some of the other blasting media as well. Hate to buy 50 pound bags to experiment

I just tried some Turtle Wax chrome polish on some really dirty .45 brass some of it was black in my tumbler for about three hours and it came out looking like factory new brass.

I use the fine grit from Harbor freight, it shows 24 grit. Its about the same grit as the corn cob (20-40) i got from zoro.com. Neither one clogs in the flash holes like the coarse will. Goes on sale once in a while and a 20% coupon at harbor freight, haven't used the stuff at Northern tool, but, looks a lot higher priced.
