I did a search, but I guess my search criteria sucks or something.

So how much do you use for ~7lbs of corncob? (Lyman 2500 tumbler)

Thank you. Figured I'd ask, I usually overdo minor things like that!

I've read of people trying it and figured I'd give it a try. I'm tumbling dirty range brass and my media is about dead so I'll give it a shot.

Mineral spirits keeps the dust down.

It will renew your media indefinitely if you use it every time. I'm still using walnut media I bought over 15 yrs ago. Really cuts lube off cases and brass comes out shiny. I never use polish anymore.

I've been using some kind of liquid polishing compound for fiberglass boat hulls. It also reduced the dust to zero and polishes my case twice as fast and I also haven't changed my media for about 15yrs.

I throw in used dryer sheets also to help collect the fines buy don't get many anymore.

Thanks, I didn't know if the mineral spirits was a new mouse trap or what it was.

That worked great!
Granted, my media was old and it was taking quite a while to see results. But after adding a splash of paint thinner my cases were shiny as can be in about 2 hours(was taking longer) . I'm done with the polish for now, I have a gallon of this stuff.

Old school stuff still rocks. Don't let the common core progressive hand wringers stop you from learning the ways of the ones who came before.

I was thinking that a 1/2 gallon bottle of Beefeaters was going to help me put up with the whole polishing situation in a nutshell. That's the kind of spirits I would try.:D Recommend a glass full--on the rocks.

Put about 1 tablespoon of Nu-Finish car wax in the media, mix up good, best shine you'll ever need.

Well, you gotta walk it through a room with a bottle of vermouth on the wall, than point it in the general direction of a jar of olives. The perfect martini after loading chores.

I you add to much it won't hurt anything, just give it awhile to evaporate

You want to use mineral spirits to thin out a polish like Nu Finsih. MS by itself is not going to do much.

If you want to hold down dust use a few drops of Mineral Oil (Ballistol or pure Mineral oil from the drug store.

I have a related question, people use nufinish in the media too, but I can't tell if it's nufinish polymer WAX, or a car POLISH. When I think nufinish, I think of the wax (but it's not wax) not a polish which would have a fine cutting Agent, but in my mind a tumbling process would probably benefit from a polish, not a wax. Which is it?

I use Nufinish, "The Once a Year Car Polish".

Obviously people have been doing this with good results so this is probably a silly question but do any of you guys who use mineral spirits in your media worry about the oil residue destroying primers?

mtrmn

If you just use mineral spirits without all that other stuff I see on here then there will be no oily residue. What tiny amount of dampness may remain will evaporate immediately. In 30 yrs I can't remember ever having a primer that wouldn't detonate.

JUST mineral spirits alone is what I use in my media, no polish, no wax, no oil etc etc. My brass comes out very shiny if I leave it in there several hours. Myself, I don't care if it's shiny as long as it's CLEAN. I tumble once with walnut and MS to clean the brass, then after sizing rifle brass I tumble it again in fine ground corn cob and MS to remove lube. Then I make sure the flash holes are clear and load them up. KISS principle.

Splash of mineral spirits and Brasso...A little dab will do ya.

Before my brass goes in the tumbler, I soak in hot water, vinegar and Dawn for half an hour or so. I rinse the brass in clean hot water and dry in the sun. At this point, the brass is clean enough to reload. Most run it though the tumbler for a couple of hours to make it pretty.

The lead salts that everyone is so afraid of, goes down the drain. If you tumble dirty brass, you could contaminate the area around the tumbler with airborne lead salts.

Don't use Brasso ! It has ammonia in it, will breakdown the brass structure of the metal. YMMV

Try replacing that vinegar for citric acid. Cleans better and doesn't tarnish the brass that much.

I do this because all the brass I get is range pick up, and it's usually dirty with mud or sand. If I'm loading for a match, I decap after the wash and run then through a sonic cleaner so as to get the primer pockets clean.

I haven't tried mineral spirits yet. So far I've been using a metal cleaning solution with good results, but I'll give them a try.

Nordeste,

1. I am cheap. A couple of tablespoons of white vinegar is pennies. The equivalent amount of citric acid is dimes.

2. You are correct about a slight amount of patina that the vinegar may sometimes leave behind. This always goes away in the tumbler with lizard litter, mineral spirits/car polish, and a dryer sheet.

If I were not going to tumble, the citric acid would be a better solution.

Search youtube for the video of noted pistol shooter Jerry Miculec using a concrete mixer for a tumbler.

Thanks for the thread guys. It's always good picking up nifty little tips like this from the guys who went before.

Well, there's not much to say. You're right that vinegar is cheaper, but the other day I got a kilo of citric acid (that's over two pounds) for less than 8, and I'm sure that'll do for a couple of years.

Thanks for the link, though ;)

question if I may?
mineral spirits renews media indefinitely.When do you consider your media done/dead?
The last I had and finally tossed after it's 3rd season( I was only loading for hunting past 2 yrs) was doing it's job but the dust was unbearable. For a while tossed a rag over the top of the Lyman to keep it down. Even with Nu-Finish there was still a bit of dust. Noticed the fresh stuff was a bit bigger. ;)

You will notice it takes longer to clean / polish your brass. Try a few dryer sheets every time you tumble and after a few go arounds you will start to see less dirty dryer sheets. Also, try putting in a splash of mineral spriits to help the cleaning process

Glad it works for ya- thats why I like it, anyway :D


If dust buildup ever bothers ya, you can run the tumbler, cover off, for a few hours somewhere away from anything that matters, and it'll get most of the dust out.

I add 2 caps full of Odorless Mineral Spirits before tumbling with a cut up dryer sheet. It's been my recipe for years. :)

Don't know about gahunter, but I use mineral spirits EVERY time.

Bob4-I'm still using some corn cob media that came with my old small Midway tumbler that came packed in a 5 gallon bucket. That was bought in the late 80's. I use it for the tumble after sizing to clean off lube. Again, using min spirits every time.

I've never tried it. And I got rid of a 50 lb bag of walnut shell because of the dust. Are you saying the mineral spirits will fix the walnut dust issue?

How hard is it to believe that mineral spirits will cure cancer and cause you to live happily everafter when used to tumble brass? :D

medalguy
April 9, 2014, 12:54 AM
I'm not sure about curing cancer, but the happily ever after part..........

I use 2 glugs out of a gallon can for my tumbler which is a cement mixer. The MS really softens and cuts carbon off the brass, and the dryer sheets remove the dirt and carbon. I have one batch of cob I use for initial cleaning.

I use another batch of cleaner cob with Nufinish if I want to polish the brass. Still add MS to the mix.

I'm only about six months into reloading but I tried the mineral spirits add in three tumbler loads ago and have been pleased with less tumbler time and no dust. Just one of a ka-zillion ways to clean brass, but like many others, it works.

If you put to much mineral spirits in the media don't worry as it will evaporate out a short time later. I started using it 15 years ago with walnut media and would never give it up.

+1. A couple tablespoons? A couple capfuls?

The OP states his tumbler holds 7 lbs of corncob. I think I'd be a little less stingy.

Also, plain WATER will get your cases cleaner. I put my brass in the tumbler, wet. It takes about 40 minutes to dry with the lid off, which is fine. That's about how long it takes to clean. No more 3 hour, 6 hour, or even overnight tumbling sessions for me. It makes a big difference. The corncob won't be bone dry for several more hours, probably not until the next day. But that's fine. The trapped moisture also helps cut down on the dust. If I run multiple loads, I make sure to strain the subsequent batches of cases better before putting them in.

Right! I just kinda splash it in there with it running until I see some small clumps rolling around. I'd say around 2-3 oz. That usually does it.
