Cleaning brass after tumbling...

I know this has probably been asked 1000 times over....

Cleaning up some .308 brass in preparation for when I can find powder and primers... There is a powdery film on and inside all the cases. I'm using Lyman Tuf Nut media.
Do you clean this off?
What about the residue inside the cases?
What methods do you use?

Thanks for any help!

The inside of the necks gets cleaned when I lube them with a qtip before sizing. I leave the rest of the inside to be turned into carbon when I pull the trigger.

Add a splash of mineral spirits to the media, and drop in a couple of dryer sheets cut into 2 x 2 inch squares to trap all the dust. You will end up with very clean brass.

Simple! Get rid of the tuff-nut media! No kidding, it's junk. The red stuff is rouge, finely ground iron oxide,(rust)! It has a bit of oil mixed with it, that's the film you see.

I wouldn't want an abrasive left inside my cases. Even a mold abrasive like that rouge.

Get this extra fine corncob media from drillspot, shipped free. It's fine enough as to NOT plug flash holes if you elect to tumble after decapping.

If you want a high shine as well as clean film-free brass, a dab of car paint scratch remover added to the corncob works well.

They're going to get their butts kicked over there this election. How come people can't spell and use words correctly?

i second getting rid of that rouge junkyou will end up just flushing through your rifle .if you dont get it out,it made a mes out of a friend's m1 .
just use some walnut shells and go to graf's and get a bottle of there hi luster brass polish it has no ammonia . you will be good to go,if you want to clean any sizing lube off the cases just wash them off with cheap laqure thinner ,you can use a 1 gallon ice cream bucket and a gallon milk jug with a corner cut out of the top leaving the handle .punch some drain hole's in the bottom of the jug ,put the brass in the drain jug ,put the jug in the bucket fill to cover the brass a sture the jug up and down and you wont belive how much jung you will get out ou the inside .save the thinner put back in the casn to use again put a paint strainer in the funnel when you pour it back .
