I use a combination of corn cob and Lizard Litter from Petsmart with a tbl of liquid car polish and a couple used dryer sheets thrown in to collect the dust.
Never read of anyone using saw dust. The other media cost very little and last a long, long time.

I'm of the opion that washing my brass and then sizing won't hurt my dies, others will argue with this claiming that dirt will scratch and harm carbide dies. In my experience it doesn't but use your own judgement.
Regarding using sawdust for media, don't know never tried it. I suggest you go to an Industrial supply house like Graingers and buy ground corn cob, its only about $23.00 for a 40 lb. bag and you get alot. I use the 20/40 grit as this does not stick in the flash holes. Add a very small amount of car polish like Nu-Finish or any other polish to the media, about a cap full to a quart of polish.
Alternative is to use bulk rice from the grocery but it will get stuck in the flash holes.
Hope this helps

Years ago (before a lot of people on this board were born) I tried everything imaginable as tumbling media. I tried rice, strips of rags, sawdust, powdered Borax (don't try this one) and just about anything else I could get in the tumbler. The best of all of them is corn cob, with ground walnut shells next.
Sawdust will clean, but not really polish. It also leaves a lot of dust on the brass.
I currently buy a 40 pound bag of ground corn cob for $15.49 and add Berry's Brass Polish to it. I also use one tumbler (I have three tumblers) with plain corn cob to remove any polish residue when sizing in carbide dies, which does away with the fine scratching you get from the ultra fine grit of the polish. It doesn't matter what brand of brass polish you use, since they all act the same.
I've tried the car polish route, but it wasn't as satisfactory as the products made specifically for polishing brass cartridge cases. No matter what you use, avoid any polishes that contain ammonia, since it attacks the metal and will make it brittle. I've seen this happen and it ruins the brass.
Hope this helps.
