I use both a wet rotary tumbler and a dry vibratory tub. I use the media from Arizona Sharpshooters in the Thumbler Tumbler and dry untreated walnut hulls in the vibrator. Now keep in mind I mostly shoot black powder but it will clean any and all cases. The walnut hulls will not give you quite as shiny of brass as the corn cob media will but it does make for a nice clean looking case none the less and creates a little less dust.
With the wet tumbling, I think your water makes  a difference on how well the detergent you add works.  You may have to experiment some to find what works best for you.

Loaded cartridges or fired brass.  If loaded wipe them down by hand. Don't think I would trust any kind of tumbler or vibrator & live primed cartridges

I use a rotary tumbler with ceramic media and water with some laundry soap in it. Or dishwashing soap. Both work well for me.

I seldom clean brass but when I do I use a tapered mandrel spinning in my drill press. Slip the case onto the mandrel holding it up with a piece of fine steel wool. Brasso or something similar on a small rag is run up and down the spinning case. For really bad cases (the kind I quit scrounging) steel wool and Brasso works well.

I bought a stainless steel pin tumbler and I use it exclusively now.  I've never had brass that looked this good in any of my old style tumblers.  Even filthy range brass or brass that has been loaded with black powder comes out spotlessly clean inside and out.  If you take the time to deprime your cases first before tumbling them the primer pockets will be squeaky clean too.  I use slightly more than a gallon of tap water, a squirt of Dawn dish washing soap, and about 1 teaspoon of Lemishine and then tumble my brass with the stainless steel pins.  After they are cleaned I rinse them thoroughly with some fresh water and then put them into a food dehydrator overnight to dry them completely.  I only use my old vibrating tumbler for powder coating cast lead bullets now.

John Boy,

I see the HTML link conversion in you post did not pick up the full address for the Strat-0-Sheen powder.  Let's see if this works:

I converted it to a shorter link using (You need to Login or Register to view media files and links)

Also, can you make an educated guess on how much of the 3mm triangular media would be adequate in a 15lb capacity Thumler's tumbler?  BTW, is the triangular media size 3mm x 3mm or 3mm x 5mm?

Thanks.
Wayne

Wayne- try this link for Strat-O-Sheen (at the bottom of their NEW website) ... (You need to Login or Register to view media files and links)

For a 15# tumbler, order 3 lbs of the K-Polish and you will have plenty.  I ordered 5# for the Lotrone two 6# drums and have plenty left over

The K-Polish triangles are 3mm x 3mm

I am pretty sure it does.  Kind of smells like it, I have not used that stuff in years.

Unless you plan on soaking the brass in Brasso overnight, which no one would do, them it won't hurt the brass.  Ammonia will dissolve copper and zinc in brass but it's not at all a problem if Brasso is used to polish with a rag.    I find the polish residue hard to remove so I use other polishes.
