After taking a few years off I will be getting back into reloading this winter. I've read about adding a spoonful or two of some kind of polish to the media when tumbling brass but I can't remember what kind of polish it was. Anybody know?

Something like this, I reckon: http://www.midwayusa.com/eproductpage.e ... t=11082005

I think that it was a household polish. I didn't want to have to order anything.

Household polishes contain ammonia, which does bad things to brass.

Andrew is correct,I'd go to gunstop, I'm sure he stocks something,or else try Cabellas.

try just washing the brass first. I use one of the media separators and a 5 gallon bucket of hot soapy water. You can use any net or pourous bag as an option. Just get the brass in there and agitate it around for a while, then let it sit for 15 minutes and agitate again and drain and rinse. dry over night and then run thru the tumbler, the stuff gets new brass bright.

I use dawn dish soap seems to work wonders.

I use Lyman Turbo Charger. I think Flitz also make a media additive. I am going to try that next.

I add cerrium oxide to the media in my tumbler. Works great.

(think el'cheapo turtle wax brand liquid rubbing compound)
