That cob is already treated so it should clean/polish as-is. Be aware many polished leave some residue on the brass which could damage/scratch your dies.
Most of us use plain untreated corn cob, and just add a bit of NuFinish car polish to the cob before putting the brass in. It's cheaper than pre-treated corn cob.
Also cut up a used dryer sheet into about 2 x 2 inch squares and put this in with the brass. The dryer sheet will help pick up any dirt and carbon crud, keeping your cob clean longer.

You don't need to add any polish. Heck I've used plain old untreated crushed walnut hulls with no polish and did fine on brass.

As they said ^^^^^
The "green" in your media is a polish treatment, so you don't have to add anything.
When that stuff is gone, you might consider
http://www.drillspot.com/products/521055/econoline_526040g-40_40_lbs_blast_media
It's sold as blasting media, but it's corn cob.
40lb bag for $26.93 and no shipping charge.
And it's ground fine enough not to plug flash holes for those who deprime before tumbling.
