Like most of us I cleaned my brass with corncob/walnut media for years, when stainless steel pins came along I gave them a try. I was satisfied with the results from both but never liked the job of separating the brass from the media. Walnut or corncob got stuck in the flash hole and the pins would wedge themselves in the primer pocket, both situations called for laborious sorting. Since I was already adding Dawn and Lemi-shine to the pins I thought why not eliminate the pins and see how the brass looks. To my surprise after three hours of tumbling in Dawn, Lemi-shine and hot water the brass came out spotlessly clean. Best part no media in flash holes or pins in primer pockets to mess with, so I no longer use media or pins and have nice clean shiney brass.
