I use a Frankford Arsenal tumbler for cleaning brass in large quantities. The recipe calls for water, a squirt of Dawn dish detergent and a dash of Lemi-Shine. Now, I typically buy my Lemi-shine from our local Canadian Tire in High River. However, the last time that I was there to purchase some, none of it was on the shelf. The computer help desk stated that the "product was no longer available". I freaked a little bit, thinking perhaps that it was discontinued and wondered about an alternative. Turns out, I didn't have to freak out, Walmart and Amazon.ca still have it...pheeewww, that was a close call. Nothing cleans brass like stainless steel pins, Dawn and Lemi-shine.
