Hey guys, I did a lot of research on cleaning brass and what I came up with was getting a 3 lb tumbler from Harbor Freight, stainless steel pins and some powdered citric acid. I put about 1 3/4 pounds pins 100 cases of either 40 or 9, deprimed, 1 tsp of powder 1 squirt or dawn and just cover the brass with hot water. Seal it up and let it turn for about an hour. The brass came out just as clean as new, even the primer pockets. Total investment just over $50.00 and the pins never wear out. 2 1/2 pounds were $20.00 the tumbler $32.00 with coupon. $3.00 per pound of citric acid and dish soap. I am totally impressed. I can't clean a lot at one time but I custom build all of my bullets so slow is fast. If I can figure out how to get a photo I will. Also there is a double barrel tumbler for just a little more. I wound recommend this to anyone who is reloading for fun.
