I bought 5 lbs of this media. I already had a standard (Not the new high speed) Thumler Tumbler that I tried to use with walnut media a couple of years ago. (That was too messy for what I got in cleaning).
I Add:
1. 1 TBL SP of this LemiShine (my local target carries it).
2. 2 TBL SP of AJAX dishwashing liquid (raided from my wifes kitchen).
3. I Add my deprimed brass to be cleaned. (this really cleans primer pockets so don't bother to run brass with the old primers in it)
4. I put the drum on the bathroom scale and add water to NOT MORE than 15 pounds of total weight and bolt the top down. (this step is because early on, I added the recommended "Gallon" of water and the drum bogged the motor down. When I weighed that drum it was at 22+ pounds. My tumbler is rated for 15 pounds)

With my standard speed tumbler, I run the brew for between 3 and 4 hours. (Never needed more than 4 hours)

CLEAN BRASS INSIDE and OUT. CLEAN PRIMER POCKETS. SHINEY BRASS. 30-06., 6 BR, .223, 260 REM. 45-70.... All Clean.

Thanks rc
