Treating fired brass is dependent upon what you fired in it. If it's smokeless, I throw it in a coffee can and collect enough to tumble in my vibrator before reloading. Best is to presort by caliber. If the powder was black or a substitute, the brass should be washed in vinegar water before storing to neutralize the fouling. Cleaning supplies, I use MP7 solvent on smokelss and black, but smokeless leads significantly more, so I also have a Lewis Lead Remover. (See Brownells). Hoppes9 is good if you shot jacketed bullets.
