Unloading brass tumbler tank

After running a rotation cycle which cleans your brass very effectively it's very important to thoroughly rinse the brass and stainless pins till the water remains very clear. All impurities and waste products will be rinsed away leaving brass looking like new, stainless pins clean and the tank clean ready for the next batch to be cleaned.
I will repeat a previous comment regarding the use of disposable gloves. It's best practise to get into the habit of doing so the same way you would do when casting bullets from lead and even while loading ammo on your reloading press.
It's surprising how many and varied the toxic substances exist in the reloading, bullet casting and most other aspects of firearms use. Gloves like these are a small price to pay to keep oneself as healthy as possible. It is unlikely you will wash gloveless hands effectively enough to clear all remnants of these toxic components after working on the reloading process for hours on end. Something we all tend to do in preparation for the next range outing.
