I cannot take credit for this one. I have seen it in several places and do not know who originated the idea, but when I tried it, I have been amazed at the way it works so well.
Case cleaning for me has evolved into a two stage process. First, a vibrating tumbler with walnut media for the first, rough clean. Next, a rotating tumbler with corn cob media spiked with Dillon Rapid Polish 290, to really sparkle the brass.
PROBLEM: The cleaning media and the resultant residue means the media gradually becomes a mix of the media plus fine, silt-like hazardous dust. Primer residue like lead stiphinate and other
harmful stuff. Eventually, this dust begins to inhibit the media’s cleaning and polishing capabilities. That is when you change it out and technically, this is most likely a hazardous waste.
SOLUTION: Bounce Scented Fabric Softener. No Kidding. The first few times cut a single softener sheet into four pieces and throw into the tumbler with the cases. Clean as usual and remove the softener sheets and carefully discard. After a few times, you only need two cuts (half sheet). This one is incredible. All the hazardous dust collects on the sheets, the media looks like new and just keeps on going like the ever-ready bunny. No fine poison dust to worry about breathing or handling. Big Grin ==> And your cases smell really good and no static cling to the powder you add.
Just try it before you point at me to tell others I am a nut case.
