Tumbler or Sonic Cleaner

the dust from the corn cob

I've been using this stuff for decades and don't understand what you guys are on about here. I've never had dust issues at all, there's a minor residue when removing cases from corncob but no suspended particulate. I always have the lid on the tumbler and clean it regularly. The cases get toweled after and the towel washed. Yes, it makes sense that there's lead azide in the corncob from the primers. That's where it would go. We make too much of nothing.
