How do you "clean" your dies? I stuff a rifle or shotgun bore mop in my cordless drill and soak it in paint thinner, and ream it out. follow that up with a rag and light oil.

I tumble clean then resize so no grit gets inside my sizer die then tumble clean again to get the lubricant off the cases.

I use brake or electric panel spray, and then blow dry with forced air. Very simple. Tom.
