Brass tumbler additives?

[Dale Gribble]

Do the primer pockets come out pretty clean after ultrasonic? I’m with Mapper about not having to dry, but I also don’t like cleaning the primer pockets. I also wouldn’t want to dry tumble after ultra sonic. If they come out of the ultra sonic cleaner with pretty clean primer pockets, that may be the best way to go and just let them air dry for a few days.

I use a HF ultrasonic and it gets the brass and pockets clean. Not clean like thumbing with steel pins, but the dirt is gone, its just not super shiny brass. I use it for small batches of rifle stuff.
