RE: Cleaning Brass
I deprime and resize, use the RCBS liquid in my wet tumbler, rinse, shake out, set on tray in oven at 140 for about 15 minutes. Very easy and does a great job. Used to use cobs, tooo much mess and time, and didn't do near as nice of a job. I'm sure any liguid brass cleaner probably uses the same major ingredient. Tumbler is the RCBS Sidewinder.
