I stumbled onto this a couple years back by mistake but it finally serves a purpose. Ive been painting my brass tubes when casting and glueing up acrylics, but have had a few problems with paint rubbing off when inserting into the drilled hole and leaving brass shine in the blank. I remembered back when I was trying to clean out a piece of brass that had gotten cloggeds, with some liquid drano. The result was dark brass. I just finished a bucket of tubes and thought i would post the before and after. I sand and rough up the tubes first and then stand them up on end in the bottom of a small bucket. I pour in liquid drano just over the top of the tubes and let sit over night. The next day I rinse and dry and they're ready to go. One thing, drano will bubble up and out of the bucket if its not very tall, so put down a drop cloth.
