Just fill your RBCS or Dillon media separator with water and spin the brass submerged in the water. This method removes 99.999% of the pins and helps to rinse the brass. I normally dump and refill with clean water 3 or 4 times and I'm good to go. Fully rinsed and all the pins are out of the cases, even smaller cases like .17's. In warmer weather I just put the garden hose in the separator and let it run while I spin the brass.
