A friend of my wife's competes in Western style competitions where she shoots lever guns and revolvers from horseback. She uses black powder loads and can do basic cleaning, but at least once a year she has been sending her guns away to someone who can do a complete strip and deep cleaning and make minor repairs. Is there anyone in the PDX area that she could go to for this type of service? Maybe ultrasonic? She's tired of having to ship her guns off.
