I use equal parts Simple Green and water in a heated ultrasonic cleaner. Blow the parts as dry as you can with an air hose, spray down with WD40, let drain on some paper towels over night and do a final wipe down and a very sparing application of synthetic grease on the bearing surfaces. Good as new . . . .

I use Lyman Turbo Sonic Gun Parts Cleaning solution and distilled water in an ultrasonic cleaner. Works for me.
