Simply remove the o-rings and soak the parts in 75%+ isopropyl alcohol for at least 4 hours in a separate container. Then use your favorite cleaner in the ultrasonic tank to get things back to clean as new. Be sure to remove the rubber o-rings before cleaning and wipe with isopropyl alcohol wipes after cleaning.
