This is what I'm using to clean the injectors in the IO550.  So far, it is inexpensive and effective.  The $32 harborfreight ultrasonic cleaner is just fine for me.   It does have a short cycle which is OK for frequent inspections.  The finished product is clean outside and spotless inside.   The last photo shows the troublesome deposits on my injectors.  The shot is looking into the injector from the engine side of the nozzle so that's the area where the jet expands and exits into the intake manifold.  This #2 is still showing some black after an hour of repeated cycles in the bath.   These injectors were obviously quite dirty and overdue for cleaning.
