I use gun cleaner.  Hoppes 9 I think is what it is (I'll verify when I get =
home).

Open the bottle, drop in the injectors, slosh them around gently, and let i=
t sit for 45 minutes or so. =20

They come out sparkly clean :)

Subject: [LML] Injector cleaning

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 jus=
t fine for me.   It does have a short cycle which is OK for frequent inspec=
tions.  The finished product is clean outside and spotless inside.   The la=
st photo shows the troublesome deposits on my injectors.  The shot is looki=
ng 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 i=
njectors were obviously quite dirty and overdue for cleaning.
