I've cleaned my injectors, however the engine is not one that I care to fix, I just like hearing it roar, so I'm not sure what this will do in the long run to your injectors.
What I did was I put a wire wheel on a drill press. locked the position, and wire wheeled any deposits off the metal part of the injectors (just for handling sake... dirty stuff sucks). Don't do this on the connector or the end of the injector, as they are plastic based materials.
I then used a car battery to quickly power the injector and click it on and off. At this point I could tell which injector was bunk... But after a couple of clicks, it worked better.
I then filled a stainless steel container with varsol, and left the injectors and o-rings in the varsol. I filled it part way up so that the tips of the injectors were positioned downward. 2 days later, I opened up the container, and battery tested the injectors and they all clicked louder than before, signifying that they were freed up to an extent. Looking in the varsol, I saw clumps of dirt and crud floating around. Thus, the conclusion that it did draw something out of the injectors.
Put them all on, and started it up..... still a wonky idle...toiling over what's wrong... I realized that this time around, I left the 6th spark plug wire disconnected... Once reconnected, it ran great, all the way to 7000.
