I have successfully cleaned my injectors by first removing all oils outside and inside the injector by dipping them in clean acetone twice. Then I soak them over night in a light acetic solution of vinegar or carbonated water, which is carbonic acid. Then I dry them in denatured alcohol, then scrape the remaining carbon off the injectors with razor blade, dental pick and wire brush, then soak in WD-40 until needed.
I now have three sets of used injectors that I have prepared in the above manor. I pull them from wrecks at junkyards for $88/set. I have two sets of injectors soaking in WD-40 for 2 months now.
Here is a pic of a coked injector:
