An article in performance engineering recommends 1,1,1 
trichloroethane and a stiff bristle brush to clean the outside.  
Don't immerse the injector, just scrub at it.

An ultrasonic pen or jewelry cleaner and fuel injector cleaner 
(Chevron Techron) to clean the outlet.  Stand the injector up in the 
cleaner so the outlet is in the solution and run the cleaner to 10 
minutes.

Run a half n half mixture of mineral spirits and injector cleaner 
thru the injector on the bench to clean the inside.
