Default 703 injector rebuild/clean up

i just got a set of 703 injectors from the wreckers from 95-97 sebring.

even tho the o-rings look great, i want to clean these up and replace the o-rings.

what did you guys use/do to clean these up, or should i just clean them and install, then get a professional fuel injection clean from like canadian tire or wal-mart?

i just finished helping a bud get his GC running after sitting for almost 10 years. We removed each injector, fit a small hose (air hose) about 6" long to the inlet side of the injector complete with the required adapters to connect it to an air compressor (regulated at 20 - 30 psi). In the 6" hose we filled it with Seafoam injector cleaner suggested by the parts guy and then connected the air supply to charge it. With a 12V source, car battery, we then activated the injector allowing the cleaner to pass through and spray into a rag. We only momentarily applied power to the injector repeatedly, almost like its typical function.

This worked for us, among other things we did, it would not start until we had cleaned all the injectors.

I got on ebay and bought injector overhaul kit. Comes with filters, O rings and pintles. I would never put in injectors with out replacing these parts first. I mean they do come from the j/y so better safe than sorry.
