Clean your injectors
I've removed and replaced injectors without replacing the o-rings. Be careful you don't cut them when you re-install though (I used silicone grease). The procedure is, re-install on the fuel rail and plug them all into the manifold simultaneously.
I'm damn skeptical. You're cleaning off the goo from the outside of the injectors but, not really anything in the internal mechanism. Even professional injector cleaners clean the insides. I'd think you be better off running a real injector cleaner through the things, something like BG44K.

Well I had an injector "missing" at idle and I ran numerous bottles of Techron thru the system with no change. After removing the injectors and cleaning them it idled like a a V-8. No more miss.
As to the o-rings, cushions and manifold seals I would recommend replacing them at the time you pull the injectors, it's cheap insurance and the miss may be caused or aggrevated by a leaking seal at the maifold or o-ring at the fuel rail.
BTW the factory manual calls for engine oil to lubricate the seals and o-rings, not silicone grease.

If you clean them, remember to replace the o-rings, cushions and seals. It's abut 38.00 in parts from the dealer.
If it worked for you then that's great. I remain skeptical that you could actually get into the inner workings and clean the goo out that way.
The only injector cleaner I ever used that seemed to work was BG44K, So, that this other stuff didn't work doesn't surprise me. There are commercial companies that do injector cleaning too (I believe it's RC). They take the injectors clean them and flow and pattern test them to make sure they spray properly.
I agree that replacing the o-rings and injector seat seals is the right way to do it. I would have too if I had the parts handy. My experience is, I didn't get a leak but, that doesn't mean someone else wouldn't get one.
