Fuel injector cleaning for Honda S2000

I've got a few questions for y'all regarding fuel injector cleaning for the Honda S2000.

How exactly do you clean fuel injectors on our cars? Do you even need to clean them if you use [insert your brand here] 93 octane gas? I specify 93 octane because I am led to believe that there are additives in this grade of gas which may or may not be present in lower grades (e.g. 91 or 89).

philiam calls fuel injector cleaners "snake oil" (i.e. useless [see here:]), and Woodwork says just not to use them (see here: However, repiv says that fuel injector cleaners are one—well two—of four viable options (see here:

So who's right? Can I use the bottle stuff or is my only recourse to pull the injectors and give them to my dealership for cleaning? Am I definitely not going to be able to do the latter on my own with a relatively small investment of time or money? I don't see any DIYs for this process on here, S2KI, S2KCA, Honda-Tech, or any of the other boards I frequent. I suspect someone knowledgeable will chime in with "don't worry about it", but I figure this post could serve to clear up some of the obfuscation regarding this subject. Google certainly ain't helping me much on this one. Thanks.

Currently have no reason to clean them...runs fine. I have in the past used SeaFoam on many of my cars, with very good results. One of the really fun things about these forums...everyone gets to air their feelings on fluids, tires, bolt ons... that is why you see so many different posts. When it comes right down to's your car, do with it what you want. I doubt that any of the additives would harm your car or least for that tank of gas.

Sending them out for service is the only "right" way.

Just the additives in gas (Chevron with Techron). Owner's manual states not necessary to use any type of extra additive, that the additives in name brand gas is enough.

unmount the babies. Put them into an ultrasonic bath filled up with isopropanol.
That's the way garages used to do before they decided to replace them when dirty...
