I've done it twice. I used engine brushes, Chemtool B12, carb cleaner and a shop vac. Process is simple once the intake manifold is removed, soak the closed valves in B12 wait 20-45 minutes then go to town with the engine brushes once finished suck up dirty residue with shop vac. Once that's finished spray the closed valves with carb cleaner then again go to town with the drill then suck up the residue when you are finished. This process will need to be repeated a few times (till the valves are clean). Once those valves are clean rotate the crank and work on the other valves. In my experience you should have 4-6 valves closed at once. Be sure to suck up all the residue with the shop vac you don't want any lingering particles when you are done.
Here are is my before and after at 40K miles. Didn't notice much of a power difference just better idle and throttle response but my valves weren't that bad. I'm sure if they were worse it would have impacted performance a lot more.
edit
I use the engine brushes with a drill.
eh
It cleans shit out and burns varnish and all that.
Seafoam these days is more of a fuel stabilizer (slightly) and a valve lube. as well as burns carbon :P
b12 burns crap out of passages.
seafoam es smokeh.
yes you put it in the gas.
I use seafoam when I buy a new vehicle to lube the valves as well as I like smoke :P
be careful how you mix. sometimes they don't play nice with cat converters
Depends on what you're trying to do with it. People seem to want to use fuel treatments as a cure-all, in which case they are ALL worthless. You can't pour some stuff in your fuel tank and expect your car to magically run like new.
If you have dirty/clogged injectors on a car, in-tank cleaner still doesn't do too great a job. For cases like that, I prefer using a cleaner that is run directly through the fuel rail, which is a different cleaner altogether and requires some special equipment to use. But if you want to try an in-tank cleaner first, then yes the professional-level stuff is much more potent.
If you can't get your hands on pro-level cleaner, the next best thing is Berryman's B12 chemtool. I've used it on several occasions and it's way better than seafoam or any of the other garbage that parts store guys try to sell to everyone that walks in the door. Oreilly's sells it, not sure about autozone or advanced.

Careful with that stuff, though. It's VERY flammable and the fumes are quite hazardous.
