Use the PCV intake hose or just crack the joint between the intake hose and the TB. Failing that, try one of the smaller vacuum lines, and continue to just spray copious amounts of stuff down it's throat with the engine off (use a rag to catch the overflow). You'll see the brown gook it's washing out of the intake.
The above methods don't clean the injectors; similarly, fuel additives don't get the TB, EGR, or, most importantly, the IAC.
