Funny question. Some will say yes, others will say no because carb cleaner can damage the sensors.
FWIW, I just cleaned mine, on the jeep, with carb cleaner. Right, wrong, or indifferent its what I did and I have nothing bad to show for it.
yup, and of course into the little hole where the IAC sits. Grab an ol toothbrush to scrub at it after you hit it with the cleaner. Do it with the jeep running and don't get button pressing happy or it'll die on ya. Not that that will hurt anything, you'll just have to walk around and restart it.
Yep carb cleaner is fine and it is always best to entirely remove the IAC for cleaning. Be sure to clean the TB's orifice the IAC's plunger fits into as well. Make sure any cleaner you use says Sensor Safe on it as well to protect the 02 sensors.

Some TBs have a teflon coating to prevent build up (I know Ford does). Carb cleaners may damage the coating while TB claners are not supposed to.
teflon is resistant to almost every chemical. Its one of the most resistant materials that there is.

you must me really lucky! IAC failure is probably one of the most common failures on all vehicles. The inner guts get worn out and cleaning only buys you some time. I be surprised if a cleaned IAC lasts more than a year before it acts up again. I've probably had 30 customers that cleaned their mustang IAC to save some time and had issues months later that were resolved with a new IAC. I guess the business I'm in I deal with a lot more failed parts than most people.

A few years back when I had the 5.2L ZJ, the info on some of the ZJ forums said that DOT 3 brake fluid was Chrysler's recommended cleaning agent for the IAC sensor. Works great on the sensor, never had it "fail"; cleaned twice in 140K miles to correct the idle surging. I cleaned the orifice and TB with TB cleaner
