Better safe then sorry.
It can cause pitting, but most likely wont.. the carb cleaner is more harsh on the sensors around the TB because it is formulated to remove heavy varnishes found in carburetors. so that means it should be 100% okay to sue on the IAC since it is a valve. dozens of people have used carb cleaner on it it just is stronger than the Throttle body cleaner
