Cleaning IAC valve

[scoobydrvr]

When I was going through the motor, I took the idle air control valve (IAC) off and thought I had it cleaned up pretty well. Unfortunately, now that I've been driving it for awhile I've started to notice signs that I didn't get it cleaned adequately, I think. Perhaps I have higher expectations for a 17 year-old car than I should but it seems like it shouldn't be going *crank-crank-crank* brrrrup, brup, baaaaaahhh... when I start it. Of course, it only seems to do that when the motor is cold, which makes me think it's the IAC.
Anyhow, all that to say: does this sound like a sticky IAC problem and is there a better way to clean it than drowning it in brake cleaner and exercising it?
