Cleaning/Replacing an IAT

Hey everybody, I'm going to be working on my civic next week to try to get this whole no start problem sorted. I know the gammy IAT wont cause a no start/spark but I want to get the ECL sorted just to rule it out for definite.
My question is, whats the best way to clean an IAT? mine is on the back of the IM (D15B7), the screws holding it in look as if they cant be loosened? It looks like the screws have no indent for a screwdriver? they look more like rivets... maybe they're full of crap but is that normal? Once its off how best to clean it, or shall I just buy another one?
