You need to take it out and soak it in fuel or Carb Cleaner. It's not the bit you can see
when you take it out that needs cleaning, it's the hidden airways that run round between
the valve area and the valve casing that feed the air to the second half of the valve.
It's these that clog up with oil.

There's no point in cleaning this valve unless you've checked and cleared the Jet just
below the throttle body that the small breather pipe is connected to. It's the blocking
of this Jet that causes the oil mist to flow through the IACV and block it.

If it's blocked, your clean valve will start to oil up again the next time you start your
engine.
