Idle control valve

Hello everybody,

I know that he idle control valve is a reccurent topic. I did a search but did not find the right answer.

So my question is for an 1989 300 CE 6cyl.
I would like to know if the ICV is cleanable and how to do it.
Or perhaps it's better to have a new one ?

Thanks in advance for your answers, and be lenient because english is not my mother langage.

Best regards
