Tina,
I am a clean freak also... But since there is no way (that I can think of) to really filter out the air, I guess I will just have to resort to soap and water

. I figure either way you vent your engine compartment, it will eventually get some dirt in there. We just have to stick to washing it with the rest of the car...
