Hi all, I did an oil change yesterday and when replacing the oil filter I noticed there's a lot of salt left over from the winter (I live in NJ) in the same area. When I wash my car I spray water up and under the car, but the aero-shield blocks it (obviously) and salt is left. Is there anything in there I can damage by undoing the aero-shield and spraying a bunch of water up there to get rid of all the salt? I'm a bit afraid as there is a metal box with two sensors plugged into it. No idea what it is but it's edges are starting to rust!
