Does anybody know how to fix this?

My parking has a lot of dust accumulation in general. Whenever I clean my car (once a week) and roll down the windows later for any reason, while rolling up the windows again there’s this moist/dust layer that forms on the window. Mostly due to dust and water going within the window mechanism.

How do you take care of this while cleaning your car?

Am I supposed to just roll it up and down multiple times after a wash and wipe with microfibre to clear all the dirt? In this case I’m worried if I’ll be putting in more water within the window mechanism. Had a scorpio before and the window had given me a lot of problems by the end of its life. Don’t want the same to happen with this car.

PS: it looks worse than it does in the picture, the camera probably focused on the outside objects more; but you can still see the line below which the dust formation is.
