How do you clean to prevent streaking when rolling windows?

Every time I roll down and roll up my clean driver side window, new dry streaks form.

Does anyone know a good method to clean the part of the door that the window rolls down to?

Sell the BMW and get a Porsche?

In all seriousness, I have NEVER been able to figure this out and I've had 8 BMWs and most of them do it on a regular basis.

I just carry a nice microfiber towel and wipe it off in between washes.

Take a q tip and clean inside the window seal along the door card edge. Dirt is there. That's why it's streaking.
