Hey folks, anyone figure out how to clean the top part of the sunshade (the side seen from outside the car)? I've accumulated some tree debris, etc and since you can't close the shade when the moonroof is open I can't get in there to clean it out (too little space for even one of those crevice tools on vacuums). I use the tilt function to vent the car on hot days, and one or two unexpected rain showers have also spotted the sunshade from dried water drops, any thoughts ther too?
