I clean and dust my dash all the time, but I have noticed black specs on the dash and the dash was sticky. Finally got a chance to really clean it today. Used 3M General Purpose Adhesive Remover and all i can say about this stuff is, WOW. It took it all off with a little bit of effort. :woot: Here is a pic of the towel after I was done. It was almost like tar. :dunno: Bought the truck used and it has been there since purchased.
