So I am getting a stubborn white film that has built up on the inside of my windows. I have a new 2011 SE with 1200 miles. I have been told that this is typical of new cars and it's a mixture of powders and plastics from the manufacturing process that will eventually go away. In the meantime, I am having to seriously work the windex on a weekly basis. Even with windex and elbow grease I am still having streaks. Anyone else experince this? Anyone have any ideas of a good cleaning process?
