they cant be seen in the sun but when driving and the sun shines straight at the cars windshield you will see it when your driving
i noticed today this morning since it was still dark and i can see it this bothers me and its hard to see the bottom portion of the windows so any cleaners i should use to rid of this? or could this be oil film or something its a new car

2. Twocell Says: Believe it or not.It is human waste.When your breath or sweat,your body emits waste products which builds up over time in enclosed environments.It forms an oily substance mainly on inside of windshield.If it's on the outside,that would be silicone build-up from your windshield wipers.A normal glass cleaner will take care of either.
