i was driving the other day and i noticed that the inside of my windshield was really nasty, like streaky. i touched it right in the middle to see if it was on the inside or outside and i put a big streak right in my vision. so yesterday i went and cleaned the glass with windex really good, i got in all the corners and everything. then i go to drive today and its all streaky agian. what stuff do you guys use to clean the inside of the windshield?
