Most auto manufacturers now only reccomend either a damp cloth or something like Windex on the dashboard because anything that makes it shiny will cause glare on the windscreen and can also cause a film to appear on the inside surface. If anyone smokes in the car that can also cause quite a build-up on the interior glass. In the winter if you run the heat/defrost and get a steamed-up winscreen that would indicate a leaky heater core.
