Some just get hard of hearing. It may not be age related.


The year is important because some model years spent time stored on parking lots. Limestone Gravel parking lots put layers of lime dust on the windshields and morning dew turned it to carbonic acid.... etching the glass. Short of polishing compound, there is little that can be done.


Strong pressure with cleaning fluids may stress the windscreen glass and cause a stress fracture. It is how mine broke spontaneously the day after I carefully polished the haze. This after a glass guy explained to me how lime dust etches window glass. A little research had previously told me my 2006 model was stored in SC for a year on a gravel lot.
