I tried to wash my car as much as I have time for. I keep up with cleaning my engine. I most likely wax my car too much, but I am terrible at cleaning my front window inside. I just think it is hard to not streak it. Now I never see the streaks till I drive into the sunshine in the early morning or late night, but streaks are there. I use just amonia and water (warm) but I just can't seem to get the right angle at cleaning the inside. The angle is tight and I try to go up and down from dash to top. Is there something you could suggest to me that would make it easier to wash the inside of my front window? A tool, or something? Am I the only one to do this? The rest of the inside windows are easy and clean up nicely. The outside is a pieace of cake. I have a roadster so keepeing the top down alt the indie front window gets a little dusty.
