I tried cleaning this window this past weekend - I wasnt very successful. I pretty much cleaned the top half pretty good. The bottom half is another story. I think driving with the windows down really dirtys the inside of your windows pretty good over time. Does anyone know an easier way to clean this back window? Its almost like you have to be a contortionist to be able to clean it well. My body doesnt want to bend the way it has to get the job done right. Does anyone know of a better way ?
