Cleaning a 'film' off glass

The inside of my windscreen (BMW330i/2004) is covered with a film that I can only assume comes from the a/c - it's similar to the haze on a smoker's windscreen but more resilient to attack by cleaners (which just smear) and vinegar.

Any suggestions for getting it off and for anything I can do to stop it happening, apart from turning off the a/c of course?
