I've had a problem in the past that my water pump in the motor compartment was leaking. The problem was repaired under warranty, everything seems to be OK, coolant levels remain stable.
From about the same time I had some problems with a thin grease-like film deposit on the inside of my windscreen (caused by the anti freeze compound in the coolant fluid?).
I tried a number of cleaning agent to keep my windscreen clean on the inside but somehow I don't seem to be able to get completely rid of the film deposit. Alcohol or ammonia based, household stuff or special car glass cleaner: nothing does the trick.
I'm looking for a cleaning tip that will allow me to thoroughly clean the glass surface.
By the way: I would expect the pollen filter to prevent compounds like anti-freeze being sucked into the car interior from the motor compartment, not?
