I am not really sure what is going on. When I wash my war, I notice the water just pearls off when it rains, so why do you have a smear?
I have an older car, so the windscreen is many years old. I use a glass cleaner such as Mr Muscle and when the glass is wet, I have used window sc r a p e r. Most tap water as used in car washes or rain water contains minerals. Cleaning does n't remove it.

I have to do this on the inside of the car too.
It does take time.
I then maintain it with autoglym fast glass cleaner with a microfibre cloth.
Update: The link does not work, as this web site has changed the word sc***er to ****
does now - Mod
