To prove it one way or another.

Clean the cabin. Take it for a drive on an empty damp road and repeat on a damp road in traffic.

If purely the vertical screen then on empty road it should remain clean.

I do like Jays idea sellotape 1 metre bits of wool to the top of the windscreen and film the results.
