Last wash of the bike the screen stained with our hard water area droplets. Whatever I tried to clean off with just left them - until this. Mooching around in the cupboard came across shower clean daily shine. Seems to work a treat.
Has anyone tried AutoGlym Fast Glass? It’s pH neutral, so could be worth a go.

That’s a polish, not a cleaner. No way would I put a cutting agent on anything like this.
Fast Glass is a gentle cleaner and different product altogether.
