Has anyone ever had the scenario where they have been driving and been basically sandblasted by a truck (behind it) , and had shitloads of sand engrained into the windscreen? Basically the sand will not come off. It's like the sand is glued to the windscreen.

When using the wipers it's no longer smooth and unpleasant. Rubbing your hand over the windscreen you can feel all the sand.

Any easy ways to fix, or up for a complete replacement?

Going to try and high pressure hose it but not confident it will get the sand off.
