Graph screens, Screen cleaning

[Fozzy47]

Is there a consensus on how best to thoroughlyvclean your graph screen without damaging any protective film?
I have noticed a purple/bluish film on my screen reduces the screen clarity. I would love to remove this annoying film, but not want to damage the graph screen or any protective film.
Does anyone have any ideas?

Thanks,
Cheers,

I went to my optomotrist and got a small bottle of cleaning solution for eye glasses, both glass and plastic some time ago

I also never touch my screens unlike many I have see cause its easy to get as scratchmark
