Is it possible the clean these stains on the scrern?

Hello guys,

First of all, I don't know if it's the right section, so my apologize if I posted in the wrong area.

I'd like to know if can I clean these stains off from my laptop's screen?
I've tried screen liquid cleaners but I've not got any success.

Is these stains permanent?

Thanks for help.
