how to remove keyboard marks on laptop screen, which is only visible on light background?

[a1410]

i notice my laptop has a keyboard marks in a light background in the screen and when i try to shut down, the keyboard marks are not visible on the screen . i tried cleaning it but it didn't work that much  i don't know whether it's a dirt or from pressure since this is the first time that thing happened,  i hope you can help me about this issue and concern how to remove it and how to avoid such circumstances. thank you

Try a microfiber cloth or possibly a matching keyboard shield

IBM had one of the worst designs, that dot would put a dent in the screen
