Faint light gray square outlines on MacBook Air screens with M2 or M4 processors, even when devices are off

First, thank you for the fast comment. No I do not have any "skin" on the keyboard, and second it is NOT a reflection of the keyboard. No mater how I move the screen the outlines never move, even if I cover the keyboard, they are in the screen. I know this because when I clean the screen several times, which I did not do in the pictures because the issue is the squares not my screen hygiene, the squares sometimes go away, if I use enough pressure. But not enough to damage the screen. When I use the computer and there is a white background they appear. They form in a row, sort of cut and paste style. I have turned off all the startup programs that run in the background as well start in safe mode and no luck, still there. I do appreciate your effort, thank you.

Greetings again,

Thank you thank you KiltedTim for the suggestion of the "skin". In the past one was used and your comment got me to thinking so I got better lighting and looked more closely at the blank screen and sure enough I did see other very, and I mean very, faint outlines on other portions of the screen. As you suggested those very faint outlines did indeed line up with some keys. You are very astute and your idea was spot on. I used a stronger glass cleaner because I assumed, correctly, that the images might be silicone which is hard to remove. Now the black screen is smudge free and image clean. Thank you so much. If I an give you a "thumbs up" I would.

Thank you for the advice and link
