Question White spot on monitor

[Aisy]

Hey! I tried to clean my screen because some food got on it, and when i did it with a glass wiper, there was a small white spot. it's only visible in some spots. any ideas what it could be?

I can't see it anymore. Maybe it was just the fact that i touched it too hard or something but it seems to be gone now.
