New 3DS XL Sceen Problem

[Mrsmashy]

The other day I was cleaning my 3DS when I noticed some white marks on the screen, I need help and would be helpful if someone tells me why this happens and is there any way to fix it. It started with a big white mark then it started to get smaller i got pics

What exactly were you using to clean it?

What exactly were you using to clean it?

91% alcohol just for the exterior, for some reason the bottom screen had some marks too but disappeared the next day, the top screen kind of did the same thing but there is still some marks like the first pic

If no one is replying, then evidently no one knows.

If you have a screen protector, then fluid may have gotten underneath the screen protector.

They look like moisture stains. I had a humidity problem on an old 2ds screen and I solved it by opening the screen completely and cleaning the screen sheets.

91% alcohol have 9% water content, t seem like you got water inside the screen now.
