Little alcohol mistake after changing battery.

Hello,

I got a new battery and during the phase where you remove the old battery I used alcohol at first (Ethyl alcohol 99% NOT Isopropyl) and ignored the warning about spilling and I also had no tool for heating. I had no success and spilled the alcohol. I bought the cheepest hair dryer and finally got it out.
Anyway long story short, after I turned my Steam Deck on I saw the damage (?) as seen in the pictures.

Did I ruin the screen and need a replacement or is it possible to clean?
