Got rainwater in MacBook Air leaving water stain on laptops screen

Good Afternoon Everyone,

About two days ago I was walking with my laptop in my bag and got caught in a storm. My Macbook Air got wet, but I wiped it off. I turned it on and everything seems to be working fine, except for a fairly large water stain that persists on the screen. I tried putting it in a bag of rice for a day followed by letting it hang a certain way to let the water drain off for two days but if anything, the stain got slightly larger. It turns on and types like normal so other than the stain, things still seem to be as normal.
