Alcohol mark under AMOLED Display

Hello everyone I recently bought a Galaxy S4 in mint condition.. Everything was fully functional except the home button, which was "stuck".. So I went searched on GoogleLand and found that alcohol could help fix the stuck home button.. It worked!

But to be honest I must've out too much alcohol and now it seeped under the display. This phone has no water damage it's just that the bottom of the screen turned green-ish.. Any way to fix this? I tried rice and some heat.. PLEASE HELP ME! Ill post a photo if once I figure it out
