Spilled tea on my IPhone. Help!!!

Now Shenzhen   |   August 24, 2021

My girlfriend accidentally spilled some tea on the IPhone I bought three months ago. Does anyone know what to do? I tried to turn it off, and after this the phone just froze, and just kept displaying the Apple Logo. I left it for a few days until it used up all the battery, and now I can not turn it on. Can not do anything with it. Any suggestions?
