Spilled Milk Coffee on iPhone 11

Hello, I spilled my coffee after it tangled with the charge cable of my laptop and it also made it on my phone. I quickly took the phone and wiped off the milk. As per apple’s suggestion on the website, I rinsed the earpiece speaker with water.

I also tried playing “water removing” sounds on youtube. Earpiece speaker is not completely dead, but it sounds muffled. Any suggestions on what I can do?

Happened approx 2 hours ago. I read that it takes around 24h to completely dry. I wanted to know if there’s anything extra I could do. Thanks
