Rubbing Alcohol Inside Phone

I brought my XR to have the battery replaced. Once I got it back I noticed something was wrong with the screen. I brought it back and the technician said that it was probably rubbing alcohol that wasn't completely dry. She replaced the screen and everything seemed to work fine until I plugged it in to charge. When I plugged it in the phone started glitching and most of my screen was unresponsive. I brought it back again and she said she probably used too much and she will let it dry out for a few hours. Now I'm wondering if my phone will ever work properly again. Is my phone fried? Thanks!
