Dropped my iPhone 5 in Sprite?

Not my iPhone but my mom's. In the car in the cup holder there was a small plastic cup of sprite. It wasn't all the way full but my mom placed her phone in the cup thinking it was empty so now it freezes and the screen motion is tough like if you try sliding the screen you have to slide it really hard to get it move all the way. And it freezes up so what should I do?

Put it in a bag of dry rice overnight. That helped me!

Ouch, you can try the rice trick but that's better for water, When water dry's it leaves nothing behind, However with Sprite. It contains sugars and such that still leaves behind a sticky residue that is conductive. I would recommend backing the phone up now if it still works. Chances are it won't for much longer.

Take it to the apple store and they might replace it for free. I've had plenty of issues with my iphones and I got free replacements each time. But I believe water damage might be a different story. If the inner part of the phone is fried and not fixable they might turn you down. I had water damage on one of my phones and thankfully what ever got messed up was an easy fix for them.

Dry rice in a bag for a day or two.
