IPhone got water in it and won't turn on?

So the other day on vacation i went to the pool and i used my life proof case to go under water and take pictures. After i got out of the pool i took off the case and noticed my phone was all wet. I'm pretty sure a few drops of water went into my phone. I was normally using my phone until it just shut off. After a few minutes of panicking i went back to the hotel room and the phone was hot and had many strange lines on the screen. Not knowing that charging the phone would damage it more i charged it for a good 3 hours. When i got home from my vacation i put it in a bag of rice. Its only been a day since it happened and my phone won't turn on still. Do you think i should take apart my phone and clean the motherboard with alcohol and change the battery? I really need the pictures on that phone because it had very special pictures and i wasn't home so my phone didn't back up! Please someone tell me what to do! Don't give me any too harsh answers and if anyone out there's an expert please help!

Take your iPhone to repair center and dry it well. After doing good interior service, Try turning on the phone back. But I can't guarantee it works.
