How to fix an iPhone 5C that fell in the pool and now won't connect to iTunes?

So about a month ago, I dropped my iPhone 5C in a hot tub. I pulled it out immediately. (It was in the water for maybe two seconds) It was still playing my music and it seemed like everything still worked. I dried it off as well as I could. We didn't have rice on hand and it was late at night so I never did that. A few days later, I went to plug it into my computer to upload some new music and now it won't connect to iTunes. It still charges the phone, but it won't show up in iTunes. Every time I plug it in, a message pops up saying USB not recognized. I have tried several different cables and I'm pretty sure nothing is wrong with my laptop. I'm not sure what to do to fix this. Any ideas?

If it has water damage tehn you need a professional to look at it.
