How to get water out of my iPhone?

I dropped my phone in water and we took it to Verizon and they somehow fixed it but you can still see a water mark in the phone when you turn the phone on, and the cameras not working. Is there any way I could actually get water out of my phone? Or will I have to just get a new phone?

Switch to android. But if your still gonna stick with iphone, i suggest placing the fone in a bag of rice so it can soak up the water
