Wet iPhone 5s, can it be saved?

I was doing the dishes, splashed it didn't realise how sensitive the little **** is so ignored it until I went to bed then I wiped it. I used it for hours noticed a bit of water at the bottom of the screen then fell asleep and next thing its the morning the phone shows nothing on the screen but I can hear everything. Its been a day its in rice still screen shows slight lighting nothing on it sound is still there. Tried the vacuum as well for 10 minutes nothing. Is it gone for good?

You could always try this, it was on Dragons Den. No idea if it works but the reviews seem average -

Water and cell phones don't mix You should have shut it off right away put in the bag if rice for a couple of days Its never going to be the same and probably is garbage

Hope it helps
