Just dropped my iPhone 6S in the toilet, is it done for? What can I do?

Nothing was in the toilet and yes, I still use an iPhone 6S. I need the headphone jack.

I removed the case it was in and then thoroughly cleaned it with alcohol wipes, it's now lying in a bowl of rice.

This happened 10 minutes ago but I only turned it off 2 minutes ago before I put it in rice.

Is there anything else I can do to salvage my phone?

The screen had vertical lines in the background, like a wallpaper, kinda like this picture but nowhere near as bad. I could still see everything clearly and interact with the phone.
