How to best dry out some wet exterior buttons?

A

AC Question

Rookie mistake today. Carried my S6 Edge in my jeans pocket on a two hour canoe trip and ended up tipping into the river. I think all told the phone was underwater in my pants for about 2 seconds. Thankfully everything seems to be functioning perfectly with the exception of the right-side exterior on/off button as well as the bottom home button. At the moment those two are unresponsive. (The left-side volume buttons are working as normal.)

So can anyone tip me off as to the safest and fastest way to dry out the connections under those buttons?
