Iphone 5 orange juice damage

I have a new iphone 5 just diped it in tinny little orange juice spilled at the bottom where the charger and spekers are. Immediately I realized the speakers won't work properly they work when my phone rings but when I try to play media they won't work. Also the mic seems to not work. I put it in rice for an hour now I don't know what to do. All the service centres are closed now it's late. Should I keep it in rice?
Please give me practical asnwers. If there's a permanent damage can I replace the speakers and mic?

Keep it in rice overnight and keep it turned off. Speakers are easy to replace on the iPhone 5 anyways.
