alicia, please remember that rice is a great first aid, but it does not stop corrosion nor does it fix any burned out SMD components. Do not waste valuable time to place your phone in rice and wait even longer. I strongly suggest that you disassemble your phone and clean every part with 90%+ isopropyl alcohol. Use a small brush to do so and do not forget to clean under all the EMI shields etc. Once cleaned (you may have to do it a couple of times) reassemble your phone, replace the battery and re-evaluate. Hope this helps, good luck.
Does the phone still turn on at all/show any signs of life? And also what liquid was spilled onto it? We need more info!!
Anyway, the best thing to do is remove the casing so the phone's logic board is exposed (This isn't needed so don't do so if you aren't confident but it speeds up the process). And then put the phone in a bag of rice ensuring the whole phone is covered (The rice absorbs moisture) and leave it on a windowsill in the bag of rice for a few days to a few weeks depending upon how bad the water damage was.
Please note: If you disassemble the phone ensure all electrical parts are placed in the bag as all of them could've been damaged.
