A long time ago my now-wife got water in the lens of her Canon point-and-shoot. We bought these and they seemed to do the trick after a few days. Slowly the spot shrunk until it was gone.
The nice part about those desiccant packs is that you can put them in the oven to "recharge" them.
Good luck, and report back here to let us know if it worked.
You want reusable ones: https://www.amazon.com/Hydrosorbent-OSG-40-Dehumidifier-Desiccant-Chloride/dp/B015OT106O/ref=sr_1_5?s=home-garden&ie=UTF8&qid=1488241398&sr=1-5&keywords=reusable+silica+gel
However, these will need frequent drying if in an unconditioned space in a humid climate.
Another option is a goldenrod. Is is a small(12W for the 12" model) electric heater that keeps a closed volume a few degrees warmer than the surrounding environment. This creates a microclimate that prevents condensation on the protected metal things.
Umm, no. Rice absorbs almost no moisture at room temperature (see http://www.payetteforward.com/my-iphone-got-wet-what-do-i-do/2/). What you're doing by leaving it in an uncovered bowl of rice is nearly identical to just leaving it out on the counter. If you have instant rice it will act as a very mild dessicant, but standard rice is just a placebo.
The best way to get 90% of the water out is to just leave the phone out in the open with a fan blowing on it, assuming that your indoor humidity isn't too high (If you have either your furnace or air conditioner running, your indoor humidity should be fine). A room full of indoor air can absorb a huge amount of moisture.
Once the phone is mostly dry from sitting out, you can put it in a very low humidity environment to get out the last of the moisture. This means sealing it with a strong dessicant -- something way more powerful than rice. Your best bet is to get some calcium chloride (if you live in a snowy area hardware stores will sell it as a deicer or ice melt, otherwise you can get it in the canning section of a supermarket where it's sold as "Pickle Crisp"). If you can't get CaCl, you can also get a reactivatable silica gel cartridge such as http://www.amazon.com/Hydrosorbent-OSG-40-Dehumidifier-Desiccant-Chloride/dp/B015OT106O. Wrap the phone in a handkerchief or hand towel and seal the it in an airtight container or jar with the silica gel or calcium chloride for a few days.
