Rice can transform an economy, save a boring meal, and stop winter drafts. One thing it absolutely, positively cannot do is save a wet cell phone. In fact, submerging your phone in rice makes the problem worse, especially if it’s still powered on.

Say it with us: Rice is a food, not a tool. Food rice good, phone rice bad.

Okay, you’re still here, good. Let us delve into why submerging your phone rice—or kitty litter, or dessicant packets—right after it gets wet can’t do anything for your soaked phone.

Side-by-side images of phone insides: this is your phone, this is your phone on rice
There is no higher authority on repairing water damage to modern electronics than Jessa Jones, owner of iPad Rehab repair service. Jessa’s entire repair career started with an iPhone trapped in a toilet by toddlers, freed by a sledgehammer. That led her down a long series of rabbit holes, to where she’s now a water damage and microsoldering expert. Jones wrote a wiki guide to the rice-fixes-water myth on this very site, and it’s a good place to start busting the myth:

Corrosion is instant when a phone hits water. Sometimes the corrosion hits important components, sometimes not. If we resist turning the phone on until it dries on the counter, in the rice bag, or anywhere else, sometimes we get lucky. If we had the phone in the rice bag, we think the rice saved the phone. But it didn’t! Even if the phone seems to be working, it will have oxidized solder joints that are weakened and brittle. Corrosion will continue to spread inside the phone. We have done nothing but experienced temporary luck.


Read on and Jones gives the real solution: disassemble the phone, immerse it in alcohol to displace water and loosen bits of corrosion, and scrub. We’ve detailed the entire water-damage repair procedure in a guide. Here’s the short, bulleted version (that you absolutely cannot rely on if you’re holding a water-logged phone right now, please read the full guide):

Minimize exposure to water as much as possible
Power the device off immediately
Drain the device to get as much water out as you can
If you can remove your phone’s battery, and you can see it’s been exposed to water, remove and replace the battery
Remove the logic board and other parts that appear corroded (except the camera and display) and immerse them in 90% isopropyl alcohol.
Scrub the immersed parts, dry the alcohol, and meticulously reassemble.
That’s not a short, easy procedure. Also, if your device is already waterproofed in some way, you can compromise its sealing by opening it up. If you don’t have the means or time to run through this procedure, or pay a qualified repair shop to do it, you can simply leave your phone out to dry, opened up and exposed as much as possible.
