No, rice does not effectively dry out a cell phone. Research shows uncooked rice absorbs moisture at a rate of only 2-3% of its weight, which is too slow to prevent internal corrosion. Use silica gel packets or simple air drying instead.

For decades, the internet has claimed that submerging a wet phone in a bowl of uncooked rice will draw out moisture and save the device. The idea sounds plausible—rice is a desiccant, after all—but the reality is far less effective. A 2014 study by Gazelle (a device trade-in company) found that rice actually slowed drying compared to open air, because it blocked airflow and introduced starch dust into ports. Despite this, the myth persists on social media and in casual advice circles.
Why Rice Fails to Dry Phones
Rice is a hygroscopic material, but it absorbs moisture very slowly—only about 2-3% of its own weight over 24 hours. Meanwhile, a phone's internal components can corrode in minutes. The real enemy is not water itself but the minerals and impurities left behind after evaporation, which create conductive paths that short-circuit the board. Rice does not remove those minerals; it only tries (and fails) to remove liquid. Additionally, the grains can lodge in charging ports, speakers, and buttons, causing further mechanical damage. The Federal Communications Commission (FCC) does not regulate home drying methods, but repair professionals universally advise against rice.
Proven Drying Methods That Work
If your phone gets wet, act quickly. Turn it off immediately and remove the case, SIM card, and any removable battery (if possible). Do not plug it in or press buttons. Then use one of these methods:
- Silica gel packets — These absorb up to 40% of their weight in moisture. Place the phone in a sealed bag with several packets for 24–48 hours.
- Air drying — Position the phone upright in a well-ventilated area, ideally with a fan blowing on it. Avoid heat sources like hair dryers, which can warp components.
- Isopropyl alcohol bath — For severe submersion, a soak in 99% isopropyl alcohol displaces water and evaporates quickly without corrosion. This is an advanced technique best left to professionals.
A comparison of common drying methods:
| Method | Moisture Absorption | Risk of Damage | Time to Dry |
|---|---|---|---|
| Rice | 2-3% | High (starch, particles) | 24+ hours |
| Silica gel | up to 40% | Low | 12–48 hours |
| Air drying (fan) | N/A (evaporation) | Very low | 24–48 hours |
| Isopropyl alcohol | N/A (displacement) | Medium (if not pure) | 1–2 hours |
When to Seek Professional Help
If the phone does not power on after drying, or if you see corrosion on the charging port or camera lens, it is time to visit a repair shop. Internal corrosion can continue for days after the initial wetting. Professional repair technicians use ultrasonic cleaning with specialized solvents and can replace damaged components. The average cost for a water-damaged phone repair in the US ranges from $150 to $300, depending on the extent of the damage. Many major carriers and third-party shops offer diagnostic services for free or a small fee. Do not attempt to open the phone yourself if you lack experience—you may void any remaining warranty.
Preventing Liquid Damage
An ounce of prevention is worth a pound of repair. Consider these strategies:
- Use a waterproof case — Many models now offer IP68-rated cases that protect against submersion up to 1.5 meters for 30 minutes.
- Avoid risky environments — Keep phones away from pools, bathtubs, sinks, and rainy outdoor tables.
- Check your insurance or warranty — Some major carriers include water damage coverage in their equipment protection plans. Review your policy before an accident happens.
- Act fast — Even with a waterproof phone, saltwater, soap, or other liquids can damage seals over time. Rinse with fresh water and dry promptly.
By following these steps, you can reduce the likelihood of needing a costly repair or replacement. Remember: rice is not a solution—it is a myth that can cost you your phone.
