Putting electronics in rice after water damage is a popular DIY fix, but does it really work? There are a few things to consider when deciding if rice can save your wet phone, tablet, or other device.
How Does Rice Work?
The theory behind using rice is that it will absorb moisture from the inside of your electronic device. Rice is hygroscopic, meaning it naturally absorbs water molecules from the air. When you submerge a wet device in rice, the rice will slowly extract the water over time.
Rice is often recommended over other household desiccants like silica gel packets because it is inexpensive and readily available in most homes. The small size of rice grains allows moisture to be wicked away quickly as well.
Does Rice Actually Work?
There is some debate over whether rice truly “fixes” wet electronics. Some repair experts claim that rice cannot remove enough water to make a difference. Studies have shown rice only absorbs around 12% of its weight in water. This means that a cup of rice can only absorb about a tablespoon of water.
For major water damage like dropping a phone in the toilet or swimming pool, a tablespoon of water absorption will not be sufficient. The liquid is likely permeated deep inside the device, beyond what surface-level rice can extract.
When Might Rice Help?
While rice may not work for severe water damage, it could be beneficial for slight moisture exposure. Here are some instances where rice may be able to absorb enough liquid to revive the device:
- Getting small splashes or drops on the device
- Exposing device to humid environments like steam from a shower
- Getting caught in a light rain shower
The key is that the water exposure is minor and has not seeped deep inside the electronic components. With just a bit of light moisture, rice can potentially draw it out over 24-48 hours.
Tips for Using Rice
If you do decide to use rice on a slightly wet device, here are some tips to maximize effectiveness:
- Use uncooked rice – this provides more surface area to absorb moisture.
- Bury device fully in rice so it has contact on all sides.
- Allow 48-72 hours for moisture to be absorbed.
- Stir and replace rice as it becomes saturated.
- Start process as soon as possible before moisture can damage electronics.
- Remove any accessories like cases so rice contacts the device directly.
Other Alternatives
While rice may work for minor wetness, it is not the most effective method, especially for severe water damage. Other options include:
| Method | How It Works |
|---|---|
| Silica Gel Packets | Absorbs more water than rice. Up to 40% of weight. |
| Isopropyl Alcohol | Displaces water and speeds up evaporation process. |
| Vacuum Chamber | Uses pressure differential to literally suck water out of device. |
| Professional Data Recovery Service | Uses specialized tools to dry out device and repair damaged components. |
Conclusion
Rice can potentially revive electronics after minor spills or moisture exposure. For major water damage, however, more heavy duty drying solutions are likely required. Rice is worth trying for slight wetness, but do not rely on it alone to save a device from significant water damage.
