Rice Myth Busted: New Study Proves Using Rice to Dry a Wet Phone Is Not Effective

DENVER–(BUSINESS WIRE)–A new scientific study released today by TekDry (www.tekdry.com),

an emergency electronic device rescue service, shatters the widespread

myth that placing a wet smartphone in a container of rice is an

effective way to dry it.

The study, “Evaluation of Rice as a Method of Drying Out Waterlogged

Cell Phones,” was conducted by DTJ Consulting and was commissioned by

TekDry to explore the commonly held belief that placing a wet smartphone

in a sealed container of rice for 48 hours effectively removes water

from the phone.

“The optimal window of opportunity to restore a wet electronic device is

less than 48 hours and it’s always best to act as soon as possible,”

said Adam Cookson, TekDry’s co-founder. “The study clearly demonstrates

that consumers should think twice before wasting crucial time with rice.”

The study not only proves that rice is not an effective drying agent,

but that it is actually less effective than simply leaving the device

out in the open to dry naturally on its own – but neither method will

thoroughly dry the device.

“After monitoring the weight loss of a phone simulator placed first in

an open room for 48 hours and second in a container of rice for 48

hours, both times containing the same initial weight of water at the

same temperature, evaporation reduced the water weight of the device

left in an open room by 14.7 percent while enclosing the device in a

container of rice reduced the water weight of the device by 13.1

percent,” said David James of DTJ Consulting. “The results also clearly

demonstrate that both evaporation in a room and a closed container of

rice did very little to dry the device in 48 hours.”

DTJ Consulting created a smartphone simulator for this experiment

because a waterlogged smartphone drips through openings and seams in its

case, which makes it impossible to isolate and measure the weight loss

only due to evaporation in a room or placement in a closed container of

rice. The simulator is a plastic box with openings in the top totaling

42mm2, representative of the openings in current phone

designs. The simulator contained a small folded piece of wet paper towel

with a water weight equal to 10 percent of the volume of a selected

smartphone, because the internal spaces of a smartphone occupy

approximately 10 percent of its total volume.

“More than 22 million Americans lose their mobile devices to toilets,

swimming pools, washing machines, drink spills, and other aquatic

accidents each year and many believe the commonly held misconception –

perpetuated on the Internet and in the media – that using rice to absorb

water from a wet mobile device will dry and restore your mobile device

to working order,” said Eric Jones, co-founder of TekDry. “This study

lays the rice myth to rest.”

A detailed description of the rice experiment design, methodology, and

results, a video demonstration of TekDry’s technology, and an

infographic illustrating the study and including device rescue tips and

statistics regarding wet mobile devices, are available on TekDry’s

website.

TekDry’s patented device-rescue service completely restores within 30

minutes wet mobile devices including smartphones, laptops, tablets, and

cameras, saving consumers time, money and the hassle of dealing with

high insurance deductibles and costly device replacement fees.

TekDry recommends the following list of tips to save a wet phone:

1. DO NOT plug in your phone – Electricity and water just don’t mix.

2.

DO power off the phone – This will help prevent a short circuit.

3.

DO remove the battery if possible -Separating the battery from the phone

helps to keep electricity away from the waterlogged components. This

minimizes the chances of irreversible damage.

4. IF it was dropped

in salt water, DO rinse it in fresh water – Salt water will almost

certainly corrode and short the phone and will do more damage than fresh

water, so it is best to remove any traces of salt water quickly.

5.

DO dry with paper towel or washcloth – Removing any visible water from

the phone will keep it from seeping into the phone and doing more damage.

6.

DO NOT use rice – This method is ineffective as demonstrated in the

study announced today.

7. DO NOT use a blow dryer or oven – The

heat from these methods often warp and damage the sensitive equipment

inside your phone.

8. DO NOT use a microwave – A major component of

electronic devices is metal and metal in a microwave is a recipe for

disaster.

9. DO call TekDry – TekDry’s technology is most effective

when implemented as soon as possible within the first 48 hours. If your

phone can’t be restored, you pay only a small portion of the shipping

cost.
