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.”

results, a video demonstration of TekDry’s technology, and an
infographic illustrating the study and including device rescue tips and

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