Disinfecting, Cleaning & Drying Procedures

CAUTION! These instructions apply ONLY to Kyocera rugged, also known as Dura Series, devices. If you are not sure if you have a rugged device, please contact our call center: 800-349-4478.

Your phone may be disinfected using alcohol (70% solution) or cleaning wipes. It may also be cleaned using a mild dish cleaner. Please see the recommended procedures below.


  • Remove all accessories, such as screen protector, phone case and cover, and strap. For details, refer to the instructions that came with your accessory.

  • Before disinfecting or cleaning, be sure the SIM/SD card slot cover is closed firmly to maintain the waterproof capability.

  • Never apply or spray alcohol directly on the phone as it can lead to damage of the coating and could affect its waterproof capability.

  • Never pour liquid cleaning agent directly onto the phone as this may affect the sound quality. If your phone is exposed to a concentrated liquid cleaning agent, rinse it immediately with fresh water.

  • Do not expose your phone to water at high pressure, and avoid immersing the phone in water for more than 30 minutes to maintain the waterproof capability.

  • Clean by hand only. Do not use a hard brush, abrasive sponge or any abrasive cleansers as these may damage the surface of the phone and affect phone’s waterproof capability.

  • Do not use a washing machine, ultrasonic cleaner, or dishwasher. Doing so may damage the phone and affect the waterproof capability.

  • Remove all jewelry to avoid scratching the surface of the phone.

  • Do not attempt to clean your phone in extreme cold or hot conditions. Water can penetrate the phone during a rapid temperature change. If the phone has been exposed to extreme temperatures, allow it to return to room temperature before cleaning.

  • To help keep the phone clean avoid handing the phone to other people. Consider using text messages or other online methods to share images and information.

  • Since phones can collect germs, avoid putting your device on public surfaces and consider using Speaker Mode or other methods to minimize touching the face with your phone.


Disinfecting the Phone


Cleaning Guide

Gently wipe the phone with a lint-free cloth moistened with alcohol (70% solution)* or a cleaning wipe.

*Note: Use only ethanol or isopropyl alcohol (70% solution).

Cleaning the Phone

CAUTION! Be sure the SIM /SD card slot cover is closed firmly to maintain the waterproof capability.


Turn off the phone.


Rinse the phone thoroughly under running water in order to remove dirt.


Add equal parts mild dish cleaner and warm water to a soft cloth. Using the cloth, gently rub the front and back parts of the phone in a circular motion.


Rinse all sides of the phone and all physical keys until there is no cleaning agent or residue left.

Note: Hold your phone below the faucet as shown below and rinse with low pressure tap water for more than 20 seconds for each part. Use only lukewarm water.

CAUTION! If any cleaning agent is left inside the phone, the audio quality as well as waterproof capability may deteriorate.


Dry your phone until you are sure there is no moisture left. See Drying Your Phone for details.

Note: Frequent and repeated cleaning may result in the surface gloss degradation, deformation, or discoloration of the phone.


Rinse the speakers, microphones, and earpiece under running water and make sure all bubbles are removed.


Put about 2 inches (5 cm) of water in a large bowl and gently rinse the phone by swirling it under water for about 10 seconds.

Drying Your Phone

CAUTION! If your phone has been submerged in water, for example to use the camera in Underwater Mode, be sure to rinse all surfaces of the phone thoroughly with clean, fresh water before drying.


Wipe down all outside surfaces of your phone with a clean lint-free cloth.


Wipe the back side of the phone.


Hold the phone firmly and gently shake it a few times to displace surface water.


Pat with a clean dry cloth to remove moisture from speakers, microphones (2), earpiece, and pressure adjustment hole. Repeat patting each area about 20 times.


After removing all the water, let the phone dry completely at room temperature.
