Cleaning a phone regularly is important, but doing so improperly can damage your phone and cause it to malfunction or cease working. Please follow the guidelines below for effectively cleaning your VoIP phones.


Before Cleaning

To prevent the spread of viruses and bacteria, consider doing the following before interacting with Poly products:

  • Wash your hands based on CDC guidelines.
  • If available, put on disposable latex or nitrile gloves.

Cleaning Methods and Solutions

Read and understand the following guidelines before cleaning and disinfecting your VoIP phones. Failure to follow these guidelines can result in damage of the equipment or harm to individuals.

  • Always power off and disconnect cables from a phone before cleaning.
  • Always clean phones wearing disposable latex or nitrile gloves and in a well-ventilated area.
  • Do NOT use harsh chemicals—such as bleach, peroxide, ethanol, acetone, ethyl acid, methyl chloride, ammonia, or multi-purpose cleaners—to clean plastic, metal, rubber, or screen surfaces.
  • When using isopropyl alcohol, make sure it is medicinal grade. Industrial-grade isopropyl alcohol can corrode some surfaces.
  • Always use a clean, dry, microfiber cloth to wipe phones.
  • Always spray cleaning solutions on the cloth before cleaning the phone but be careful not to oversaturate the cloth.
  • Never apply or spray the solution directly on the phone because the liquid could stain or seep inside and damage the hardware.
  • Always let the device air-dry completely before reconnecting any cables.
  • If you have an ultraviolet germicidal irradiation (UVGI) device that emits UV-C radiation, unplug the phone and place it in the UVGI device for 1-2 minutes.
  • After cleaning phones, wash your hands based on CDC guidelines.
  • Keep a record of cleaning frequency near all high-use devices, such as a conference phone, and update it after each cleaning.
Caution: Be aware that if you use germicidal disinfectant wipes to clean phones, the wipes will cause some level of visible or functional damage to the hardware over time.

Cleaning Touchscreen and Non-Touchscreen Phones

It is recommended that you regularly clean the screen on all touch-enabled phones located in high-use spaces, such as conference rooms and lobbies. When cleaning conference phones, desk phones with keypads, or handsets, base stations, or sidecars, be careful to not let any of the disinfecting solution seep into the phone or accessory.

  1. Unplug all cables from the phone or device.
  2. Spray a medicinal isopropyl alcohol and water solution of 70:30 onto a clean, dry, microfiber cloth, making sure to not oversaturate the cloth. Should oversaturation occur, squeeze out any excess liquid before wiping the surface.
  3. Quickly wipe the screen with the dampened microfiber cloth. Always use the dampened cloth with the alcohol solution to clean screens, and don’t let cleaning solution pool on the surface. Don’t use chemicals to clean the screen.
  4. Let the touchscreen and surrounding areas air-dry completely before reconnecting any cables.
Note: You can also use an alcohol cleaning solution of up to 99% to clean touchscreens to reduce the risk of seepage and quicken the drying time.
