Reach out to the manufacturer of your devices for recommendations on how to properly sanitize the equipment as well as review guidance provided by the Center of Disease Control on Cleaning and Disinfecting Your Facility, which includes recommendations for electronics. Below are general strategies to properly sanitize equipment:
Make sure to wash your hands before and after cleaning the device.
Use disinfectant wipes that contain between 60-70% ethanol.
Take care to never submerse equipment in any liquid or permit liquid to get inside of microphones.
Make sure equipment is completely dry prior to using again.
We also recommend reviewing the article How to clean your hearing technology and asking members on the NDC listserv for additional disinfecting strategies for assistive listening devices.
