Maintenance & troubleshooting

Hearing aid maintenance is important for well-functioning and long-lasting hearing aids. Even though hearing aids are very durable and can withstand the stresses of daily use, hearing aid maintenance is necessary to make sure you’re getting the best sound quality and longevity out of your devices.

Care and maintenance

Daily

Remove your hearing aids when applying cosmetics, perfume, aftershave, hair spray and suntan lotion as they may get into the hearing aid and cause damage.
Clean your hearing aids using a soft cloth, tissue or proper cleaning tools to remove earwax, grease or moisture. Do not use water or solvents as these can damage the hearing aids.
Store your hearing aids in a cool, dry place when not in use and leave the battery pack open to preserve battery power.

Regularly

Use a damp cloth to clean the receiver tube and receiver dome.
Do not use a direct source of water when you’re cleaning the receiver tubes or the receiver domes.
Contact your hearing care professional for replacement components when they become stiff, brittle or discolored.

Other tips

Keep your hearing aid clean and dry:

Never immerse hearing aids in water or other liquids or wear while showering, swimming, in heavy rain or in a moist atmosphere such as a steam bath or sauna.
Leave wet hearing aids to dry with the battery out and the battery door open.
Put the hearing aid and battery in a sealed container together with a drying agent (dessicator) overnight. Don’t use the hearing aids until completely dry.
Don’t leave your hearing aids in or near direct heat or sunlight.
Avoid rough handling of hearing aids or dropping them on hard surfaces or floors.
Read the instructions for your hearing aids or contact your hearing care provider for additional hearing aid maintenance instructions.
