Daily:
- Remove your hearing aids when applying cosmetics, hair spray, suntan lotion, perfume, and aftershave 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 receiver tubes or the receiver domes.
- Contact your hearing care professional for replacement components when they become stiff, brittle or discolored.
Other Tips:
- 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 (desiccator) 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.
