Keep hearing aids dry
Moisture is one of the common enemies of hearing aids. Keep devices away from water, steam and excessive humidity. Remove them before bathing or swimming unless the exact device is specifically designed for that environment.
Clean the hearing aid regularly
Follow the cleaning instructions for your exact model. Wipe the exterior with a dry or manufacturer-approved cloth and keep microphone openings clear. Do not push sharp objects into ports or use household cleaning liquids unless the manufacturer specifically permits them.
Manage earwax and wax filters
Earwax can block sound openings, domes or wax filters and may contribute to weak sound or feedback. Inspect the parts regularly and replace filters or domes according to the device instructions. If you have frequent wax buildup, ask a hearing professional about a suitable cleaning routine.
Charging and batteries
For rechargeable devices, place the hearing aids in the charger as instructed and keep charging contacts clean and dry. For disposable-battery devices, use the correct battery size and replace depleted batteries promptly. Keep batteries and small hearing aid parts away from children and pets.
Store hearing aids safely
When you are not wearing the devices, keep them in a dry, safe case or the recommended storage system. Avoid leaving them in direct sunlight, a hot car or near a heater. Turn them off when the device instructions recommend it.
When to get professional service
If the hearing aid sounds weak, distorted, intermittently cuts out, whistles unexpectedly or stops charging, professional inspection may be needed. Do not keep using a damaged device simply because it still produces some sound.
A simple weekly maintenance checklist
- Check the sound opening and wax filter.
- Clean the external surfaces as instructed.
- Check domes, tubing or earmolds for wear.
- Inspect charging contacts if rechargeable.
- Store the devices correctly overnight.
- Arrange professional servicing when performance changes.
Frequently Asked Questions
How often should hearing aids be cleaned?
Light external cleaning should be part of your regular routine. The exact schedule for filters, domes, tubing and professional service depends on the model and your earwax or moisture exposure.
Can I use alcohol or sanitizer to clean my hearing aids?
Do not use household liquids unless the manufacturer specifically says they are safe. Follow the cleaning instructions for the exact hearing aid model.
Why is my hearing aid suddenly weak?
A blocked wax filter, dirty sound opening, moisture, low battery or a device fault can reduce output. Check the basic care steps first and seek professional service if the problem continues.
