Hearing aids work in a demanding environment. They are exposed to earwax, skin oils, sweat, humidity, dust, and frequent handling every day. Without regular care, these substances can block sound openings, interfere with charging, and reduce performance.
A simple maintenance routine can help keep your hearing aids comfortable, reliable, and sounding clear. Always follow the instructions supplied with your specific model, since cleaning and replacement procedures vary between devices.
Understand the Main Components
Most hearing aids contain several essential parts:
- Microphone: Captures sounds from the environment.
- Processor or amplifier: Processes and adjusts incoming sound.
- Receiver or speaker: Delivers the processed sound into your ear.
- Battery: Provides power through a disposable battery or rechargeable cell.
- Dome or earmold: Holds the hearing aid securely and directs sound into the ear canal.
- Wax filter: Helps prevent earwax and debris from reaching the receiver.
Earwax blocking the receiver or microphone is one of the most common reasons a hearing aid may sound weak or stop working properly.
Clean Your Hearing Aids Every Day
The National Institute on Deafness and Other Communication Disorders recommends keeping hearing aids away from heat and moisture and cleaning them according to the manufacturer’s instructions. Earwax and ear drainage can damage a hearing aid if allowed to accumulate.
Follow these basic steps each day:
- Remove the hearing aids over a clean, dry surface.
- Inspect the domes, receiver openings, microphones, and body of each device.
- Wipe the exterior with a soft, dry microfiber cloth.
- Use a hearing-aid brush to remove loose wax and debris.
- Check whether the wax filter looks blocked.
- Place the devices in their charger, storage case, or drying system as directed.
Cleaning your hearing aids before bed makes it easier to remove sweat and surface moisture from the day. Dry earwax may be easier to brush away the following morning.
Clean Delicate Openings Carefully
Microphones and receivers contain small openings that can be damaged by aggressive cleaning.
When removing debris:
- Hold the opening downward so loosened material falls away from the device.
- Brush gently rather than pushing the tool into the opening.
- Never use pins, needles, toothpicks, or other sharp objects.
- Do not force a cleaning wire into a receiver unless the manufacturer specifically instructs you to do so.
- Avoid compressed air, which can push debris further inside.
If the sound remains weak after cleaning the exterior, inspect the wax filter and dome before assuming the device has developed an electronic fault.
Check Domes and Wax Filters
Domes and wax filters are replaceable parts that directly affect comfort and sound delivery.
A dome may need replacement if it becomes:
- Torn or cracked
- Stiff or discolored
- Loose on the receiver
- Uncomfortable in the ear
- Difficult to clean properly
Wax filters should be replaced when they appear blocked or when sound becomes weak despite a charged battery. Replacement frequency varies considerably because some people produce more earwax than others.
Only use domes and filters that are compatible with your hearing-aid model. A poorly fitted dome can become detached, cause feedback, or change how the device sounds.
Protect Your Hearing Aids From Moisture
Even moisture-resistant hearing aids are not necessarily waterproof.
Remove your devices before:
- Showering or bathing
- Swimming
- Using a sauna or steam room
- Applying hairspray
- Using spray deodorant, perfume, or other aerosol products
- Applying hair dye or similar treatments
If your hearing aids are regularly exposed to perspiration or humidity, use a hearing-aid drying jar or dehumidifier according to the manufacturer’s instructions.
Do not dry hearing aids with a hair dryer, microwave, oven, radiator, or direct sunlight. Excessive heat can damage the battery, casing, and internal electronics.
If a device becomes wet, switch it off if possible, dry the exterior, and follow the manufacturer’s instructions. Contact the manufacturer or hearing-care provider if it does not operate normally afterward.
Care for Rechargeable Hearing Aids
Rechargeable hearing aids require slightly different maintenance from devices powered by disposable batteries.
To maintain reliable charging:
- Place the hearing aids correctly in the charging case.
- Keep the charging contacts clean and dry.
- Use the charger and cable recommended for the device.
- Charge the devices according to the manufacturer’s instructions.
- Keep the charger away from sinks, bathrooms, and other damp areas.
- Avoid leaving the charging case in extremely hot or cold locations.
If charging becomes inconsistent, inspect the contacts for dust or debris before assuming the battery has failed.
A gradual reduction in runtime may occur as rechargeable batteries age. A sudden change in battery performance may indicate a charging problem, damaged cable, dirty contact, or device fault.
Care for Disposable Batteries
If your hearing aids use disposable batteries:
- Use the correct battery size.
- Store unopened batteries in a cool, dry place.
- Keep batteries in their original packaging until needed.
- Do not store loose batteries with coins, keys, or other metal objects.
- Remove dead batteries promptly.
- Wash and dry your hands before changing them.
Hearing-aid batteries can be dangerous if swallowed. Keep batteries and small hearing-aid components away from children and pets. Seek immediate medical assistance if a battery is swallowed.
Store Your Hearing Aids Safely
When they are not being worn, hearing aids should be stored somewhere clean, dry, and secure.
Avoid leaving them:
- In a bathroom
- Near a sink
- Inside a hot car
- On a windowsill in direct sunlight
- Loose in a handbag or pocket
- Within reach of children or pets
A protective case helps prevent drops and keeps the devices from being crushed. A drying container can provide additional moisture protection when appropriate for the device.
Avoid Common Cleaning Mistakes
Some well-intentioned cleaning habits can damage hearing aids.
Do not:
- Immerse the devices in water.
- Wash them under a running tap.
- Clean them with household solvents or disinfectants.
- Use alcohol unless the manufacturer confirms it is safe.
- Insert cotton swabs into microphone or receiver openings.
- Pull the hearing aids out by their receiver wires.
- Attempt to open or repair the casing yourself.
Only use cleaning products intended for hearing aids and approved for your particular model.
Maintaining Smartphone Connectivity
Smartphone compatibility does not change the physical cleaning process, but the companion app can help you monitor and manage some aspects of your devices.
Depending on the hearing aid and app, you may be able to:
- View the remaining battery level
- Adjust volume and listening programs
- Manage Bluetooth connections
- Install firmware updates
- Access setup or troubleshooting guidance
If the hearing aids stop connecting to your phone, begin by checking whether they are charged. Then confirm that Bluetooth is enabled and that the app and phone operating system are up to date.
Restarting the phone or reconnecting the hearing aids may resolve a temporary connection issue. Avoid resetting the devices unless the manufacturer’s instructions recommend it, because a reset may remove personalized settings.
When to Request Professional Help
Contact the manufacturer, hearing-care provider, or audiologist if:
- The device produces no sound after basic cleaning and charging.
- Sound remains weak or distorted after replacing the wax filter.
- Feedback occurs frequently.
- Battery life suddenly becomes much shorter.
- The hearing aid has visible physical damage.
- The receiver wire or tubing is cracked.
- The device becomes unusually hot.
- The hearing aid causes pain or persistent irritation.
- Your hearing appears to have changed.
Regular professional servicing may also identify internal debris, worn components, or programming issues that cannot be corrected with home cleaning.
Create a Simple Maintenance Schedule
You do not need a complicated routine to care for your hearing aids.
Daily
- Wipe the devices with a dry microfiber cloth.
- Inspect the domes and sound openings.
- Remove visible debris.
- Charge or store the hearing aids correctly.
Weekly
- Clean around microphone and receiver openings with a suitable brush.
- Inspect the domes and wax filters.
- Check the charger and charging contacts.
- Examine the devices for cracks or other damage.
As Needed
- Replace blocked wax filters.
- Replace damaged or worn domes.
- Use a drying system during humid conditions.
- Contact support if performance changes.
Keeping the necessary supplies together makes this routine easier. An all-in-one kit for cleaning, drying, and replacing essential hearing-aid parts can help you avoid searching for individual tools when maintenance is needed.
Consistent Care Supports Consistent Hearing
Hearing-aid maintenance does not need to take long. A few minutes of daily cleaning, combined with proper storage and regular inspection, can prevent many common performance problems.
Keep your devices clean and dry, replace consumable parts when necessary, and follow the instructions supplied with your model. If basic troubleshooting does not resolve a problem, seek assistance instead of attempting to repair delicate internal components yourself.
