Daily Rituals: The Foundation of Longevity

Consistent daily care is the bedrock of hearing aid longevity. It prevents the insidious build-up of earwax, moisture, and debris, which are primary culprits in device malfunction.

The Evening Wipe-Down: A Simple Yet Powerful Act

Every night, before storing your hearing aids, perform a thorough wipe-down. This removes the day’s accumulation of skin oils, sweat, and stray debris.

Actionable Step: Use a soft, dry cloth specifically designed for electronics or a non-abrasive microfiber cloth. Gently wipe the entire surface of your hearing aids, paying close attention to the shell, microphone ports, and speaker outlets.
Concrete Example: After removing your Behind-The-Ear (BTE) hearing aids, hold the main unit in one hand and the earmold in the other. Use your cloth to wipe down the casing of the main unit, then carefully clean the surface of the earmold, ensuring no visible wax or oil remains. For In-The-Ear (ITE) or Completely-In-Canal (CIC) aids, gently wipe the entire outer surface.
Avoid: Harsh chemicals, alcohol wipes, or abrasive materials. These can damage the delicate coatings and electronic components. Never submerge your hearing aids in water or any cleaning solution.

Earwax Management: Your Hearing Aid’s Arch-Nemesis

Earwax is naturally produced by your ears, and while beneficial for ear health, it’s detrimental to hearing aid performance. It can block sound outlets, clog microphone ports, and even work its way into the internal circuitry, causing significant damage.

Actionable Step: Utilize the specific cleaning tools provided by your audiologist or hearing aid manufacturer, such as a wax pick, wire loop, or small brush.
Concrete Example (BTE with Earmold): Detach the earmold from the main hearing aid unit. Use the wax pick or wire loop to gently clear any visible earwax from the sound bore (the hole where sound exits) of the earmold. Then, use the small brush to remove any loose wax from the surface of the earmold and around the microphone openings on the main unit.
Concrete Example (RIC/RITE with Dome): Carefully remove the silicone dome. Use the cleaning brush to gently clear any wax or debris from the small grates or openings on the receiver (the part that sits in your ear canal). Inspect the dome for tears or excessive wax buildup; if heavily soiled or damaged, replace it.
Concrete Example (ITE/CIC): Use the small brush to meticulously sweep away any wax from the sound outlet and microphone openings. If your device has a wax guard, regularly inspect it. When you see a significant buildup of wax on the guard, follow your manufacturer’s instructions to replace it with a new one. This typically involves using a small tool to remove the old guard and insert a new one.
Frequency: Aim for daily earwax removal. If you produce a lot of earwax, consider cleaning multiple times a day.

Moisture Control: A Silent Destroyer

Moisture, whether from sweat, humidity, or accidental exposure, is a primary cause of hearing aid failure. It can corrode internal components, leading to static, intermittent sound, or complete device shutdown.

The Dehumidifier Difference: Investing in Dryness

A hearing aid dehumidifier or drying station is an invaluable investment, especially if you live in a humid climate, exercise frequently, or experience excessive sweating. These devices use desiccant materials or gentle heat to draw out moisture overnight.

Actionable Step: Place your hearing aids (with battery doors open for disposable batteries) in a hearing aid dehumidifier or drying jar every night.
Concrete Example: Before bed, open the battery compartment of your hearing aids, remove the batteries (if disposable), and place both the hearing aids and the batteries into the drying unit. For rechargeable aids, simply place them in their charging/drying station as instructed by the manufacturer. Ensure the unit is powered on (if electric) or the desiccant is active (if a drying jar).
Types of Dehumidifiers:
- Desiccant Drying Jars: These contain moisture-absorbing beads that change color when saturated, indicating they need to be replaced or regenerated (often by microwaving or baking). They are cost-effective and don’t require electricity.
- Electric Drying Stations: These often use gentle heat or a fan to circulate air and dry the hearing aids. Some also incorporate UV-C light for sanitation, though the primary benefit for longevity is moisture removal.
Importance: Even if your hearing aids are water-resistant, daily drying is crucial. “Water-resistant” does not mean “waterproof,” and prolonged exposure to moisture, even from perspiration, can cause damage.

Avoiding Moisture Hazards: Proactive Protection

Preventative measures are critical in the battle against moisture.

Actionable Step: Always remove your hearing aids before showering, bathing, swimming, or entering a sauna or steam room.
Concrete Example: Before stepping into the shower, habitually remove your hearing aids and place them in a designated dry, safe spot, like your bedside table or drying unit.
Actionable Step: If you use hairspray, perfume, or other aerosol products, apply them before putting on your hearing aids. The fine mist can clog microphone ports and damage sensitive electronics.
Concrete Example: Spray your hairspray, let it settle, and then put your hearing aids in. This small delay prevents sticky residue from coating your devices.
Actionable Step: Carry a small, soft, dry cloth with you to wipe away any visible moisture throughout the day, especially if you perspire heavily or are in a humid environment.
Concrete Example: If you’re gardening on a hot day and notice sweat on your ears, discreetly remove your hearing aids and give them a quick wipe-down before continuing.

Battery Care: The Lifeblood of Your Devices

Batteries power your hearing aids, and proper battery care directly impacts their performance and the overall health of the device.

Disposable Battery Best Practices: Maximize Each Cell

Most hearing aids use zinc-air disposable batteries, which are activated by air once the tab is removed.

Actionable Step: Store batteries in their original packaging at room temperature. Avoid refrigerators or freezers, as condensation can damage them.
Concrete Example: Keep your spare batteries in a cool, dry drawer, away from direct sunlight or extreme temperatures.
Actionable Step: Once you remove the tab to activate a battery, let it “air up” for about 1-2 minutes before inserting it into your hearing aid. This allows the air to fully activate the zinc-air chemistry, potentially extending its life.
Concrete Example: When a battery dies, peel the tab off a new one, place it on a clean surface, and let it sit for two minutes before putting it into your hearing aid.
Actionable Step: Open the battery doors of your hearing aids every night when not in use. This allows moisture to evaporate from the battery compartment and disconnects the battery, preventing unnecessary drain.
Concrete Example: Before placing your hearing aids in the drying unit at night, flip open the small battery door. This not only aids in drying but also ensures no power is being consumed.
Actionable Step: Always dispose of dead batteries responsibly. Do not leave dead batteries in your hearing aids, as they can leak and cause corrosive damage to the contacts.
Concrete Example: As soon as your hearing aid indicates a low battery or stops working, remove the old battery and place it in a designated battery recycling container.

Rechargeable Battery Maintenance: Consistent Charging for Longevity

Rechargeable hearing aids offer convenience, but proper charging habits are crucial for battery health.

Actionable Step: Charge your hearing aids fully every night. Avoid frequent partial charges, as this can degrade battery performance over time.
Concrete Example: Develop a habit of placing your rechargeable hearing aids in their charging case or dock every evening before bed, ensuring they are fully charged by morning.
Actionable Step: Keep the charging contacts on both the hearing aids and the charger clean.
Concrete Example: Periodically use a soft, dry cloth or a cotton swab to gently wipe the small metal contacts on your hearing aids and within the charging port of the charger.

Handling and Storage: Protection from Physical Harm

Accidental drops, crushing, and improper storage are common causes of physical damage to hearing aids.

Gentle Handling: Treat Them with Care

Hearing aids contain delicate micro-electronics. Rough handling can lead to internal damage that’s not always visible.

Actionable Step: Always insert and remove your hearing aids over a soft surface, like a towel or a bed. This minimizes the impact if they accidentally slip from your fingers.
Concrete Example: When putting on your hearing aids in the morning, sit over your bed or a thick bath towel. If a hearing aid drops, it will land on a cushioned surface.
Actionable Step: Avoid dropping your hearing aids into pockets or bags where they can be crushed or come into contact with keys, coins, or other abrasive objects.
Concrete Example: If you need to temporarily remove your hearing aids while out, place them in a hard, protective carrying case, not loosely in your purse or pants pocket.

Secure Storage: A Safe Haven

When not in use, your hearing aids need a designated safe space.

Actionable Step: Store your hearing aids in their charging unit, drying station, or a hard carrying case when not in use.
Concrete Example: At night, after cleaning and drying, always place your hearing aids back into their designated drying unit or protective case on your bedside table.
Actionable Step: Keep hearing aids out of reach of children and pets. Dogs, in particular, are attracted to the smell of earwax and can chew on hearing aids, causing irreparable damage.
Concrete Example: Never leave your hearing aids on a low coffee table or on the floor. Store them in a high cabinet or a securely closed drawer.
Actionable Step: Avoid storing hearing aids in extreme temperatures, such as in a hot car, near a radiator, or in direct sunlight. Heat can warp plastic components and damage electronics.
Concrete Example: On a hot day, if you need to take your hearing aids out in the car, place them in their protective case and put them in a cooler, shaded spot, not on the dashboard or in a glove compartment.
