The Definitive Guide to Cleaning Your Hearing Aids: Preserving Your Hearing Health

Your hearing aids are more than just electronic devices; they are a vital link to the world of sound, connecting you with conversations, music, and the subtle nuances of your environment. Just like any sophisticated instrument, they require regular care and meticulous cleaning to perform optimally and ensure their longevity. Neglecting this crucial aspect of hearing aid ownership can lead to reduced sound quality, frequent repairs, and even potential ear infections. This comprehensive guide will equip you with the knowledge and actionable steps needed to maintain your hearing aids in pristine condition, safeguarding your hearing health and maximizing your investment.

Why Regular Hearing Aid Cleaning is Non-Negotiable

Before diving into the “how-to,” let’s understand the “why.” Your ears produce earwax (cerumen), a natural substance designed to protect and lubricate the ear canal. While beneficial in moderation, earwax, along with skin cells, dust, and moisture, can accumulate on and inside your hearing aids. This buildup creates a breeding ground for bacteria and can significantly impede sound transmission.

Consider these compelling reasons for a consistent cleaning regimen:

• Optimal Sound Quality: Even a thin film of earwax can muffle sound, making voices unclear and music distorted. Regular cleaning ensures unimpeded sound delivery, allowing you to experience the full benefit of your hearing aids. Imagine trying to listen to your favorite song with a blanket over the speaker – that’s what a dirty hearing aid can do to your listening experience.

• Prevention of Costly Repairs: Earwax and moisture are the primary culprits behind hearing aid malfunctions. Blocked microphone ports, clogged receivers, and corroded battery contacts are common issues directly linked to insufficient cleaning. Proactive cleaning can significantly reduce the frequency and cost of professional repairs. Think of it like changing the oil in your car; it’s a small investment that prevents a much larger breakdown.

• Extended Lifespan of Your Devices: Hearing aids are a significant financial investment. By preventing damage from earwax and moisture, you extend their operational lifespan, maximizing your return on that investment. A well-maintained hearing aid can last several years longer than one that is neglected.

• Enhanced Hygiene and Reduced Risk of Infection: Your hearing aids sit directly in your ear canal for extended periods. Without proper cleaning, they can harbor bacteria and fungi, increasing your risk of ear infections. This is particularly important for individuals prone to swimmer’s ear or other ear-related issues. Picture wearing the same unwashed clothes for days on end – the principle of hygiene applies just as strongly to your hearing aids.

• Improved Comfort: Buildup on your hearing aids can make them feel uncomfortable or itchy in your ear. A clean device not only sounds better but also feels better, promoting greater compliance with consistent wear. A smooth, clean surface is less likely to irritate your delicate ear canal.

• Reliable Performance in All Environments: From a humid day to a dusty room, your hearing aids are exposed to various environmental factors. Regular cleaning removes these contaminants, ensuring reliable performance regardless of your surroundings. You wouldn’t expect a dusty camera lens to take clear photos; similarly, a dirty hearing aid won’t deliver clear sound.

Essential Tools for Hearing Aid Cleaning

Before you begin, gather the necessary tools. Having these readily available will make your cleaning routine efficient and effective. Avoid using harsh chemicals, alcohol, or abrasive materials, as these can damage your delicate devices.

Here’s your cleaning toolkit:

• Soft, Dry Cloth: A microfiber cloth is ideal, as it’s lint-free and gentle. This will be your primary tool for wiping down the external surfaces of your hearing aids.

• Wax Pick/Brush: Most hearing aid manufacturers provide a small tool with a brush on one end and a small wire loop or pick on the other. This is indispensable for removing stubborn wax and debris from small openings. If you don’t have one, ask your audiologist.

• Vent Cleaner (for custom molds/ITE/ITC aids): A thin wire loop or a specialized vent pick is used to clear the tiny vent hole in custom earmolds or in-the-ear (ITE) and in-the-canal (ITC) hearing aids.

• Battery Door Brush (optional): Some cleaning kits include a tiny brush specifically for cleaning around the battery door and contacts.

• Hearing Aid Drying Kit/Dehumidifier: This is arguably one of the most important investments for hearing aid longevity. These kits come in various forms, from simple desiccant capsules to electronic dehumidifiers. They remove moisture that can corrode internal components.

• Soft Bristle Toothbrush (new and dedicated): For more stubborn debris on certain external parts (like the shell of a BTE), a soft-bristle toothbrush can be effective, but ensure it’s new and used only for your hearing aids.

• Mild, Non-Alcoholic Wipes (specifically for hearing aids): Some manufacturers offer pre-moistened wipes designed for hearing aids. These are convenient for quick sanitization, but always check compatibility with your specific device. Avoid household cleaning wipes.

Step-by-Step Cleaning Guide for Behind-the-Ear (BTE) Hearing Aids

BTE hearing aids consist of a main unit that rests behind the ear and an earmold or dome that sits in the ear canal, connected by a thin tube. Each component requires specific cleaning attention.

Daily Cleaning (Every Evening):

1. Wash and Dry Your Hands: Always start with clean, dry hands to avoid transferring dirt or moisture to your hearing aids.

2. Remove from Ear: Carefully remove your BTE hearing aid from your ear.

3. Wipe Down the Main Unit: Using your soft, dry cloth, gently wipe down the entire main unit that sits behind your ear. Pay attention to the surfaces, control buttons, and the area around the battery door. This removes any skin oils, dust, and light debris.

   • Example: Imagine wiping fingerprints off a smartphone screen. You’re aiming for a clean, non-greasy surface.
4. Inspect and Wipe the Earmold/Dome and Tubing: Carefully inspect the earmold or dome that sits in your ear canal. Wipe it thoroughly with your dry cloth, removing any visible earwax or debris. Also, wipe the tubing connecting the main unit to the earmold/dome.
   • Example: If you see a small accumulation of wax on the dome, gently flick it off with your finger or use the soft brush.
5. Brush the Microphone Port: Locate the tiny microphone port(s) on the main unit. Use the brush end of your wax pick to gently brush away any debris that might be blocking them. Be very gentle; these are delicate.
   • Example: Think of a tiny, almost invisible hole. You’re clearing out any dust specks that might be obstructing it, similar to blowing dust off a camera lens.
6. Place in Drying Kit: Once wiped clean, place your BTE hearing aid in your drying kit or dehumidifier overnight. This is crucial for removing any accumulated moisture.
   • Example: If you use desiccant capsules, ensure they are fresh and the container is sealed. For electronic dryers, simply place the aids inside and close the lid.

Weekly/Bi-Weekly Deep Cleaning (for BTE Earmolds – Detachable):

If your BTE hearing aid has a detachable earmold, you can perform a more thorough cleaning of the earmold itself. Never immerse the main hearing aid unit in water.

1. Detach the Earmold: Gently disconnect the earmold from the tubing of the main BTE unit.
   • Example: Most earmolds simply pull off the end of the tubing with a firm but gentle tug.
2. Remove Visible Wax: Use your wax pick or the wire loop to carefully remove any visible earwax from the earmold, especially from the sound bore (the hole where sound comes out) and the vent.
   • Example: If you see a clump of wax inside the sound bore, use the loop of the wax pick to scoop it out. Gently work it free without pushing it further in.
3. Wash the Earmold: Fill a small bowl with lukewarm (not hot!) soapy water using a mild dish soap (a single drop is sufficient). Place the detached earmold in the water and let it soak for a few minutes.
   • Example: Think of washing a delicate piece of jewelry. You want enough water to cover the earmold, and just a hint of soap to break down oils.
4. Brush and Rinse: Using a soft toothbrush (dedicated for this purpose), gently brush all surfaces of the earmold, paying close attention to the sound bore and the vent. Rinse the earmold thoroughly under cool, running water to remove all soap residue.
   • Example: Hold the earmold under a gentle stream from the faucet, ensuring water flows through the sound bore and vent.
5. Dry Thoroughly: This is critical. Shake the earmold vigorously to remove excess water. Use an ear bulb blower (a small rubber bulb that creates a puff of air) to force air through the sound bore and vent to ensure all water droplets are expelled. You can also use a small, soft cloth to pat it dry. Let it air dry completely for several hours, ideally overnight, before reattaching it to the hearing aid.
   • Example: After blowing air through, hold the earmold up to a light and visually inspect for any lingering water droplets inside the tubes. You should see no condensation.
6. Reattach the Earmold: Once completely dry, carefully reattach the earmold to the tubing of the main BTE unit. Ensure a secure connection.

Step-by-Step Cleaning Guide for In-The-Ear (ITE) and In-The-Canal (ITC) Hearing Aids

ITE and ITC hearing aids are custom-molded to fit entirely or mostly within the ear canal. Due to their placement, they are more susceptible to earwax buildup.

Daily Cleaning (Every Evening):

1. Wash and Dry Your Hands: As always, start with clean, dry hands.

2. Remove from Ear: Carefully remove your ITE/ITC hearing aid from your ear.

3. Wipe Down the Entire Surface: Use your soft, dry cloth to gently wipe down the entire outer surface of the hearing aid. This removes oils, dust, and light debris.

   • Example: Imagine gently wiping the outside of a small pebble. You want to remove any visible smudges.
4. Clean the Microphone Port(s): Locate the tiny microphone port(s). Use the brush end of your wax pick to gently brush away any debris.
   • Example: These ports are typically very small, sometimes just pinholes. Gently sweep the brush across them.
5. Clean the Sound Bore/Receiver Opening: This is the most crucial part for ITE/ITC aids. This is where sound exits the hearing aid and enters your ear. Earwax frequently accumulates here. Use the wire loop or pick end of your wax tool to carefully scoop out any visible earwax. Always angle the pick so that you pull wax out of the opening, rather than pushing it further in.
   • Example: Think of scooping out a tiny amount of jam from a small jar. Go slowly and gently, pulling the wax outwards. If there’s a wax guard, proceed to step 6.
6. Inspect and Clean the Vent (if applicable): Many ITE/ITC aids have a small vent hole. Use a specialized vent cleaner or a thin wire loop to carefully clear any wax or debris from this vent. Gently push the cleaner all the way through the vent to ensure it’s completely clear.
   • Example: If the vent is blocked, it can affect sound quality and even cause an “occlusion effect” (your own voice sounding too loud or boomy).
7. Place in Drying Kit: Once cleaned, place your ITE/ITC hearing aid in your drying kit or dehumidifier overnight.

Weekly/Bi-Weekly Deep Cleaning (for ITE/ITC Hearing Aids – Wax Guards):

Many ITE/ITC (and some RIC) hearing aids feature disposable wax guards (also called wax filters or cerumen filters). These are small, replaceable screens that protect the receiver (speaker) from earwax. You should replace them regularly as part of your deeper cleaning routine, or whenever you notice sound becoming muffled despite daily cleaning.

1. Identify Your Wax Guard Type: There are several types of wax guards (e.g., CeruShield, ProWax, HF4, HF3). Your audiologist can show you how to identify and replace yours. Your hearing aid usually comes with a small tool for replacement.

2. Remove the Old Wax Guard: Your wax guard tool typically has two ends: one with a new wax guard attached and one with a hook or empty slot to remove the old one. Insert the empty end into the old wax guard and pull it straight out.

   • Example: It’s like pulling a tiny stopper out of a bottle.
3. Insert the New Wax Guard: Flip the tool over and insert the new wax guard firmly into the opening where the old one was removed. It should click or seat securely into place.
   • Example: Ensure it’s flush with the surface of the hearing aid, not protruding.
4. Discard Old Wax Guard: Dispose of the old wax guard properly.

• Note: Some ITE/ITC hearing aids, particularly older models, may not have replaceable wax guards but rather a mesh screen that requires careful brushing. Consult your audiologist if you are unsure.

Step-by-Step Cleaning Guide for Receiver-In-Canal (RIC) / Receiver-In-Ear (RIE) Hearing Aids

RIC/RIE hearing aids are a hybrid, with the main unit behind the ear and a thin wire leading to a small receiver (speaker) that sits inside the ear canal. The receiver end often has a dome or a custom-made mold.

Daily Cleaning (Every Evening):

1. Wash and Dry Your Hands: Always start with clean, dry hands.

2. Remove from Ear: Carefully remove your RIC/RIE hearing aid.

3. Wipe Down the Main Unit: Use your soft, dry cloth to gently wipe down the main unit that sits behind your ear, including control buttons and the area around the battery door.

4. Inspect and Wipe the Receiver and Wire: Carefully inspect the receiver (the part that goes into your ear) and the thin wire connecting it to the main unit. Wipe them thoroughly with your dry cloth, removing any visible earwax or debris.

   • Example: Run the cloth along the wire to remove any skin oils or dust.
5. Clean the Microphone Port: Locate the tiny microphone port(s) on the main unit. Use the brush end of your wax pick to gently brush away any debris.

6. Inspect and Clean the Dome/Earmold: If your RIC uses a dome (a small, disposable silicone tip), gently wipe it down. If it’s heavily soiled or stiff, consider replacing it (see below). If it uses a custom earmold, follow the steps for cleaning BTE earmolds, but do not detach it from the receiver wire unless instructed by your audiologist, as this can damage the delicate connection. Instead, clean the outside of the earmold carefully with the soft cloth and brush the sound bore.

   • Example: If your dome is starting to look discolored or feels sticky, it’s time for a replacement.
7. Place in Drying Kit: Once wiped clean, place your RIC/RIE hearing aid in your drying kit or dehumidifier overnight.

Weekly/Bi-Weekly Deep Cleaning (for RIC Domes and Wax Guards):

RIC hearing aids commonly use disposable domes and often have replaceable wax guards on the receiver itself.

1. Replace Domes (as needed): Domes are designed to be replaced regularly – typically every 2-4 weeks, or sooner if they appear soiled, torn, or stiff. Gently pull the old dome off the receiver. Push a new, clean dome firmly onto the receiver until it clicks or seats securely.
   • Example: If your dome looks flattened or has visible tears, replace it immediately. You’ll typically get a supply of domes from your audiologist.
2. Replace Wax Guards: Like ITE/ITC aids, many RIC receivers have replaceable wax guards. Follow the same procedure outlined for ITE/ITC wax guard replacement, using your specific wax guard tool. The wax guard is typically located at the very end of the receiver, where the dome attaches.
   • Example: If you experience a sudden decrease in sound or muffled sound, the first thing to check after cleaning is the wax guard. Replacing it often resolves the issue instantly.

Advanced Care and Troubleshooting Tips

Beyond the daily and weekly routines, incorporating these advanced tips can further extend the life and performance of your hearing aids.

• Avoid Moisture at All Costs: Water and electronics do not mix.
  • Remove Before Showering/Bathing/Swimming: This is non-negotiable. Always remove your hearing aids before engaging in any water-related activities.

  • Remove Before Hair Styling/Hair Spray/Perfume: The fine mist from these products can clog microphone ports and damage components. Apply these products before inserting your hearing aids.

  • Wipe Away Sweat Immediately: If you perspire heavily, gently wipe down your hearing aids as soon as possible. Consider using a drying kit more frequently.

• Handle with Care: Your hearing aids are delicate instruments.

  • Always Hold Over a Soft Surface: When changing batteries or cleaning, always work over a soft towel or cloth. This prevents damage if you accidentally drop them.

  • Avoid Drops and Impacts: Dropping your hearing aids, even from a short height, can cause internal damage.

• Battery Care:

  • Open Battery Doors at Night: When not in use (e.g., overnight), open the battery door completely. This helps moisture evaporate and extends battery life by disengaging the power.

  • Store Batteries Properly: Keep fresh batteries in a cool, dry place, away from extreme temperatures and metal objects that could short-circuit them.

  • Dispose of Old Batteries Responsibly: Follow local regulations for battery disposal.

• Protect from Extreme Temperatures:

  • Avoid Direct Sunlight: Do not leave your hearing aids on dashboards, windowsills, or near heat sources where they can be exposed to direct sunlight or extreme heat. This can warp plastic components and damage internal electronics.

  • Protect from Extreme Cold: While less damaging than heat, extreme cold can affect battery performance.

• Professional Cleaning and Maintenance:

  • Regular Audiologist Visits: Schedule regular check-ups with your audiologist (typically every 6-12 months). They have specialized tools and expertise to perform a deeper clean, check for internal issues, and make any necessary adjustments or repairs. They can also provide fresh supplies like domes and wax guards.

  • Don’t Attempt Internal Repairs: Never try to open your hearing aid casing or attempt internal repairs yourself. This will void your warranty and likely cause irreversible damage.

• Travel Care:

  • Use a Protective Case: Always store your hearing aids in their protective case when traveling.

  • Pack Your Cleaning Kit: Don’t forget your essential cleaning tools and drying kit when you travel.

• Signs Your Hearing Aids Need Attention (Beyond Cleaning):

  • Muffled or Distorted Sound: If cleaning doesn’t resolve this, it might be a deeper issue (e.g., a failing receiver).

  • Intermittent Sound: Sound cutting in and out could indicate a loose connection or battery issue.

  • No Sound: Check the battery first, then the wax guard. If still no sound, contact your audiologist.

  • Whistling or Feedback: While sometimes caused by an improper fit, persistent feedback could also indicate a crack in the tubing (for BTEs) or an issue with the microphone.

  • Physical Damage: Any cracks in the casing, frayed wires, or missing parts require professional attention.

Debunking Common Hearing Aid Cleaning Myths

There’s a lot of misinformation out there about hearing aid care. Let’s set the record straight:

• Myth: You can clean hearing aids with rubbing alcohol or hydrogen peroxide.
  • Reality: Absolutely NOT. Alcohol and peroxide can dry out and crack plastic components, corrode metal parts, and damage delicate internal electronics. Stick to the recommended cleaning solutions and tools.
• Myth: Cotton swabs are good for cleaning inside the ear or hearing aid vents.
  • Reality: While cotton swabs can wipe external surfaces, they are notorious for pushing earwax further into the ear canal or into the small openings of your hearing aid, creating deeper blockages. Use only the specialized wax pick/brush and vent cleaner.
• Myth: Rice is a good substitute for a hearing aid dryer.
  • Reality: While rice can absorb some moisture, it’s not as effective as a dedicated drying kit/dehumidifier. Furthermore, tiny dust particles from rice can actually get inside your hearing aid and cause damage. Invest in a proper dryer.
• Myth: You only need to clean your hearing aids when they stop working.
  • Reality: This is a reactive approach that leads to preventable issues. Proactive, daily cleaning prevents most problems from occurring in the first place, ensuring consistent performance and extending lifespan.
• Myth: All hearing aids are cleaned the same way.
  • Reality: As this guide demonstrates, cleaning methods vary significantly depending on the type of hearing aid (BTE, ITE, RIC). Always follow the specific instructions for your device.
