Learn About Cleaning Your Hearing Aids

Understanding Your Hearing Aid Components and Their Function

Hearing aids consist of several key parts that work together to amplify sound and deliver it to your ear. The microphone picks up sounds from your environment, while the amplifier increases the volume of those sounds. The receiver (also called a speaker) then sends the amplified sound into your ear canal. A battery or rechargeable power source provides energy to run these components. The casing, typically made of plastic or acrylic, holds all these parts together and sits either behind your ear or inside your ear canal, depending on the style.

The tubing and earmold in behind-the-ear (BTE) hearing aids direct sound from the device into your ear. In-the-ear (ITE) models place all components directly in the ear canal. Understanding these parts matters because each one can accumulate earwax, moisture, and debris that affects performance. The microphone openings are particularly vulnerable to blockage. When you know where these sensitive areas are located on your specific model, you can clean more effectively without causing damage.

Different hearing aid styles require slightly different cleaning approaches. Behind-the-ear aids have exposed tubing that can become cracked or clogged. In-the-ear models have smaller spaces where moisture builds up more quickly. Completely-in-canal (CIC) hearing aids sit deep in the ear and are more prone to earwax accumulation. Receiver-in-canal (RIC) devices have thin wires instead of tubing, which can tangle or break. Your hearing aid manual will specify which cleaning methods and tools are safe for your particular model.

Practical takeaway: Locate your hearing aid's microphone openings, receiver, battery compartment, and tubing (if applicable). Refer to your device manual to identify which parts are most prone to moisture and debris buildup specific to your model. This knowledge guides where you should focus your cleaning efforts.

Daily Cleaning Procedures and Tools You'll Need

Daily cleaning keeps your hearing aids functioning well and extends their lifespan. You'll need a few basic tools: a soft, dry cloth or microfiber cloth designed for hearing aids, a cleaning brush or wax pick (usually included with your devices), and possibly a wax guard or filter if your model uses replaceable ones. Do not use water, alcohol, or chemical solvents during daily cleaning, as these can damage the internal electronics and the exterior casing. Some people also use compressed air, but this should be done carefully and only if your manual recommends it.

Start your daily cleaning in the morning after you remove your hearing aids. Wipe the exterior with a dry cloth, paying attention to any visible debris or dried earwax. Use the cleaning brush or wax pick to gently remove debris from the microphone openings and receiver area. Make small, gentle circular motions rather than scraping forcefully. If your hearing aid has a wax guard or filter, inspect it for buildup and replace it if it appears clogged or discolored. Many wax guards can be replaced without professional tools.

For behind-the-ear models with tubing, check the tubing for moisture inside. You may see condensation or cloudiness in clear tubing. If the tubing feels stiff or cracked, it needs replacement. Some tubing can be gently cleared by using the pipe cleaner tool often provided in cleaning kits, but never force it. If the tubing is damaged, contact your hearing aid provider for a replacement. The earmold can be wiped with a dry cloth but should not be submerged in water unless your manual explicitly states that the earmold alone is waterproof (the hearing aid itself is not).

Inspect your battery compartment daily. Wipe the battery contacts with a dry cloth if they appear corroded or dirty. Battery corrosion looks like white, blue, or green deposits on the metal contacts. If you see this, gently rub the contacts and the battery terminals with a clean, dry cloth. Always allow new batteries to sit for several minutes after removing the plastic tab before inserting them into the device, as this activates the battery's full power.

Practical takeaway: Create a morning routine: wipe your hearing aids with a dry cloth, check the microphone and receiver areas with your brush, inspect the wax guard or filter, and check for tubing condensation. This 3-5 minute daily habit prevents major problems from developing.

Handling Moisture, Humidity, and Sweat Buildup

Moisture is one of the biggest threats to hearing aid longevity. Earwax is naturally moist, and your ear canal produces humidity throughout the day. Sweat from physical activity, warm weather, or stress can accelerate moisture accumulation inside your devices. Hearing aids are not waterproof, though many models are water-resistant to varying degrees. Water resistance ratings indicate how much moisture exposure a device can tolerate, but these devices still require active moisture management on your part.

After you remove your hearing aids each day, store them in a dry location. Ideally, place them in a hearing aid dehumidifier or drying container. These devices come in several types: electric dehumidifiers that use gentle heat, desiccant boxes that use silica gel or other absorbing materials, or UV sanitizers that combine drying with disinfection. Many people use a simple desiccant container as a backup even if they have an electric dehumidifier. The desiccant material needs replacement according to the product instructions, typically when the color indicator shows saturation.

If you experience heavy sweating due to exercise, warm climates, or humidity, consider additional protective measures. Some people use hearing aid sweatbands or protective covers during workouts. These are fabric or plastic barriers that reduce direct moisture contact. After sweating, remove the covers and allow your hearing aids to dry before reinserting them. Never store your hearing aids in a closed case while they're still moist, as this creates an environment where moisture becomes trapped and mold can develop.

In humid climates, your nightly drying routine becomes even more important. Some people leave their hearing aids in the dehumidifier overnight every single night, while others do this three to five times per week depending on climate and activity level. If you notice condensation inside the tubing of a behind-the-ear hearing aid, this indicates excess moisture. Gently remove the earmold from the tubing and use a dry cloth or pipe cleaner to absorb moisture from inside the tube. Leave the components separated to dry for several hours or overnight.

Watch for signs of moisture damage: sound cutting in and out, reduced volume, crackling noises, or the hearing aid shutting off unexpectedly. These often indicate moisture has reached the internal components. If this happens, open the battery compartment completely and store the device in a dehumidifier for 24-48 hours. Sometimes this resolves the issue. If problems persist after drying, contact your hearing aid provider for professional assessment.

Practical takeaway: Invest in a desiccant box or dehumidifier and use it every night. If you live in a humid climate, exercise regularly, or experience frequent sweating, use it nightly without exception. This single practice extends hearing aid life significantly and prevents the majority of moisture-related problems.

Cleaning the Earmold, Tubing, and Receiver Components

Earmolds (the part that sits in your ear canal) accumulate earwax, skin cells, and debris over time. Earwax buildup not only reduces sound quality but can also prevent sound from reaching your ear properly. You can clean the earmold by holding it under lukewarm running water and gently rubbing away visible debris with your fingers or a soft cloth. Never soak the earmold while it's attached to the hearing aid itself, and never use hot water, which can warp the acrylic or silicone material.

After rinsing the earmold, dry it completely with a soft cloth before reattaching it to the hearing aid. Check the small hole inside the earmold where sound passes through—this opening should be clear and unobstructed. If you see earwax inside this opening, use the wax pick or cleaning wire to gently remove it. Be very careful not to push debris deeper into the opening. Some people find that soaking the earmold in warm water for 5-10 minutes first softens the earwax, making it easier to remove. If earwax is extremely impacted, your hearing aid provider can perform professional cleaning.
