Hearing aids are precision instruments that work hard every day—and they need regular attention to perform well and last as long as they should. Proper care isn't complicated, but it does matter. The habits you develop now can extend the life of your devices, prevent costly repairs, and help you get the best sound quality possible.
Hearing aids sit in or near your ears, where they're exposed to moisture, earwax, and temperature changes. Unlike eyeglasses or phones, they work in a uniquely challenging environment. Daily maintenance prevents buildup that can damage the microphones and speakers, reduce battery life, and muffle sound. The investment in a few simple routines often pays for itself in avoided repairs and replacements.
Wipe the outside casing with a clean, dry cloth each evening. This removes earwax, oils, and moisture that accumulate throughout the day. Use a soft, lint-free material—the kind sold specifically for hearing aids, or a regular eyeglass cloth works fine.
Clean the earpiece or dome where sound enters your ear canal. Earwax naturally collects here and can block sound output or damage the receiver. Many hearing aids come with a small brush or cleaning pick for this purpose. Gently brush away visible debris. For in-the-ear (ITE) or completely-in-the-canal (CIC) models, spend extra attention here, as they sit deeper in the ear canal where earwax accumulation is heavier.
Never use water, alcohol, or liquid cleaners on the device itself unless your audiologist specifically advises it. These can damage the electronics and the battery compartment.
Moisture is one of the biggest threats to hearing aid longevity. Your ears naturally produce moisture, and humid environments add to the problem. Several strategies help:
Use a hearing aid dehumidifier overnight. These devices (sometimes called dry-aid kits) come in two types: electric versions that warm and dry your aids, or passive units with absorbent pellets that you replace periodically. Dehumidifiers are especially important if you live in a humid climate, exercise regularly, or tend to sweat.
Store aids in the dehumidifier with the battery compartment open so air can circulate inside.
Avoid bathrooms right after showers. The steam can damage electronics. If you shower while wearing aids (some are water-resistant for this), pat them dry immediately afterward.
Don't expose aids to direct heat. Your car, radiator, or hair dryer can warp components and damage the battery.
Your hearing aid batteries power everything, so treating them well matters:
Keep tabs on expiration dates printed on battery packages. Old batteries may perform inconsistently.
Remove the plastic tab before inserting a new battery—this activates the battery, not the moment you close the compartment.
Leave the battery door open overnight when your aids are in storage. This lets moisture escape and prolongs battery shelf life.
Store batteries in a cool, dry place—not in the bathroom or car. Temperature extremes reduce performance.
Don't mix old and new batteries in the same device, and avoid mixing different brands when possible. This reduces unpredictable performance.
The lifespan of a battery depends on the size, your hearing aid model, and how many hours daily you wear them. Most last between 3 and 10 days, though individual experience varies significantly.
| Task | Frequency | Why |
|---|---|---|
| Wipe exterior | Daily | Removes earwax and moisture |
| Clean earpiece/dome | Daily | Prevents sound blockage |
| Open battery door | Nightly | Allows internal moisture to escape |
| Replace wax filter (if applicable) | Every 1–2 weeks or as needed | Keeps receiver clear |
| Full dehumidification | Nightly | Protects electronics |
| Professional cleaning | Every 3–6 months | Removes buildup audiologist tools can address |
Some maintenance tasks require an audiologist's equipment and expertise:
Your audiologist can show you which tasks you can safely do at home and which are best left to them. Most recommend a professional cleaning and inspection every 3 to 6 months, depending on earwax production and environmental factors.
Keep aids away from pets. Dogs and cats are curious—losing a hearing aid to a pet is more common than you'd expect.
Remove aids before applying hair products, lotions, or makeup. Sprays and oils can coat the microphone and affect sound quality.
Take them out before swimming or showering unless they're specifically rated water-resistant (different from waterproof—check your model's specifications).
Store in a protective case when not wearing them, especially if you're traveling or in dusty environments.
Be mindful in very cold weather. Extreme cold can temporarily reduce battery performance, though batteries typically rebound as they warm.
Your specific maintenance needs depend on several factors:
Your hearing aid type (behind-the-ear, in-the-ear, receiver-in-canal, etc.)—models differ in how much earwax exposure they have and how water-resistant they are.
Your earwax production. Some people naturally produce more cerumen; if this is you, more frequent cleaning prevents blockages.
Your environment. Humid climates, jobs involving dust or sweat, or very active lifestyles all increase the importance of moisture management.
Your hearing aid features. Advanced features sometimes require gentler handling or specialized care during cleaning.
Your audiologist knows your device and can tailor a care plan that matches your situation, habits, and the specific risks you face.
Hearing aid care is straightforward: keep them clean and dry, manage moisture actively, handle batteries properly, and work with your audiologist on tasks that need professional tools. The time investment is minimal, but the payoff—clear sound, fewer repairs, and longer device life—is substantial.
