Your hearing aids are small, sophisticated devices doing a big job. They sit in one of the most demanding environments imaginable — inside your ear — exposed to warmth, moisture, earwax, and constant movement from sunrise to bedtime. The good news? A few consistent habits go a long way toward protecting your investment and keeping your hearing crisp and clear.
At San Antonio Custom Hearing, we work with patients across the Greater San Antonio Metro and Schertz, TX who want to get the most out of their devices. Here's what we recommend.
Build a Daily Cleaning Routine
Consistency is the foundation of hearing aid longevity. Debris builds up faster than most people realize, and even a small accumulation of earwax or dust can muffle sound or stress the internal components.
Wipe Them Down Every Night
Before setting your hearing aids aside for the night, take 30 seconds to wipe them down with a soft, dry cloth. This removes surface oils, moisture, and light debris before anything has a chance to harden or work its way into the device.
Avoid using water, alcohol wipes, or household cleaning sprays — these can damage the delicate electronics and void your warranty.
Use a Hearing Aid Brush for Stubborn Debris
Most hearing aids come with a small cleaning brush designed specifically for the job. Use it to gently clear the microphone ports, speaker openings, and any crevices where debris tends to collect. If your device uses a dome or earmold, clean those separately with a dry cloth or an approved earmold spray.
Protect Your Devices from Moisture
Humidity is one of the most common — and most overlooked — causes of hearing aid damage. Even if you never submerge your devices in water, the everyday moisture from sweat, rain, and bathroom steam adds up.
Consider a Hearing Aid Dehumidifier
A dehumidifier designed for hearing aids is one of the smartest small investments you can make. Place your devices inside overnight, and the unit quietly draws out trapped moisture while you sleep. This is especially valuable during San Antonio's hot, humid summers.
Store Them Smart
When you're not wearing your hearing aids, keep them in a protective case in a cool, dry location. Nightstands and dresser tops work well. Bathrooms do not — the steam from showers creates exactly the kind of environment your devices need to avoid. Avoid leaving them in a parked car, where temperatures can spike quickly and cause internal damage.
Stay on Top of Battery Health
A weak battery affects everything — sound clarity, connectivity, and overall device performance. Whether your hearing aids use disposable batteries or a rechargeable system, a little attention goes a long way.
Disposable Battery Tips
- Wash and dry your hands before handling batteries to keep moisture and oils away from the contacts.
- Store spare batteries at room temperature, away from humid or hot environments.
- If you won't be wearing your hearing aids for several days, remove the batteries to prevent corrosion.
- Fading volume or intermittent sound is usually the first sign a battery is running low — keep spares nearby.
Rechargeable Systems
If your devices are rechargeable, follow the manufacturer's guidance on charging cycles. Placing them in their charging case each night builds a reliable routine and ensures you start every morning with a full charge.
Manage Earwax Buildup
Earwax is natural, but it's also the number-one reason hearing aids underperform. It migrates into sound ports and wax filters, gradually reducing sound output in ways that are easy to mistake for a dead battery or a bigger problem.
Most devices include a wax pick or loop tool for clearing the speaker port. Use it regularly and gently. Many hearing aids also use replaceable wax filters — swapping these out on a routine basis takes about a minute and makes a noticeable difference in sound clarity. Your audiologist can show you exactly how to do this for your specific model.
Handle with Care
Hearing aids are built to be durable, but they're not indestructible. Repeated drops onto tile, hardwood, or concrete can shift internal components and crack the casing in ways that shorten the device's life.
A few smart habits:
- Remove and insert your hearing aids while sitting over a soft surface, like a bed or a carpeted area.
- Keep them in their case any time they're not in your ears.
- Take them out before applying hairspray, sunscreen, or other aerosol products.
Schedule Regular Professional Checkups
Even the most diligent at-home care has limits. Professional maintenance goes deeper — cleaning internal components, checking for wear, testing performance, and making fine adjustments that keep your devices performing the way they should.
Our clinical team at San Antonio Custom Hearing catches issues early, before they become costly repairs. We also make sure your devices are still properly fitted to your hearing profile, because your hearing needs can shift over time.
If you haven't had your hearing aids professionally serviced in the past six months, it's a good time to schedule a visit. Patients across Schertz and the Greater San Antonio area can reach us directly to book a maintenance appointment — no referral needed.
Small Habits, Big Results
Hearing aid care doesn't require a complicated regimen. A nightly wipe-down, smart storage, clean batteries, and a professional checkup every few months will protect your investment and keep your hearing clear for years to come.
Your hearing aids are doing important work. Treat them accordingly — and they'll treat you well in return.
