Your hearing aids represent a significant investment in your quality of life—neglecting maintenance can shorten their lifespan and degrade sound quality within months. Proper daily care takes just five minutes and prevents expensive repairs that can cost $200–$500 per device. This guide walks you through the cleaning routines and protective habits that keep your hearing aids performing at peak levels.
Why Daily Maintenance Matters
Hearing aids operate in a hostile environment: your ear canal produces cerumen (earwax), moisture from sweat and humidity, and dead skin cells that accumulate on microphones and receivers. Over time, this buildup causes feedback, reduced volume, or complete device failure. Manufacturers like Widex, Phonak, and Oticon design devices to withstand normal use, but they all require consistent care to maintain warranties and optimal function.
Daily Cleaning Routine
Start each morning or evening by inspecting your hearing aids under good lighting. Use a soft, dry cloth—the kind included in most hearing aid kits—to wipe the exterior casing and earmold. Pay special attention to the receiver (speaker end) and the microphone openings on top of the device.
For earwax removal, use the small brush or wax pick that came with your hearing aids. Gently brush away any visible debris from the receiver opening. Never use water or liquids at this stage; moisture is the enemy of circuitry. If earwax is impacted or stubborn, schedule a 15-minute appointment with your audiologist—they have specialized tools to remove it safely without damaging the speaker.
Custom earmolds should be cleaned separately with a damp cloth and dried completely before reattaching. If your molds are severely yellowed or discolored, replacement typically costs $100–$250 per pair and can be ordered through your provider.
Moisture Management
Humidity and sweat are the leading causes of hearing aid malfunction. If you live in a humid climate or exercise regularly, invest in a hearing aid dehumidifier (also called a drying box), which costs $30–$80 and uses silica gel or electronic drying cycles to pull moisture from your devices overnight. Replace silica gel packets monthly or when they turn pink—a clear sign they're saturated.
Never wear hearing aids while showering, swimming, or in the rain. Even if your model carries an IPX rating (water resistance), this rating doesn't mean complete waterproof protection—it means it can survive brief water exposure, not prolonged immersion.
Battery and Storage
Hearing aid batteries typically last 3–10 days depending on device power and your listening habits. Store batteries in a cool, dry place away from metal objects that might short the contacts. Always open the battery door before storing your hearing aids overnight; this stops the battery from draining and allows moisture trapped inside to escape.
Keep spare batteries on hand—they cost $8–$15 per pack of four and are available from audiologists, pharmacies, and online retailers. Mark your calendar to replace dehumidifier silica gel or drying cartridges monthly, and schedule an annual professional cleaning with your audiologist.
What to Avoid
- Don't use alcohol or solvents on hearing aids; they damage the coating and internal components
- Don't expose devices to extreme heat (direct sunlight, car dashboards, or hair dryers)
- Don't drop or apply pressure to the delicate microphone ports
- Don't use regular cleaning cloths that leave lint; stick to microfiber or the cloth provided by your manufacturer
When to Seek Professional Help
If you notice persistent feedback, reduced battery life beyond normal, crackling sounds, or physical damage, contact your audiologist. Many providers offer 6-month or annual maintenance checks included in your purchase agreement, which typically costs $0 if covered or $50–$100 if purchased separately. Repairs outside warranty typically range from $150–$400 per device.

Frequently Asked Questions
Q: How often should I professionally clean my hearing aids? Most audiologists recommend a professional cleaning every 6–12 months, though daily home care prevents most buildup. If you're in a high-humidity environment or have excessive earwax production, schedule cleanings every 3 months.
Q: Can I use a hearing aid dehumidifier every night, or will it damage the battery? Yes, nightly use is safe and recommended; dehumidifiers actually extend battery life by removing moisture that causes corrosion and parasitic drain inside the battery compartment.
Q: What's the difference between water-resistant and waterproof hearing aids? Water-resistant devices (IPX4–IPX7 ratings) survive light rain or sweat but aren't designed for swimming; fully waterproof models (IPX8) can handle submersion for limited periods but still require drying afterward and cost 20–40% more.
