How to Take Care of Your Hearing Aids: A Complete Maintenance Guide
By DEB’s Audiology Team – April 2026 – 12 min read
Article Summary
Complete hearing aid maintenance guide with a critical India-specific differentiator: dedicated monsoon and coastal humidity section covering Mumbai’s 85%+ humidity levels during June–September. Organised by daily routine, type-specific cleaning (BTE/RIC vs. ITE/CIC), moisture protection, battery care, common mistakes, professional servicing triggers, and device lifespan. Practical, scannable, genuinely useful. No international guide covers India’s climate challenges with this specificity.
Your hearing aids sit in or behind your ears for 10–16 hours a day. They are exposed to earwax, skin oils, sweat, dust, and – if you live in Mumbai or anywhere along India’s coast – some of the highest humidity levels in the world.
Proper care is not optional. It directly determines how long your hearing aids last, how well they sound, and how often you need repairs. The good news: a simple daily routine of five minutes or less is all it takes.
This guide covers everything you need to know – from daily cleaning for each hearing aid type, to monsoon-specific protection, to the signs that it’s time to see your audiologist.
Daily Cleaning Routine – 5 Minutes That Save Thousands
Clean your hearing aids every night when you remove them. Evening is better than morning because it gives the devices overnight to air dry.
Cleaning BTE and RIC Hearing Aids
These are the most common styles. The main body sits behind the ear; a tube or wire connects to an earmould or dome in the ear canal.
- Wipe the entire device with a dry microfiber cloth to remove surface oils and moisture
- Hold the hearing aid upside down (microphone facing the floor) and gently brush the microphone ports. This lets debris fall out, not in
- For BTE: detach the earmould from the tubing and wipe clean. If wax is stubborn, soak the earmould only (never the hearing aid body) in warm soapy water, rinse, and dry completely before reattaching. Use a tubing blower to clear any moisture from inside the tube
- For RIC: check the wax guard on the receiver (the small piece that sits in the ear canal). Replace the wax guard when it looks clogged or discoloured – typically every 1–2 months. Do not attempt to detach the receiver wire
- Place the hearing aid in a dehumidifier or drying case overnight
Cleaning ITE, ITC, CIC, and IIC Hearing Aids
These custom-moulded devices sit entirely in the ear. Because the entire device is inside the ear canal, wax and moisture exposure is higher.
- Wipe the outer surface with a dry microfiber cloth
- Use the wax pick or loop to carefully remove wax from the sound outlet (receiver) and ventilation opening. Be gentle – excessive force damages the receiver
- Brush the microphone ports (usually on the faceplate) with the device facing down
- Check and replace the wax guard when clogged
- If you use disposable batteries, open the battery door at night to let moisture escape and extend battery life
- Place in a dehumidifier overnight
Moisture and Humidity – Your Hearing Aid’s Biggest Enemy
Moisture damage is cumulative. You may not notice any effect day to day, but over weeks and months, internal corrosion builds up – leading to intermittent sound, static, battery drain, and eventually component failure.
- Use a hearing aid dehumidifier or electronic drying box every night – this is the single most important maintenance habit you can build
- Remove hearing aids before showering, bathing, or swimming (even IP68-rated devices are not designed for prolonged water exposure)
- After exercise or any activity that causes sweating, wipe the devices down and dry them
- Never store hearing aids in the bathroom or kitchen – steam and humidity are concentrated here
- Keep a small waterproof case in your bag for sudden rain
Mumbai Monsoon and Coastal Humidity – Extra Precautions
This section is critical for patients living in Mumbai, Goa, Kolkata, Chennai, and any coastal city in India. Standard international care guides are written for temperate climates with 40–60% humidity. Mumbai’s monsoon season (June–September) brings 85–95% humidity daily, along with sudden heavy rain, flooding, and persistent dampness.
During monsoon season, take these additional steps:
- Use an electronic drying box, not just silica gel. Basic silica gel desiccants saturate quickly in Mumbai’s humidity and become ineffective within days. An electronic drying box with a gentle heating element (such as the Phonak D-Dry or PerfectDry LUX) removes moisture more reliably and resets itself each cycle
- Carry a waterproof hard case whenever you go out. Mumbai rain is unpredictable. If you’re caught in a downpour, remove your hearing aids and store them immediately rather than letting them get soaked
- Replace wax guards more frequently. Higher humidity accelerates wax softening and buildup. During monsoon, check wax guards weekly rather than monthly
- If your hearing aids get wet, do not use a hairdryer or microwave. Blot gently with a dry cloth, remove any disposable battery, and place in a drying box. If the device was submerged, bring it to your audiologist as soon as possible
- Consider a monsoon check-up. At DEB’s, we recommend a professional cleaning and inspection at the start and end of monsoon season. Catching moisture damage early prevents expensive component failures
When choosing new hearing aids in India, ask about the IP (Ingress Protection) rating. An IP68 rating means the device is dust-tight and protected against submersion. Most premium 2026 hearing aids carry this rating, and in Mumbai’s climate, it is worth prioritising.
Battery Care – Rechargeable and Disposable
Rechargeable hearing aids:
- Charge every night in the designated charger – most devices reach full charge in about 3 hours
- Keep the charging contacts clean – wipe with a dry cloth if wax or debris is visible
- Store the charger in a cool, dry location (not on a windowsill or in the bathroom)
- Rechargeable batteries typically last 3–5 years before capacity declines noticeably – your audiologist can replace them when needed
Disposable battery hearing aids:
- Open the battery door at night to let moisture escape and conserve battery life
- Remove batteries entirely if the hearing aids will not be worn for more than a day
- Store spare batteries at room temperature in a dry place – not in the refrigerator (a common myth)
- Allow a new zinc-air battery to sit for 1–2 minutes after removing the tab before inserting it – this activates the battery fully
- In Mumbai’s humidity, disposable batteries may drain faster than the manufacturer’s stated life. Carry spares
What NOT to Do with Your Hearing Aids
- Never use water, alcohol, wet wipes, or household cleaners on your hearing aids. These damage coatings, seals, and electronics
- Never use a hairdryer, microwave, or direct sunlight to dry hearing aids. Excessive heat warps plastic housings and damages circuits
- Never wear hearing aids in the shower, pool, or sauna – even water-resistant models are not designed for prolonged water exposure
- Never leave hearing aids in a hot car, near a heater, or on a windowsill. Extreme temperatures damage batteries and housing
- Never attempt to open or repair the hearing aid yourself. Internal components are delicate and require professional tools
Never apply hair spray, perfume, or sunscreen while wearing hearing aids. Put these on first, let them dry, then insert your hearing aids
When to See Your Audiologist
Schedule a professional check-up if you notice any of the following:
- Sound quality has decreased or sounds muffled, even after cleaning
- Feedback (whistling) that wasn’t present before
- Intermittent sound – the hearing aid cuts in and out
- Physical damage – cracked housing, bent tubing, or broken receiver wire
- The hearing aid was submerged in water
- Battery drains significantly faster than usual (a sign of moisture damage)
- Skin irritation, itching, or discomfort in the ear
Even without problems, we recommend a professional cleaning and inspection every 4–6 months. At DEB’s Audiology, this service is included for all hearing aids fitted at our clinic.
How Long Do Hearing Aids Last?
With proper daily care and regular professional servicing, most hearing aids last 4–6 years. Some patients get 7+ years from well-maintained devices, although technology improvements may make an upgrade worthwhile before the device physically fails.
Factors that shorten lifespan: irregular cleaning, skipping dehumidifying routines, high earwax production, and exposure to Mumbai’s monsoon humidity without protection. Factors that extend lifespan: consistent daily cleaning, nightly dehumidifying, regular wax guard replacement, and periodic professional servicing.
