How to clean ITE hearing aids

Cleaning In-the-Ear (ITE) hearing aids is an essential part of keeping them clear, comfortable, and reliable. Because they fit completely or partly inside the ear canal, ITE hearing aids are constantly exposed to earwax, moisture, and oils from the skin. Over time, this build-up can block hearing aid vents and microphones, muffle sound, or even damage internal components. Regular cleaning—done correctly—helps prevent these issues and extends the life of your devices. The process is simple and can be done safely at home using a few basic tools.

Having the right tools makes cleaning faster, safer, and more effective. A basic ITE cleaning kit should include:

• Soft cleaning brush: Removes dust and earwax from microphone ports, vents, and openings.
• Wax pick or wire loop: Helps gently lift hardened wax without damaging the receiver.
• Vent cleaner: A fine, flexible wire for clearing ventilation holes in custom shells.
• Dry, lint-free cloth: For wiping the outer surface of the hearing aid each day.
• Replacement wax guards or filters: Designed specifically for your model—never use generic ones.
• Hearing aid drying case or dehumidifier (optional but recommended): Helps remove moisture overnight, especially useful if you live in a humid climate or sweat frequently.

Keep these items together in a clean, dry container and replace worn brushes or tools regularly. At Miracle-Ear, you can receive cleaning tools with your hearing aid purchase. 

Earwax is the most common cause of reduced sound quality or feedback in ITE hearing aids. Because the device sits directly in the ear canal, wax can easily collect around the sound outlet. Here’s how to safely remove it:

1. Brush first. Hold the device face down and use a small, soft brush to loosen and sweep away dried wax.
2. Use a wax pick or wire loop. If wax remains in the sound outlet or vent, gently lift it out using the pick. Avoid inserting the tool too deeply.
3. Clean the vent. If your ITE model includes a vent, use a vent cleaning wire or flexible thread to carefully remove blockages.
4. Inspect the wax guard. Many ITE hearing aids include a small, removable wax guard at the receiver opening. If it appears clogged or discolored, replace it immediately.

Never use needles, pins, or toothpicks; they can puncture delicate components or push wax deeper inside the ear.

The microphone openings on ITE hearing aids are very sensitive and should be handled carefully:

• Hold the hearing aid upside down so debris can fall out naturally.
• Use a soft brush to gently sweep across the microphone openings using light, short strokes.
• Avoid blowing air or inserting objects into the ports—this can force debris deeper or introduce moisture.

If sound remains muffled after cleaning, your microphone filters may need professional replacement from your hearing care professional. Regular brushing of the microphone area helps preserve sound clarity and prevents extensive repairs.

No. Never submerse or rinse your ITE hearing aids in water. Water can damage sensitive electronic components and lead to permanent malfunction. Instead, clean the surface with soft, dry cloths and use a brush and wax pick for debris removal. If your hearing aids get wet, turn them off, open the battery compartment, and place them in a drying case or dehumidifier overnight. Always keep them away from sinks, showers, and humid bathrooms.

Yes, it’s highly recommended. ITE hearing aids sit inside the ear canal, where they’re exposed to constant warmth and humidity. Moisture from sweat, earwax, or daily temperature changes can easily build up inside the device. A drying case or dehumidifier removes this moisture overnight, protecting the internal microphones and receivers from corrosion and prolonging the hearing aid’s lifespan. There are two main options:

• Passive drying cases, which use drying capsules to absorb moisture.
• Active electronic dehumidifiers, which use gentle heat or air circulation for more thorough drying.
• Using one every night, especially if you live in a humid environment or perspire heavily, helps prevent muffled sound and extends the reliability of your hearing aids.

A drying case or dehumidifier may not be provided at the point of sale, so it’s important to contact your Miracle-Ear hearing care professional to learn where these can be obtained.

No, regular, gentle cleaning protects your hearing aid, as long as it’s done correctly. Daily removal of earwax and debris prevents buildup that could block the sound outlet or microphone ports. Problems only occur when users apply too much pressure, use sharp objects, or expose the hearing aid to moisture or chemicals. Avoid these common mistakes:

• Don’t insert cleaning tools deep into the openings
• Never use water, alcohol, or household cleaners
• Avoid spraying disinfectants directly onto the hearing aid

Consistent, light cleaning preserves your device’s performance and minimizes the need for repairs. If you’re uncertain, ask your hearing care professional to demonstrate the correct cleaning technique during your next visit.

You may need professional maintenance if your ITE hearing aid sounds muffled, distorted, or quieter even after cleaning. Other warning signs include:

• Persistent feedback or whistling
• Visible wax deep inside the sound outlet or vent
• Moisture or condensation under the battery door
• Discolored or clogged wax guards or filters

Do not attempt to dig out deep wax yourself: hearing care professionals have specialized suction tools and microscopes to clean delicate components safely. A professional cleaning usually takes just a few minutes and can restore clear sound immediately. Scheduling a clinic cleaning at your local Miracle-Ear every 6 to 12 months will help keep your hearing aids performing at their best.
