How to clean hearing aids safely and effectively

Knowing how to clean hearing aids properly is essential for maintaining clear sound quality, comfort and long-term performance. Hearing aids are sophisticated electronic devices that are worn for many hours each day, often in warm and humid conditions inside or around the ear. As a result, they are regularly exposed to earwax, moisture, sweat, skin oils and environmental debris. Without consistent care, this build-up can affect sound clarity, cause blockages and even lead to avoidable repairs. Regular cleaning not only protects the delicate internal components but also supports better hearing outcomes. Even a small amount of wax can obstruct microphone ports or receivers, resulting in muffled or distorted sound. Moisture, if left unmanaged, may damage circuitry or reduce battery efficiency, particularly in rechargeable models. A proper cleaning routine does not need to be complicated. With simple daily wiping, weekly detailed checks and occasional component replacement, most common issues can be prevented. Using the correct tools — such as a soft cloth, small brush and wax guards — ensures safe and effective maintenance. Understanding the correct techniques and what to avoid is equally important. With the right approach, you can extend the lifespan of your hearing aids and ensure they continue to perform reliably.

Ultimately, consistent cleaning ensures that hearing aids continue to provide clear, comfortable amplification. It protects your investment, extends device lifespan and supports better communication and quality of life.

If sound remains muffled after cleaning, consult your audiologist for professional servicing.

Consistent maintenance not only preserves sound clarity but also reduces the risk of faults and costly repairs, ensuring your hearing aids continue to support your hearing effectively.

Regular, careful cleaning helps ensure reliable performance and extends the lifespan of your hearing aids.

Hearing aid tubes, commonly found on behind-the-ear (BTE) models, need regular cleaning to prevent wax build-up and moisture from affecting sound quality. Blocked or stiff tubing can reduce amplification and cause distortion.

1. Start by switching off the hearing aid and carefully detaching the tubing from the main device, if it is designed to be removed. Always follow your manufacturer’s or audiologist’s instructions before disconnecting any parts.
2. If the tubing is attached to an earmould, separate the earmould from the hearing aid first. Wash the earmould and tubing (only if detachable and approved for washing) in lukewarm water with a small amount of mild, fragrance-free soap. Rinse thoroughly to remove any soap residue.
3. Shake off excess water and use a specialised air blower (earmould puffer) to push air through the tube and remove trapped moisture. It is essential that the tubing is completely dry before reconnecting it to the hearing aid. Leaving it to air dry overnight on a clean towel is often recommended.
4. Inspect the tubing for signs of stiffness, yellowing or cracks. Tubes naturally harden over time and typically need replacing every few months.

Regular cleaning and timely replacement help maintain clear sound transmission and extend the overall lifespan of your hearing aid.

Hearing aid domes are the small, soft silicone tips that sit inside the ear canal. Because they come into direct contact with earwax and moisture, they require regular cleaning to maintain sound quality and hygiene.

1. Start by switching off the hearing aid and gently removing the dome from the receiver or thin tube. Most domes simply pull off, but always follow the manufacturer’s guidance to avoid damaging the device.
2. Once removed, wipe the dome with a soft, dry cloth to clear away surface wax. If there is more noticeable build-up, you may clean the dome using lukewarm water and a small amount of mild, fragrance-free soap. Rinse thoroughly to remove any residue.
3. After washing, allow the dome to dry completely before reattaching it. Moisture trapped inside the dome can affect sound transmission and potentially damage the receiver. It is best to leave the dome to air dry naturally on a clean towel.
4. Inspect the dome for signs of wear, such as tears, stiffness or discolouration. Domes typically need replacing every one to three months, depending on usage and earwax production.

Regular cleaning and timely replacement help ensure clear sound, comfort and reliable performance from your hearing aids.

Hearing aid moulds (also called earmoulds) sit inside the ear and can collect earwax, moisture and debris. Regular cleaning is important to maintain sound quality, hygiene and comfort.

1. First, switch off your hearing aid and carefully detach the earmould from the main electronic unit. Never wash the hearing aid itself — only the mould if it is designed to be removed. If you are unsure, check the manufacturer’s instructions or ask your audiologist.
2. Wash the earmould in lukewarm water with a small amount of mild, fragrance-free soap. Gently rub the mould to remove wax build-up. Avoid using very hot water, harsh detergents or alcohol-based cleaners, as these can damage the material.
3. Rinse thoroughly to remove all soap residue. Shake off excess water and use a small air blower (earmould puffer) to push air through the tubing and remove trapped moisture. This step is important to prevent sound blockage.
4. Allow the earmould to dry completely — ideally overnight on a clean towel — before reconnecting it to the hearing aid. Reattaching while damp can damage the electronics.
5. Inspect the mould regularly for cracks, hardening or discolouration. If you notice changes in fit or sound quality, consult your hearing care professional for advice or replacement.

Earwax build-up is one of the most common causes of reduced sound quality in hearing aids. Regular removal helps prevent blockages, distortion and potential damage.

1. Start by switching off your hearing aid. For battery-operated models, open the battery compartment. Place the device on a clean, well-lit surface so you can clearly see small openings.
2. Use the small cleaning brush or wax pick provided by your audiologist. Gently brush around the microphone ports, receiver openings and vents to remove visible wax. Always brush away from the openings to avoid pushing wax further inside the device. Never use sharp objects such as pins or needles, as these can damage delicate components.
3. If your hearing aid has a wax guard or filter, check whether it is blocked. Most modern devices include replaceable wax guards designed to protect the receiver. If clogged, replace the guard following the manufacturer’s instructions.
4. For behind-the-ear models with domes or earmoulds, remove the dome or detach the earmould (if appropriate) and clean it separately. Domes can be wiped or washed if permitted, while earmoulds may be rinsed in lukewarm soapy water and fully dried before reattachment.

If sound remains muffled after cleaning, consult your audiologist for professional maintenance and inspection.

• In most cases, it is not recommended to use alcohol wipes or rubbing alcohol directly on your hearing aid unless the manufacturer specifically states that it is safe to do so. Hearing aids are delicate electronic devices with sensitive microphones, receivers and internal circuitry. Alcohol can damage protective coatings, dry out plastic components and potentially seep into small openings, leading to performance issues.
• While alcohol-based wipes may seem convenient for disinfecting, repeated use can cause parts such as domes, tubing and casing materials to become brittle or discoloured over time. Strong cleaning agents may also weaken adhesive seals that protect against moisture. For routine cleaning, it is best to use a soft, dry, lint-free cloth to wipe the outer surface. A small brush designed for hearing aids can be used to remove wax from openings. If disinfection is necessary, especially for health reasons, ask your audiologist whether manufacturer-approved cleaning wipes are suitable for your specific model.
• If you are unsure, always consult your hearing care professional or refer to the user guide. Using the wrong cleaning products can shorten the lifespan of your device and may invalidate the warranty.

• Wax guards (also called wax filters) should typically be changed every four to eight weeks, depending on how much earwax you naturally produce and how often you wear your hearing aids. These small components sit at the end of the receiver and are designed to protect the internal parts from wax and debris.
• However, there is no single rule that applies to everyone. Some people may need to replace their wax guards more frequently — even every two to four weeks — if they produce a higher amount of earwax. Others may find they last longer.
• A clear sign that it is time to change the wax guard is a noticeable reduction in sound quality. If your hearing aid sounds muffled, weak or distorted, and the battery is functioning properly, a blocked wax guard is often the cause. Replacing it is usually quick and can restore normal performance immediately.
• It is a good idea to check the wax guard weekly during routine cleaning. Even if it does not look completely blocked, replacing it regularly helps maintain consistent sound clarity.
• If you are unsure how often to change them, your audiologist can provide guidance based on your individual needs and device model.

• Yes, using a hearing aid drying box is highly recommended, especially if you wear your devices daily. Hearing aids are small electronic instruments that are sensitive to moisture from sweat, humidity and earwax. Even in the UK’s often damp climate, moisture can accumulate inside the device and affect performance over time.
• A drying box (or dehumidifier) safely removes residual moisture overnight. Simply place your hearing aids inside before you go to bed. The box gently draws out water vapour, helping to protect internal components such as microphones, receivers and batteries. This can reduce crackling, distortion and intermittent faults that are often caused by trapped moisture.
• Drying boxes are especially useful if you live in a humid environment, exercise regularly, or notice that your hearing aids become damp or perform inconsistently. They are also beneficial for rechargeable models, as moisture around charging contacts may affect reliable charging.
• While a drying box does not replace regular cleaning, it enhances device longevity and reduces the risk of costly repairs. Many hearing care professionals in the UK recommend using one as part of a daily maintenance routine. If you’re unsure which model to choose or how to use it, your audiologist can provide personalised advice.

Cleaning rechargeable hearing aids requires the same care as battery-operated models, with extra attention to the charging contacts. Regular maintenance helps ensure reliable performance and consistent charging.

• Start by switching off the device. Wipe the outer casing daily with a soft, dry, lint-free cloth to remove earwax, oils and moisture. Avoid using water, alcohol or household cleaning products, as these can damage internal electronics.
• Use a small hearing aid cleaning brush to gently remove wax from microphone ports, receiver openings and vents. Always brush away from openings to prevent pushing debris inside.
• Pay particular attention to the charging contacts. These small metal points must remain clean and dry for proper charging. Gently wipe them with a dry cloth. If necessary, use a clean, dry cotton bud to remove visible debris — but never apply liquid cleaners.
• If your device has domes, check them regularly for wax build-up and replace them as recommended. Wax guards should also be inspected and changed when blocked or every four to eight weeks.
• Finally, store your hearing aids in their charging case in a dry place. Many audiologists recommend using a drying box for added moisture protection. Consistent care helps maintain battery efficiency, sound clarity and overall device lifespan.

Most hearing care professionals recommend having your hearing aids professionally serviced every six months. Even with careful daily and weekly cleaning at home, a routine check-up helps ensure your devices continue to perform at their best.

• During a professional service, your audiologist will carry out a deep clean using specialist tools that remove compacted wax and debris from areas you cannot safely access yourself. They will also check the microphones, receivers, tubing, charging contacts and battery performance. For behind-the-ear models, tubing may be replaced if it has hardened or discoloured.
• Regular servicing also allows your audiologist to assess whether your hearing prescription needs adjusting. Hearing can change over time, and small programming updates may significantly improve clarity and comfort.
• You may need more frequent appointments if you produce a high amount of earwax, live in a humid environment, or notice issues such as muffled sound, distortion or intermittent performance.
• In addition to routine six-month checks, you should book an appointment promptly if your hearing aids stop working properly. Preventative servicing helps extend the lifespan of your devices and reduces the likelihood of costly repairs.

A good hearing aid cleaning kit equips you with the essential tools to keep your devices working clearly and reliably. Because hearing aids are small and sensitive, using the right items makes routine maintenance safe and effective.

Different types of hearing aids require slightly different cleaning approaches. Using the correct tools for your specific model helps maintain sound quality and prolong device lifespan.

Professional servicing every six months — or more often if needed — helps catch issues early, maintains optimum performance and can extend the life of your hearing aids. If you experience persistent muffled sound, feedback or discomfort, book a professional clean sooner.
