If you wear hearing aids, expect to need professional ear wax removal every six to twelve months. The aid itself blocks the canal’s natural self-cleaning system, which means wax accumulates faster than it would otherwise. Untreated, that build-up muffles your hearing, causes whistling, and can damage the aid’s receivers. Microsuction is the safest method for hearing aid users because it doesn’t introduce any water and lets us inspect both the canal and the aid in the same visit.
I’m Ish, the HCPC-registered audiologist behind the hearing solutions and aid fitting service at Hear With Ish. I see hearing aid wearers daily, and the most common reason for an unscheduled appointment is wax-related, the aid sounds wrong, the patient assumes the device is failing, and a 20-minute wax removal fixes everything.
Hearing aid wearers also have wider hearing health considerations beyond wax. The RNID has helpful patient-facing material on living with hearing aids, and the British Society of Hearing Aid Audiologists sets the standards your audiologist should be working to.
Why Hearing Aids Cause More Wax Build-Up
Your ear canal has a natural self-cleaning mechanism. The skin grows from the eardrum outwards, slowly carrying wax with it until it falls out unnoticed. Anything sitting in the canal disrupts this process.
Hearing aid domes, moulds, and tips block wax from migrating out. Instead, wax accumulates around and behind the device. Over weeks and months, what would naturally have cleared itself becomes a hard, impacted plug.
This isn’t a flaw in hearing aids, it’s just physics. Anything you put in your canal will do this. The solution isn’t to stop wearing your aids; it’s to manage wax actively.
What Wax Does to a Hearing Aid
Wax can affect hearing aids in three ways. First, it blocks the receiver, the small speaker that delivers sound to your ear. A blocked receiver makes the aid sound quiet, distorted, or completely silent.
Second, it interferes with the seal. A wax-fouled dome doesn’t sit properly in the canal, which causes whistling (feedback) and reduces sound quality.
Third, it sits between the aid and the eardrum, muffling sound regardless of what the aid is doing. You can be wearing a perfectly functioning hearing aid and still hear poorly because there’s a wax plug in front of the eardrum.
Signs Your Hearing Aid Has Wax Trouble
The aid sounds quieter than usual. Sound is distorted or scratchy. The aid whistles when it didn’t used to. Your ear feels blocked or full. You’re cleaning the aid more often but it’s not helping.
Any of these usually means wax has built up in your canal, on the aid itself, or both. The full troubleshooting checklist is in our Bluetooth hearing aids guide, which covers cleaning advice and connectivity issues for modern devices.
How Often to Have Your Ears Cleared
Most hearing aid wearers need professional wax removal every six to twelve months. Some need it every three or four months. A few don’t need it at all. It depends on your anatomy, how much wax you produce naturally, and how many hours a day you wear your aids.
If you wear your aids more than 10 hours a day or sleep with them in occasionally, you’ll likely need more frequent management. If you only wear them socially a few hours a week, you may need very little extra wax care.
Routine wax management can be combined with the aftercare package so you don’t have to remember separate appointments. Many patients book a single annual review covering hearing test, aid service, and wax check together.
Caring for the Aids Themselves
Replace wax guards or filters according to your manufacturer’s schedule, usually every two to four weeks. Wipe the aids daily with a clean, dry cloth. Use the brush included in your cleaning kit to clear any visible wax from the receiver. Open the battery door overnight to let any moisture evaporate.
If you’re not sure how to maintain your specific model, bring them in. Most manufacturers’ devices follow similar principles, but the exact procedure varies, and a quick demonstration in person makes the routine much easier.
If your aids have stopped working entirely, the issue may be deeper than wax. Our hearing aid repairs service can usually identify the cause in one visit and either fix it or arrange manufacturer servicing.
What Microsuction Looks Like for Hearing Aid Wearers
The procedure itself is identical for hearing aid wearers and non-users. The difference is that I’ll usually examine and clean the hearing aid afterwards too, replacing the wax filter and checking that the aid sounds normal once it’s back in your ear.
We can also book combined appointments, wax removal, aid service, and a quick hearing review, if that’s more convenient for you. It saves you from making multiple trips.
If your aid is rechargeable, we’ll check the contacts and the charging cradle for any wax residue while we’re at it. A small thing, but it’s a common cause of charging issues that patients trace back incorrectly to the battery.
Avoiding Wax Build-Up in the First Place
Use a few drops of olive oil once a week. Take your aids out for at least a few hours every day to let your ear canal breathe. Clean the dome or mould daily with the recommended cloth. Don’t ever use cotton buds inside the canal.
These small habits dramatically reduce the rate at which wax accumulates and extend the time between professional appointments.
Avoid using olive oil with the aid in the ear, take the aid out first, apply the drops, leave them to soak in, then wipe the canal entrance dry before reinserting. Drops on the aid itself can damage the speaker.
First-Time Hearing Aid Users
If you’re a new hearing aid wearer, expect to need a wax check three to six months after starting. Your ears need time to adjust to having something in them, and the first build-up usually comes faster than the cycles that follow. Read our first-time hearing aid guide for everything you need to know about the early weeks.
If you’re still choosing aids, the types of hearing aids guide and the invisible hearing aids overview between them cover what to expect from each form factor in terms of wax management.
Why Practitioner Choice Matters for Hearing Aid Wearers
Hearing aid wearers benefit particularly from continuity of care. The same audiologist sees how your wax patterns change over time, how your aids are performing, and what setting adjustments matter for you. Switching providers every visit makes it harder to spot trends.
Independent clinics also tend to carry a wider range of consumables, wax guards, domes, cleaning supplies, than a high-street chain tied to a single manufacturer. That matters when you need an unusual replacement at short notice.
Booking
If your aids aren’t sounding right, book a combined wax removal and aid service appointment through the ear wax removal page. We’ll have you hearing properly again in well under an hour.
Domes, Moulds, and Wax: How Aid Style Affects Build-Up
The style of hearing aid you wear changes how wax accumulates. Open-fit domes leave the canal mostly unsealed, so wax migration is only mildly affected. Closed domes and custom moulds form a tighter seal, which improves sound quality but reduces wax clearance more significantly. The trade-offs are covered in our guide to types of hearing aids.
Custom in-the-ear devices, including invisible discreet hearing aids, sit deeper in the canal than behind-the-ear models and tend to need more proactive wax management. The wax not only blocks migration but can also affect the microphones on the device. Most patients with these styles need a wax check every three to six months.
Open-fit aids and behind-the-ear models with thin tubing have the easiest wax-management profile, often only needing checks every nine to twelve months. If you’re choosing aids and wax build-up has been a recurring problem for you historically, that’s a relevant input into the style decision.
Working With Your Audiologist as a Long-Term Partner
Audiology in the UK is governed by professional standards that set the baseline for clinical practice. The British Society of Hearing Aid Audiologists publishes those standards and runs the accreditation framework most independent practices follow. Asking your audiologist about their accreditations is a reasonable thing to do — reputable practitioners are happy to talk through them.
The best hearing aid outcomes come from a long-term relationship with the same audiologist. They know your hearing pattern, your wax patterns, your aid settings, and your priorities. They can spot subtle changes that a one-off appointment would miss.
Most independent practices, including ours, structure aftercare around regular reviews. That gives the audiologist the chance to adjust settings, replace wax filters, and catch wax build-up before it causes problems. It’s a better experience for the patient and a better outcome for the equipment.
If you’ve recently switched providers or moved to Leicester, the easiest way to start is to book a wax check and aid review together via the contact page. I’ll examine the aids, look at the canal, and talk you through any changes you want to make to settings or routine.
Cleaning Frequency for Different Lifestyles
Active hearing aid wearers, regular gym users, walkers, swimmers in waterproof aids, need more frequent cleaning than less active patients because sweat and humidity accelerate wax build-up around the device. A daily wipe-down with the supplied cloth, plus weekly inspection of the wax filter, is the minimum routine for this group.
Less active wearers often manage well with twice-weekly cleaning and a monthly wax filter check. The aid itself stays drier, the canal accumulates wax more slowly, and professional intervention is needed less often.
Patients who work in dusty environments, builders, woodworkers, factory workers, sit between these two groups. The combination of dust and a sealed canal means wax accumulates faster than average and the aid microphones can become clogged with particulates. A daily clean plus a quarterly professional check is usually about right.
Whatever your routine, build it into a habit at the same time each day. The aids that fail prematurely are almost always the ones that weren’t cleaned consistently.
Frequently Asked Questions
Can I have microsuction with my hearing aids in?
No, the aids come out for the procedure. They go straight back in afterwards.
Should I have wax removal even if my hearing aids sound fine?
Yes, periodically. Wax can be present without causing obvious symptoms, and clearing it preventively keeps your aids performing at their best.
How do I know if it’s the aid or the wax causing problems?
If the aid sounds bad in both ears or stays bad after cleaning, the aid itself probably needs servicing. If only one ear is affected, wax is more likely the culprit.
Do behind-the-ear aids cause less wax than in-the-ear models?
Both block normal migration. In-the-ear styles tend to cause more concentrated wax issues because they sit deeper, but behind-the-ear domes still cause build-up around the canal entrance.
Will I damage my hearing aids by getting wax removed?
No. The aid is out of your ear during the procedure and isn’t affected. We’ll usually inspect and clean it as part of the appointment.
Can I use olive oil drops with my aids?
Yes, but take the aids out first. Apply the drops, let them soak in, wipe the canal entrance dry, then reinsert. Drops on the aid itself can damage the speaker.
How often should wax filters be changed?
Most manufacturers recommend every two to four weeks, though it depends on how much wax you produce. We’ll show you how to swap them yourself or do it at every appointment.
