Over-the-counter (OTC) and direct-to-consumer (DTC) hearing aids are sophisticated, highly miniature pieces of consumer technology. Because they sit inside or directly behind your ear canal for hours at a time, they are constantly exposed to moisture, sweat, skin oils, and earwax.
Without regular cleaning, earwax and debris can clog the sound ports, block the microphones, and cause your device to sound muffled, weak, or stop working entirely. In fact, earwax buildup is the single most common cause of hearing aid malfunction and repair requests [1].
This guide provides a straightforward, step-by-step cleaning routine to protect your investment and keep your hearing aids performing at their best.
The Essential Hearing Aid Cleaning Toolkit
Before you begin cleaning, you need the right tools. Most OTC hearing aids come with a basic cleaning kit, but you can also purchase these items affordably online. Never use sharp objects, household cleaners, or water to clean your devices.
| Tool | Purpose | How to Use It |
|---|---|---|
| Cleaning Brush | Removes loose wax, dust, and dry skin from physical buttons, seams, and outer casings. | Sweep gently across the device, holding it face-down so debris falls out. |
| Wax Loop or Pick | Extracts stubborn, packed earwax from the sound ports, receiver tips, and dome openings. | Gently scoop wax out. Never push the loop deep into the opening. |
| Vent Cleaner / Wire | Clears the narrow ventilation channels (vents) that run through custom molds or domes. | Thread the wire completely through the vent channel to push out debris. |
| Microfibre Cloth | Wipes down the entire exterior of the hearing aid to remove oils, sweat, and moisture. | Wipe the body and dome firmly but gently at the end of each day. |
| Dehumidifier / Dry Cup | Extracts residual moisture that accumulates inside the electronic housing during daily wear. | Place your hearing aids inside the drying jar or electronic dryer overnight. |
Step-by-Step Daily Cleaning Routine
Developing a daily habit is the easiest way to prevent wax buildup from hardening and becoming difficult to remove. We recommend performing this quick, two-minute routine every evening when you take your hearing aids out before bed.
Step 1: Wash and Dry Your Hands
Before touching your devices, wash your hands thoroughly with soap and water. Oils, dirt, and hand lotions can easily transfer to the hearing aid's delicate microphone ports and physical buttons.
Step 2: Hold the Device Face-Down
When brushing or picking wax, always hold the hearing aid upside down (with the sound port or microphone facing the floor). This ensures that gravity pulls the dislodged wax and debris out of the device, rather than letting it fall further into the delicate internal components.
Step 3: Brush the Exterior and Microphone Ports
Gently brush the entire body of the hearing aid. Pay close attention to physical buttons, volume toggles, and the tiny microphone openings. Dust and skin cells can accumulate in these crevices, blocking sound input.
Step 4: Wipe Down with a Microfibre Cloth
Use a dry, clean microfibre cloth to wipe down the outer shell and the ear dome or mold. This removes the thin film of sweat and skin oils that accumulates during the day.
Critical Warning: Never use water, rubbing alcohol, wet wipes, or household cleaning solvents on your hearing aids. Liquid can easily penetrate the seams of the housing, instantly shorting out the battery and frying the digital processor [2].
Step 5: Open the Battery Door (If Applicable)
If your hearing aids use disposable zinc-air batteries, open the battery door fully before storing them. This cuts off power, preserves battery life, and allows air to circulate through the compartment to dry out any internal moisture. If your devices are rechargeable, place them securely into their charging case.
Weekly Deep Cleaning and Wax Guard Replacement
Once a week, perform a more thorough inspection of your devices. This is when you should check the condition of your ear domes and wax guards.
Inspecting and Cleaning the Ear Domes
Ear domes are the soft, silicone tips that fit over the end of the hearing aid receiver and sit inside your ear canal.
- Pull the silicone dome gently to remove it from the speaker stem.
- Inspect the dome for tears, stiffness, or heavy wax buildup. If it is damaged or hard, replace it with a new one.
- If the dome is in good condition, wipe it thoroughly with your microfibre cloth. You can wash silicone domes in warm, soapy water, but they must be completely dry before you slide them back onto the hearing aid receiver.
Replacing the Wax Guard
Most modern receiver-in-canal (RIC) and in-the-ear (ITE) hearing aids feature a tiny, replaceable white filter called a wax guard (or wax filter) at the tip of the speaker. This filter acts as a barrier to stop earwax from entering the delicate speaker motor.
If your hearing aids sound weak, muffled, or completely dead, the wax guard is likely clogged and needs to be replaced.
- Locate your pack of replacement wax guards. They usually come on small plastic sticks. One end of the stick has a new, clean white filter; the other end has a black removal tool.
- Press the black removal tool directly into the center of the old, clogged wax guard on your hearing aid.
- Pull the stick straight out. The old filter will pop out on the end of the tool.
- Flip the stick around to the clean, white wax guard.
- Press the new filter directly into the empty speaker tip. Pull the stick straight out, leaving the new guard securely in place.
- Discard the used stick.
The Golden Rules of Hearing Aid Care
To ensure your hearing aids last for years, keep these three structural rules in mind:
- Avoid Moisture at All Costs: Take your hearing aids out before showering, swimming, or washing your face. Do not store them in the bathroom, where high humidity can cause condensation inside the electronics.
- Apply Cosmetics First: Hairdryers, hairspray, perfumes, face creams, and sunscreen can clog microphones and degrade plastic casings. Always apply these products and let them dry completely before putting your hearing aids in.
- Store Safely Away from Pets: Dogs and cats are highly attracted to the scent of their owner's earwax. Pets regularly chew on and destroy expensive hearing aids. Always store your devices in their protective case or charger, out of reach of pets.
Clear Verdict: Who Benefits from Which Routine?
While everyone should clean their devices, your specific routine depends on your device style and ear profile:
- If you have heavy earwax production: You must perform the daily dry-brushing routine and expect to replace your wax guards every 2 to 4 weeks.
- If you wear In-The-Ear (ITE) or Completely-In-Canal (CIC) devices: Your devices are highly vulnerable to wax clogging because the entire unit sits inside the canal. Daily wax picking is mandatory.
- If you wear Receiver-In-Canal (RIC) devices: Your main focus should be inspecting the silicone dome and replacing the wax guard immediately if the volume drops.
If you are unsure whether your cleaning routine is sufficient, or if you suspect a blockage is actually a change in your hearing profile, please consult a licensed hearing care professional.

Frequently Asked Questions
1. How often should I clean my hearing aids?
You should wipe down your hearing aids and gently brush the microphones and sound ports every single night. A deeper inspection, including cleaning the silicone domes and checking the wax guard, should be done once a week.
2. Can I use alcohol wipes to clean my hearing aids?
No. Rubbing alcohol and standard household disinfectant wipes contain harsh chemicals that can break down the protective coatings on your hearing aids, degrade the soft silicone domes, and damage the internal digital components. Only use a dry microfibre cloth or specialized, alcohol-free hearing aid wipes [2].
3. Why does my hearing aid sound quiet or dead even with a full battery?
The most common cause of a quiet or "dead" hearing aid is a blocked wax guard or dome. Earwax can completely block the sound port, stopping audio from reaching your ear. Try cleaning the dome and replacing the white wax guard filter.
4. How do I know when to replace my wax guard?
You should replace your wax guard if you physically see earwax blocking the white filter, or if you notice a sudden drop in sound quality, volume, or clarity that cannot be fixed by adjusting the volume settings. On average, most users replace their wax guards every 4 to 8 weeks.
5. What should I do if my hearing aid gets wet?
If your hearing aid drops in water, retrieve it immediately and turn it off (or remove the battery). Dry the exterior thoroughly with a towel. Do not use a hairdryer or microwave, as extreme heat will melt the components. Place the device in a sealed container with a hearing aid dehumidifier or dry uncooked rice for at least 24 hours.
