Cleaning your hearing aids takes just a few minutes a day and makes a real difference in how well they perform and how long they last. Earwax, moisture, and skin oils are the main enemies, and a simple daily routine keeps all three in check. The process varies slightly depending on whether you wear behind-the-ear (BTE), receiver-in-canal (RIC), or in-the-ear (ITE) devices, but the core principles are the same: keep them dry, keep wax out of the openings, and never use water or chemicals on the electronic components.
Tools You’ll Need
Most hearing aids come with a small cleaning kit, but if yours didn’t, the tools are inexpensive and easy to find online or through your audiologist. A soft-bristled cleaning brush is the most essential item. It’s designed to sweep dust and earwax from battery compartments, microphone ports, and sound outlets without scratching surfaces. Some brushes include a small magnet on the opposite end for handling tiny batteries.
A wax pick or loop tool handles hardened wax stuck in sound outlets and receiver openings. A vent cleaner, which is a thin flexible wire, clears the small ventilation channels that run through earmolds and ITE shells. If you want one compact option, multi-tools that combine a brush, wax loop, and magnet are widely available and work well for travel or quick touch-ups.
Daily Cleaning Routine
When you remove your hearing aids each night, wipe the entire surface with a soft, dry cloth. This removes oils and moisture that accumulated throughout the day. Each morning before putting them in, check the earmold or dome opening for visible wax buildup. Catching it early prevents the kind of blockage that causes muffled sound or feedback whistling later.
Hold the device with the openings pointing downward while you brush so that loosened debris falls away from the ports rather than deeper into them. Use the brush to gently sweep the microphone ports, which are the tiny holes typically found on the top or back of the device. Never push sharp objects or pins into these ports. The microphone sitting just behind them is delicate and easily damaged.
Cleaning Behind-the-Ear (BTE) Devices
BTE hearing aids have a key advantage when it comes to cleaning: the earmold detaches from the electronic body. Disconnect the earmold from the tubing, then wash the earmold itself in warm, soapy water. Let it dry completely, ideally overnight, before reattaching it. The electronic part of the device should never get wet.
While the earmold is off, use your brush to clean the microphone ports on the main body. Wipe down the battery compartment or charging contacts with a lint-free cloth. If the tubing looks discolored or stiff, or if you notice moisture droplets inside it, your audiologist can replace it quickly.
Cleaning Receiver-in-Canal (RIC) Devices
RIC hearing aids place the speaker (receiver) directly in your ear canal, connected to the body by a thin wire. This wire and the soft dome at its tip need regular attention because they sit closest to earwax. Wipe the dome and wire with a soft, dry cloth to remove wax or debris. Keep the wire completely dry. No water, no liquid cleaners.
On the main body, brush or wipe the microphone port to clear wax and dust. Clean the battery compartment or charging contact pins with a lint-free cloth. RIC devices use a small wax guard, a tiny filter that sits on the end of the receiver wire underneath the dome. This guard is your first line of defense against wax reaching the speaker, and it needs regular replacement.
Cleaning In-the-Ear (ITE) Devices
ITE hearing aids sit entirely inside the ear, which means every surface is exposed to wax and moisture. Use a small brush to clean the microphone cover, receiver opening, and vent openings. For wax that’s stuck in the air vent, use a wax pick or loop tool to gently pull it free. Larger vents can be cleared with a dedicated vent cleaner by pressing it through the hole while twisting slightly. If the vent is very small and you can’t clear it, your audiologist has specialized tools for the job.
Wipe the entire casing with a soft, dry cloth. This is important: never use water, alcohol, or chemical wipes on ITE devices. Alcohol breaks down the surface coatings and plastics relatively quickly, and any liquid that reaches the electronics can cause permanent damage.
Replacing Wax Guards
Wax guards are small disposable filters that prevent earwax from reaching the speaker. They’re the single most common reason hearing aids start sounding muffled or producing feedback, and replacing them is something you can do at home in seconds. Most guards come in a dispenser stick: you push one end into the old filter to pull it out, flip the stick, and press the new filter into place.
Plan to replace your wax guards roughly once a month. If you produce more earwax than average, you may need to swap them more often. The signs that it’s time are straightforward: visible wax clogging the filter, muffled sound quality, or high-pitched whistling. Keeping a few spare packs on hand saves you from an unnecessary trip to the audiologist.
What Not to Use
Stick to dry cloths and the tools designed for hearing aids. Alcohol pads, even the ones marketed for general electronics cleaning, will degrade hearing aid surfaces quickly. Household cleaners, disinfectant sprays, and hand sanitizer are all off-limits. Water should only ever touch detachable earmolds, never the electronic components. Hair spray, sunscreen, and lotions can also gum up microphone ports and vents, so it’s best to put your hearing aids in after applying those products.
Managing Moisture
Sweat, humidity, and condensation are constant threats to hearing aid electronics. A dehumidifier or dryer gives your devices a safe, dry place to rest overnight and actively removes the moisture that builds up during the day.
Passive dehumidifiers are the simplest and most affordable option. They use silica gel beads or crystals inside an airtight canister. You place your hearing aids inside, close the lid, and the absorbent material draws out moisture overnight. The beads need to be recharged or replaced periodically, typically when they change color.
Electronic dryers are more advanced. They use gentle heat and a fan to remove moisture more thoroughly, and many models include UV-C light that sanitizes the devices at the same time. Some have timers for a faster drying cycle when you’re in a hurry. Either option works well. If you live in a humid climate, sweat heavily, or have had moisture-related repairs before, the electronic version is worth the investment.
Professional Cleaning
Even with diligent daily care, hearing aids benefit from a professional cleaning every six months. Audiologists have ultrasonic cleaners and vacuum tools that reach buildup you can’t address at home. These visits also give your provider a chance to check the tubing, test the electronics, and catch small problems before they become expensive repairs. Many practices include these cleanings as part of your ongoing care plan at no extra charge.
