The earmold, or earpiece, is the custom-fit or dome-shaped component of a hearing aid that rests inside the ear canal. It directs sound from the receiver into the ear and secures the device in place. Consistent cleaning is necessary because earwax, skin oils, and moisture quickly block the small sound passages, diminishing sound quality or stopping the hearing aid from working entirely. Regular maintenance also prevents bacterial buildup and extends the device’s overall life.
Essential Tools and Preparation
Before cleaning, prepare a well-lit, clean, and stable work surface, such as a table covered with a soft towel. Gathering all necessary supplies beforehand ensures the delicate components are not left exposed while searching for tools. Standard hearing aid cleaning kits include specialized instruments. These tools typically feature a soft-bristle brush, a wax pick or wire loop, and a thin wire or threader for clearing tubing and vents. A soft, dry cloth or specialized hearing aid wipe is also necessary for removing surface debris and moisture. If you use a behind-the-ear (BTE) model, the earmold must be detached from the main electronic body before any cleaning involving moisture.
Daily Cleaning Procedures for the Earmold
Routine cleaning focuses on gently removing debris from surfaces that touch the skin. After removing the hearing aid, use the soft-bristle brush to sweep away visible earwax or skin flakes from the earmold exterior and the sound port opening. Hold the device with the openings facing downward so gravity pulls debris out instead of pushing it deeper. The brush can also be used gently on the microphone ports on the hearing aid body. Use the soft, dry cloth to wipe down the entire earmold and body to remove residual moisture or oils. This daily process helps maintain acoustic clarity.
For a more thorough clean, use a specialized hearing aid cleansing wipe or a cloth lightly dampened with a cleaning spray formulated specifically for hearing aids. This sanitizes the earmold surface that sits in the ear canal. This ensures the sound bore, the channel through which sound travels, remains clear for optimal performance. Remember, this routine cleaning does not involve soaking or submerging any part of the electronic device.
Addressing Stubborn Blockages and Moisture
Muffled or absent sound indicates a deeper obstruction requiring intensive cleaning. For hardened wax inside the sound port or a vent, use the specialized wax pick or wire loop to gently scrape or scoop the blockage out. Use this tool with care, avoiding puncture of the wax guard or receiver components. If BTE tubing is clogged, first detach the tubing and earmold from the main hearing aid body.
The detached tubing can be cleared by threading a thin, flexible cleaning wire through the length to dislodge wax. Alternatively, the mold and tubing can be washed in warm water with mild soap to soften and flush out debris. After washing, rinse components thoroughly to remove all soap residue and dry them completely. An earmold air blower, a small rubber bulb, effectively forces water and condensation out of the tubing and sound bore. Allow the earmold and tubing to air dry completely, ideally overnight, before reattaching them.
Moisture accumulation from humidity or perspiration can degrade sound quality or damage internal components. Using a drying kit or an electronic dehumidifier overnight draws out remaining moisture from the entire device. This protects the internal circuitry from corrosion, a common cause of malfunction. Never use a hair dryer or conventional oven to dry components, as excessive heat melts plastic parts or damages internal electronics.
Recognizing When Professional Care is Necessary
If issues exceed the scope of at-home cleaning, professional care is required. Persistent whistling or squealing (feedback), even after thorough cleaning, may signal an internal wax blockage or a fitting issue needing adjustment. Similarly, if the sound remains distorted, weak, or unclear after cleaning, the internal receiver or microphone may be partially or completely clogged.
Visible damage, such as a cracked earmold, brittle tubing, or a broken wire, necessitates professional replacement or repair. Professionals use specialized tools, such as vacuum systems and ultrasonic cleaners, to remove deeply embedded wax and moisture without damaging the device. Scheduling a professional clean and check every three to six months ensures optimal performance and extends the device’s lifespan. Users should never attempt to dismantle the hearing aid body beyond separating the earmold and tubing, as this voids the warranty.
