3 Hearing Aid Cleaning Mistakes That Could Damage Your Device

Keeping your hearing aids in top condition is essential for clear sound and a long lifespan. You’ve made an important investment in your hearing, and proper care is the best way to protect it. Many people, however, unknowingly make simple cleaning mistakes that can lead to costly repairs or poor performance. This guide will walk you through three of the most common errors and show you the right way to care for your devices.

Mistake 1: Using Household Cleaners or Alcohol Wipes

It might seem logical to grab a convenient alcohol wipe or a spritz of household cleaner to disinfect your hearing aids, but this is one of the most damaging things you can do. The sensitive electronic components and specially coated plastic casings are not designed to withstand harsh chemicals.

Why It’s a Problem:

Chemical Damage: Alcohol, solvents, and all-purpose cleaners can degrade the plastic shell of your hearing aid, causing it to become brittle, discolored, or cracked over time.
Electronic Failure: These liquids can easily seep into microphone ports, receiver openings, or battery compartments. Once inside, they can corrode the delicate internal circuitry, leading to static, intermittent function, or complete failure.
Clogging: Many cleaning wipes contain fibers or lotions that can break off and clog the tiny openings on your device, muffling sound.

The Correct Approach: Use the Right Tools Your hearing aids should only be cleaned with tools designed for the job. You don’t need harsh chemicals to keep them clean and functional.

Soft, Dry Cloth: For daily cleaning, simply wipe the entire surface of your hearing aid with a soft, dry cloth, like a microfiber cloth used for eyeglasses. This removes surface oils and debris without any risk of damage.
Specialized Brush: Use the small, soft-bristled brush that likely came with your hearing aids. This tool is perfect for gently brushing away debris from microphone ports and other crevices. Always brush away from the opening to avoid pushing particles inside.
Wax Pick/Loop: A wax pick or loop is a thin wire tool used to carefully scoop wax out of the sound outlet (the part where sound comes out). Use a gentle hand to avoid damaging the receiver.

Mistake 2: Introducing Moisture During Cleaning or Storage

Hearing aids are sophisticated electronic devices, and their biggest enemy is moisture. While many modern hearing aids are rated for water resistance, they are not waterproof. Exposing them to excess moisture, whether through cleaning or improper storage, is a direct path to malfunction.

Why It’s a Problem:

Corrosion: Moisture that gets inside the device can cause the battery contacts and internal electronic components to rust and corrode. This is often the cause of a hearing aid that suddenly stops working.
Sound Blockage: Humidity can cause moisture to condense inside the tubing of a Behind-The-Ear (BTE) model, blocking the path of sound and making it seem weak or dead.
Battery Issues: Moisture can shorten the life of your hearing aid batteries or cause them to fail completely.

The Correct Approach: Keep Them Dry at All Times A dry environment is a safe environment for your hearing aids.

Never Use Water: Do not run your hearing aids under a tap, soak them, or use a wet cloth for cleaning. The only part that can sometimes be washed is the earmold on a BTE model, but only after it has been completely detached from the electronic device itself. Always ensure the earmold is 100% dry before reattaching it.
Store Them Smartly: Never leave your hearing aids in a humid environment like a bathroom. At night, open the battery door to allow air to circulate and help evaporate any moisture that accumulated during the day.
Invest in a Dehumidifier: For best results, use a hearing aid dehumidifier or drying box. These come in two main types. A simple desiccant jar (like products from Stay-Dri) uses absorbent crystals to draw out moisture overnight. For a more thorough job, an electronic dryer (like models from Dry & Store or PerfectDry Lux) uses gentle heat and circulating air to actively dry and often sanitize your devices.

Mistake 3: Forgetting to Clean or Change the Wax Guard

Many users diligently wipe down the outside of their hearing aids but neglect a tiny, crucial component: the wax guard. This small plastic filter sits at the tip of the hearing aid receiver, preventing earwax from getting inside and damaging the speaker. Over time, this guard becomes clogged, which is the single most common reason a hearing aid stops producing sound.

Why It’s a Problem:

Muffled or No Sound: As the wax guard gets clogged, it blocks the sound from reaching your ear. Your hearing aid might sound weak, distorted, or seem completely dead, even with a fresh battery.
Internal Damage: If the guard is not replaced when it’s full, wax can be forced past it and into the receiver. Cleaning wax out of the internal receiver is a complex repair that must be done by a professional.

The Correct Approach: Inspect and Replace Regularly Make checking your wax guard a part of your daily cleaning routine.

Daily Inspection: When you wipe down your hearing aid at the end of the day, look at the tip. If you can see debris or wax in the small white filter, it’s time for a change.
Learn the Replacement Process: Changing a wax guard is simple once you know how. They come on small sticks or in dispenser wheels. One end of the tool has a point for removing the old, clogged guard, and the other end holds the new, clean guard to pop into place. Your audiologist can show you how to do this for your specific model.
Keep Spares on Hand: Don’t wait until your hearing aid stops working to think about the wax guard. Always have a spare pack of guards, like CeruStop or NanoCare, that are compatible with your specific hearing aid model.

Frequently Asked Questions

How often should I clean my hearing aids? You should perform a basic cleaning every day. A quick wipe with a dry cloth and a brush of the microphone ports takes less than a minute. A more thorough cleaning, including checking the wax guard, should also be done daily or at least several times a week.

Can I use a Q-tip to clean my hearing aid? No, you should avoid using Q-tips. Cotton fibers can easily break off and get stuck in the microphone ports or receiver openings, causing blockages. The size of the tip can also push wax deeper into the device’s openings rather than removing it.

What should I do if my hearing aid accidentally gets very wet? First, do not panic and do not use a hairdryer or microwave to dry it. Immediately remove the battery and wipe the entire device with a soft, absorbent cloth. Leave the battery compartment open and place the hearing aid in a hearing aid dehumidifier for at least 8-10 hours, or overnight. If you don’t have one, you can place it in a sealed container with uncooked rice or silica gel packets in a pinch, but a dedicated dehumidifier is far more effective. After drying, insert a new battery and see if it works. If not, contact your hearing care professional.
