Hearing aids are powerful tools that help you stay connected to the world. But they’re also highly advanced electronic devices with tiny parts that can be damaged by exposure to things like humidity, hairspray, or even the transfer of soap and cleaning chemicals from your hands. Some hearing aid manufacturers have innovated device casing to be water resistant or waterproof and protect against sweat, rain, water splash, or an accidental drop. However, it's best to avoid the risks of moisture or chemicals whenever possible.
Here’s how to guard your hearing aids against damaging and corrosive elements to keep your tech staying clean and functional for the long term.
Environmental Hazards
Everyday conditions like heat, humidity, and dust can take a toll on your hearing aids.
Here is what to be aware of:
- Moisture and humidity: Being in prolonged settings with high humidity can corrode internal components. Take your hearing aids out and store them in a dry area far from the shower, sauna, or pool. If you’re in a humid environment, it’s a good idea to store your hearing aids in a dehumidifier or drying box overnight.
- Rain and sweat: Even small amounts of moisture can lead to long-term damage. Consider using a hearing aid sweatband or moisture guard if you are active outdoors or work up a sweat.
- Dust and debris: Windy environments or sandy areas can clog microphones and receivers. Read the manual that came with your hearing aids to understand how best to clean your devices. If you are unsure, reach out to a hearing care professional to discuss the appropriate tools for cleaning. Never use water or alcohol-based cleaners, as these can be damaging to the casing and internal components.
- Proper storage: Avoid keeping your hearing aids for long periods of time in the glove compartment of your car, on windowsills, or in a bathroom that collects steam.
Household Items
Many common cleaning products contain chemicals that can degrade or corrode hearing aid components. These can include:
- Cleaning sprays and wipes: Products like bleach and ammonia can break down the plastic housing of hearing aids and corrode internal circuits. Be sure not to allow your hearing aids close to these chemicals, and refrain from touching your hearing aids while cleaning.
- Hand sanitizer and soap: Alcohol and hydrogen peroxide can damage microphones and coatings. Dry your hands completely after washing and before handling your hearing aids.
Makeup, Hair, and Skin Care
Applying makeup or haircare can be as important to your daily routine as putting on your hearing aids. Be careful when applying products to avoid direct contact with your hearing aids, such as:
- Hair spray and dry shampoo: Fine particles can coat microphone ports and reduce sound quality. If possible, apply all hair products before putting on your hearing aids.
- Foundation and powder: Similarly, makeup dust can settle into tiny crevices on your hearing aids, causing feedback or distortion. Be careful when applying these products if wearing hearing aids.
- Lotions and creams: Oily or greasy residues can collect on your devices and attract dirt. Let lotion or cream products fully absorb into your skin before touching your hearing aids.
Your hearing aids are an investment in your quality of life. A few simple precautions can keep them performing at their best for years to come. If you have any questions about your environment, cleaning, or beauty routine, check in with a licensed hearing care professional. They will be able to guide you through proper cleaning techniques, offer deep cleaning and dehumidifying services, and discuss accessories that can keep your hearing technology as safe as possible.
