Your hearing aids spend all day in a warm space exposed to earwax, oils and moisture. Over time, that buildup can block sound and shorten the life of your devices. A few minutes of care each day keeps them working the way they should. At Hear SF on Geary Boulevard in San Francisco, owner and hearing aid dispenser Michael Martinez, NB-HIS, helps patients build simple routines that protect their investment.
Every Day
- Wipe your hearing aids with a soft, dry cloth when you take them out.
- Use the small brush that came with your devices to gently clear the microphone openings.
- Look at the wax guard or filter for visible buildup.
- Store them in their case or charger overnight. For battery models, leave the battery door open so moisture can escape.
Every Week
- Replace the wax guard if it looks clogged or sound seems weak.
- Clean the domes or earmolds carefully, following your hearing care provider’s instructions.
- For behind-the-ear styles with tubing, check for moisture or blockages.
Every Month or as Needed
- Use a drying kit or dehumidifier, especially in damp weather or if you sweat a lot.
- Replace domes regularly, usually every one to three months.
- Schedule a professional cleaning and check every few months.
What to Avoid
Never use water, alcohol, cleaning sprays or tissues with lotion on your hearing aids. Remove them before showering, swimming or using hairspray, and keep them away from heat, like a car dashboard or hair dryer.
