The maintenance mindset

Hearing aids are sophisticated electronics worn in one of the harshest environments imaginable — a warm, moist ear canal full of wax and skin debris. The fact that they last as long as they do is a testament to modern engineering. But they need your help.

The two biggest threats — earwax and moisture — are almost entirely preventable. A consistent maintenance routine addresses both and catches small problems before they become expensive repairs.

Daily maintenance routine (5 minutes)

1. Remove and wipe — when you take your aids out at night, wipe them with a soft, dry cloth to remove oils, sweat, and debris.
2. Brush the microphone ports — use the cleaning brush to gently clear any debris from the microphone openings.
3. Inspect the receiver/sound port — check for visible wax. If blocked, replace the wax guard or dome.
4. Store in the case or dehumidifier — never leave aids on a nightstand or in a bathroom. The case protects from drops and pets; a dehumidifier removes overnight moisture.
5. Open the battery door — if your aids use disposable batteries, opening the door overnight reduces battery drain and allows moisture to escape.

Weekly maintenance

• Replace dome tips if discolored, misshapen, or wax-clogged
• Check wax guards and replace if needed
• For BTE aids with earmolds: detach and wash the earmold with mild soap and warm water; dry completely before reattaching
• Inspect tubing (BTE) for cracks or hardening
• Check the wire (RIC) for kinks or damage

Monthly maintenance

• Replace wax guards preventively — even if they don't look blocked
• Clean the charging contacts (rechargeable aids) with a dry cloth
• Check that the charging case is clean and dry

Annual professional maintenance

Schedule an annual visit with your audiologist or hearing instrument specialist for:

• Professional deep cleaning (ultrasonic cleaning for earmolds)
• Tubing replacement (BTE aids)
• Receiver replacement if needed (RIC aids)
• Software updates and reprogramming if your hearing has changed
• Hearing test to check for changes in your hearing profile

Many providers include annual maintenance visits in the original purchase price. Check your purchase agreement.

Handling and storage tips

• Always handle over a soft surface — a dropped hearing aid on a hard floor is a common cause of damage
• Keep away from pets — dogs are attracted to the smell of hearing aids and will chew them
• Avoid extreme heat — never leave aids in a hot car, on a sunny windowsill, or near a heater
• Apply cosmetics first — hairspray, sunscreen, and perfume can clog microphone ports; apply before inserting aids
• Remove before water exposure — even IP68 aids should be removed before swimming, showering, or using a sauna
• Keep a spare set of supplies — wax guards, dome tips, and cleaning tools; running out means going without

Troubleshooting common issues

• Weak or no sound — check wax guard first; replace if blocked. Check battery/charge level.
• Whistling (feedback) — check that the dome or earmold is properly seated. Wax buildup in the ear canal can also cause feedback.
• Intermittent sound — often moisture in the electronics. Place in dehumidifier overnight.
• Distorted sound — low battery or moisture. Charge/replace battery and dry the aid.
• Aid won't turn on — check battery/charge. If rechargeable, check charging contacts for debris.
