How to Clean and Care for Hearing Aids (and Connect Them to Your Phone)

Hearing aids last longer and sound better with a short daily routine. Wipe them with a dry cloth, brush wax and debris from the microphone and sound openings, and change wax guards and domes regularly. Charge rechargeable aids every night, or open the battery door of disposable-battery aids. Keep them dry and away from heat, and pair them with your phone for calls and audio.

Before you start

  • Your hearing aid cleaning kit (brush and wax loop or pick)
  • A soft, dry cloth
  • Spare wax guards, domes and batteries (if used)
  • Your hearing aid charger or case

Method 1 Clean them every day

  1. Step 1: Wash and dry your hands

    Clean, dry hands stop oil and dirt getting onto the hearing aids.

  2. Step 2: Hold them over a soft surface

    Work over a towel or table so they don’t break if dropped.

  3. Step 3: Wipe the outside

    Wipe the hearing aids, earmoulds or domes with a soft, dry cloth or a cleaning wipe made for hearing aids. Never use water, alcohol or household cleaners unless your audiologist says so.

  4. Step 4: Brush the openings

    Hold the aid with the opening facing down and gently brush the microphone ports and sound outlet so debris falls out, not in.

  5. Step 5: Clear wax

    Use the wax loop or pick to gently remove wax from the earmould or dome opening, without pushing it deeper.

Method 2 Replace wax guards and domes

  1. Step 1: Check the wax guard

    Many aids have a small white filter (wax guard) where sound comes out. If sound is weak or muffled, it may be blocked.

  2. Step 2: Change the wax guard

    Use the tool from your wax guard pack: insert the empty end to pull out the old guard, then use the other end to push in a new one. Follow your model’s instructions.

  3. Step 3: Replace domes

    Change soft domes every 1–3 months, or sooner if they’re discoloured, stiff or split. Make sure they click firmly onto the receiver so they can’t come off in the ear.

  4. Step 4: Clean earmoulds

    Custom earmoulds that detach from the aid can usually be washed in warm, soapy water, rinsed and dried completely; check with your audiologist first and never wash the hearing aid itself.

Method 3 Look after the power

  1. Step 1: Rechargeable aids

    Place them in the charger every night. Make sure they sit properly and the charging light shows.

  2. Step 2: Disposable batteries

    Open the battery door overnight to save power and let moisture escape. Remove the sticker from a new battery and wait about a minute before inserting it.

  3. Step 3: Carry spares

    Keep spare batteries in a bag or purse, and change them when you hear the low-battery warning.

  4. Step 4: Keep batteries away from children and pets

    Button batteries are very dangerous if swallowed. Store them safely and get urgent medical help if one is swallowed.

Method 4 Protect them from damage

  1. Step 1: Keep them dry

    Remove hearing aids before showering, swimming or using hairspray. A drying box or dehumidifier can remove moisture overnight.

  2. Step 2: Avoid heat

    Don’t leave them in a hot car, on a radiator or in direct sun.

  3. Step 3: Store them safely

    Keep them in their case when not in use, out of reach of pets; dogs are attracted to their smell.

  4. Step 4: Put them in last

    Put hearing aids in after hair products and makeup.

Method 5 Connect hearing aids to your phone

  1. Step 1: iPhone

    For Made for iPhone hearing aids, go to Settings > Accessibility > Hearing Devices, open the battery doors or restart the aids to put them in pairing mode, and tap their name when it appears.

  2. Step 2: Android

    Put the hearing aids in pairing mode, then go to Settings > Connected devices > Pair new device, or for compatible aids Settings > Accessibility > Hearing devices. If you have two, wait for the first to connect before selecting the second.

  3. Step 3: Use the manufacturer’s app

    Most brands have an app for adjusting volume, programmes and finding lost hearing aids.

Troubleshooting

No sound

Check the battery or charge, make sure the aid is switched on, and replace the wax guard. Clean the dome or earmould opening.

Whistling or feedback

Re-seat the aid properly in your ear, check the dome size and fit, and see a doctor if you may have earwax build-up.

They won’t pair with my phone

Restart the hearing aids and your phone, remove old pairings, and make sure your phone’s software is up to date.

Frequently asked questions

How long do hearing aids last?

Typically around 4–6 years with good care.

Can I clean hearing aids with alcohol wipes?

Use only wipes made for hearing aids. Alcohol can damage some materials.

Should I wear hearing aids all day?

Yes, usually. Wearing them consistently helps your brain adjust and get the most benefit.

Summary

Each day, wipe your hearing aids with a dry cloth and brush the openings, and replace wax guards and domes regularly. Charge them nightly or open battery doors, keep them dry and away from heat and pets, and pair them with your phone for calls and audio. See your audiologist for regular checks or if the sound changes.
