How to care for your hearing aid

It's important to protect your hearing aid from damage. You should check and clean your hearing aid every day. This will help to keep it working for longer.

You can visit the National Hearing Aid Repair Centre every 3 to 6 months to have your device checked and cleaned. We can also help if your hearing aid is not working as usual or has stopped working.

Read these tips or our detailed guide for more information on caring for your hearing aid.

  • Clean your hearing aid using the small brush or the soft cloth that came with it.

Detailed guide to caring for your hearing aid


When you remove the hearing aid each day, wipe it off with a soft, dry cloth. Then inspect it to make sure there is no earwax build-up.

If you see earwax, you should remove this. Most manufacturers provide you with some sort of tool to clean the hearing aid with. This may be a brush, wire pick, or a combination of both.

Sometimes an old toothbrush can be helpful as well. Make sure that your tools are always clean before working on your aids.

Carefully remove any earwax from the hearing device. 

You should then open the battery door and place the hearing aids in their case. Opening the battery door reduces moisture build-up and prolongs battery life.

Never insert tools into the sound outlet. Doing so could damage the receiver. If you can't clean the hearing aid completely, ask us for help. 


Earwax build-up on your hearing aid can:

  • block sound to the ear
  • cause whistling
  • cause feedback

If you notice the volume on your hearing aid is becoming weak, earwax build-up could be the problem.

If you're still having trouble after checking the hearing aid yourself, we can check your hearing aid for you and repair it if needed.

Ask your doctor regularly to have your ear canals checked or cleaned.

Never remove the earwax from the ear yourself. Doing so could damage your ear.


Protect your hearing aid from moisture. Water can damage the electronic circuitry in the aid.

Always remove your aids before swimming, showering, bathing, or exercising.

Don't leave your aids in the bathroom where condensation can cause water damage.

Dry sweat from around the ears to protect your hearing aid.


Turn off your hearing aid when it is not in use. Make sure to keep extra batteries with you.

A dead battery should be removed right away. This stops the battery from leaking and damaging the hearing aid.

The average lifetime for a hearing aid battery varies. On average they last between 7 to 10 days, running 12 hours a day.

Replacing a battery

The sealing label should not be removed until you are ready to insert the battery into the hearing aid.

How to use a blower or puffer to remove moisture

A blower or puffer can be used to blow moisture from the earmould or tube. These are available in most hearing aid shops.

Disconnect the tube from the hearing aid and insert the blower into the tube. Squeeze the blower 10 to 15 times to remove moisture from the tube. 


If your hearing device has an earmould made of acrylic or silicone (behind-the-ear style aid), use a blower daily. This will blow out any moisture that accumulates in the tube.

You can also wash the earmould with a mild soap and water. You must disconnect the earmould from the aid before you wash it.

Make sure the earmould is completely dry and that no water is trapped inside the tube before re-attaching it to the hearing device.

The tubing on this type of aid should be replaced every 3 to 6 months or if it becomes hard or discoloured. In these cases, the tubing will lose its flexibility and sound will become weaker.
