Why Cleaning Your Hearing Aids Matters

Regular cleaning and maintenance can help keep your hearing aids working at their best. Learn how to clean your hearing aids, remove wax and debris, care for domes and ear moulds, and recognise when your devices may need professional attention.

Your hearing aids work hard every day. They sit in a warm environment where they are exposed to earwax, moisture, skin oils, dust, and hair products. Over time, these can build up and affect how well your hearing aids perform.

The good news is that a simple cleaning routine can help keep your hearing aids working at their best, improve sound quality, and reduce the risk of unnecessary repairs. Regular maintenance can also help extend the life of your hearing aids.

A simple daily cleaning routine 

Cleaning your hearing aids doesn't need to be complicated. Most people can keep their devices in good condition with a quick daily routine.

Wipe them down

At the end of the day, use a soft cloth or tissue to gently wipe the outside of your hearing aids and remove any visible wax, dust, moisture, or debris.

Brush away wax and debris

Use the cleaning brush provided by your audiologist to gently remove wax from the microphone openings, domes, or ear moulds. Be careful not to push debris further into the device. 

Check the wax filter (if you have one!)

Wax filters help protect the internal components of your custom in-the-ear or receiver -in-the-ear hearing aids. If a filter appears blocked or the sound becomes muffled, it may be time to replace it. If you’re not sure how, the team at Bellbird Hearing can show you how to do this safely.

Replace domes regularly

If your hearing aids use soft domes, it's important to replace them regularly. Over time, domes can become blocked with wax, damaged, or lose their shape, which may affect both comfort and sound quality.

As a general guide, replace domes every few months, or sooner if they appear worn, discoloured, or blocked. If you're unsure how to change them, our team can show you how.

Clean Ear Moulds

Ear moulds can collect wax and debris, which may block sound and affect hearing aid performance.

Standard ear moulds (attached to plastic tubing) can usually be removed and washed in warm, soapy water. Make sure they are completely dry before reconnecting them to your hearing aid.

Custom moulds with built-in speakers should not be washed. Instead, wipe them with a dry cloth and use a cleaning brush to remove any wax from the sound outlet.
