How to clean behind-the-ear (BTE) hearing aids

Your hearing aids are an important investment and have been designed to be both reliable and durable. Take a few minutes each day to clean them. Your ear canal produces earwax, which serves the important purpose of protecting and lubricating your ear. However, wax buildup is one of the main causes for hearing aid repair. Wax clogs up the sound outlet and/or the ventilation opening, resulting in weak, distorted sound or absence of sound. Most hearing aids come with a filter or other device to stop wax from getting into the hearing aid. Check the wax filter and replace it if necessary.

Your Hearing Care Professional can advise you about the details of your hearing aids' wax protection system.

Cleaning the speaker unit and shell

As a general rule, clean your hearing aids each day with a soft, dry cloth. Make sure your hands are clean and dry before handling your hearing aids.

Important notice: do not use water, cleaning fluids, solvents or alcohol, as these could damage your hearing aids.

The speaker unit in receiver-in-the ear hearing aids (RITE models) should be cleaned on a regular basis using a cloth to rub off any earwax. The domes (silicone tips) that cover the speaker units should not be cleaned, but instead replaced at least once a month.

Use the MultiTool for cleaning hearing aids

Important notice!

Before handling a hearing aid, make sure to hold it over a soft surface to avoid damage if you drop it.
