Your ear canal produces earwax, which serves the important purpose of protecting and lubricating your ear. But wax buildup is one of the main causes for hearing aid repair, because wax clogs up the sound outlet and/or the ventilation opening, resulting in weak, distorted sound or absence of sound.
Your hearing aids are an important investment and have been designed to be both reliable and durable. Use a few minutes each day to clean them. Most hearing aids come with a filter to stop wax getting into the hearing aid or into the speaker or earpiece. Check the wax filter and replace it if necessary.
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 aids.
Do not use water, cleaning fluids, solvents or alcohol, as these could damage your hearing aids.
The speaker unit in RITE styles should be cleaned on a regular basis using a cloth to rub off any earwax. The domes that cover the speaker units should not be cleaned, but instead replaced if it is filled with wax.
