Many patients ask me how they can properly care for their hearing aids. Keeping your hearing aids clean and free of dirt and dust is one of the most important steps to taking care of them. Not only does keeping them clean help improve the sound quality now, it also helps to ensure that the hearing aids continue working long term. One of the most important cleaning steps hearing aid users can take is to use a cleaning brush to clean away dirt, dust, and earwax.
There are several types of brushes that can be used. My favorite cleaning brush looks very much like a toothbrush, but is designed for hearing aids. The bristles are much softer than a regular toothbrush, and bend easily to get down into all of the nooks and crannies of your hearing aids.
Another commonly used brush is short with small bristles. The small size is helpful for cleaning hard-to-reach places in the hearing aids, such as inside the battery door. Whatever brush type you use, make sure to brush off your domes, receivers, hearing aid shell, and inside the battery door. Be very mindful, however, of your microphones, as you do not want to scratch them.
