I wear a hearing aid in my left ear. It s an in the ear bud that is very inconspicuous. I ve had it for about 6 six months. Lately, I ve noticed it and my ear when I remove it at night, my fingers smell like a dank washcloth. I wipe it down daily with a clean, dry cloth and use the tools my audiologist gave me in order to clean out the 2 air channels. I m tempted to drop it in an alcohol bath, but I know this would probably kill it! Any suggestions?
