When you stick sophisticated electronics in your greasy ears everyday, it stands to reason that they’re going to get a little bit gunked up from time to time. When Apple AirPods get clogged up with earwax and sweat, it not only looks disgusting, it can make the volume quieter in one or both AirPods.

I’ve owned both first generation and second generation standard AirPods, and my favorite super-simple way of cleaning them is a little tacky. In this video, I show you my favorite way to not only clean out earwax build-up from your AirPods, but also restore the volume. All it takes is a little poster putty like Loctite’s Fun Tak.
