The majority of foot massagers are very easy to clean. Just give them a quick wipedown with a damp cloth or a mild cleaning solution. Importantly, you should always make sure your foot massager is not plugged into a power outlet during cleaning. Furthermore, you should avoid getting the foot massager more than slightly damp, as getting the device wet could damage the motor inside.Some 360-degree foot massagers have removable covers that make them easier to clean, since they can be hard to see inside.
