A microphone collects dust, skin oil and saliva over time, and each of these can affect the sound. A clean microphone sounds more consistent, and it lasts longer. Cleaning is simple, but it needs care, because some parts are delicate.
Clean the body gently
Wipe the outside with a dry or lightly damp microfibre cloth. Avoid soaking the cloth, and never spray cleaner directly onto the microphone. Keep liquid away from the connector and any switches.
Check the grille
The grille protects the capsule. Some microphones can be cleaned with a soft brush, while others should not be touched at all. Check the manual before you clean the grille, and never poke inside the capsule.
Clean the windscreen and pop filter
A pop filter or foam windscreen collects saliva and dust, and it can smell over time. Wash a mesh pop filter in warm water with mild soap, then let it dry fully. Replace a foam windscreen when it becomes dirty or stiff. The pop filter comparison explains which one suits which job.
Store it well
Keep the microphone in a dry place, away from heat and dust, and in a case or a cover if you have one. Coil the cable loosely, rather than tightly, so it does not kink.
Limits
If a microphone is damaged, has a loose connector or sounds wrong after cleaning, stop using it and check the manufacturer’s guidance. A repair is usually better than a DIY fix on a delicate part.
