If you're an iPhone user, you know how crucial a clean and functioning microphone is for daily use. Whether it’s for making calls, recording audio, or interacting with Siri, the microphone plays a vital role.

But what happens when your iPhone mic starts picking up muffled sounds or, worse, stops working altogether? The culprit is often just a bit of dirt or debris clogging the mic. Fear not, as I’m here to guide you through the process of cleaning your iPhone microphone effectively and safely.

Step 1: Identify Your iPhone's Microphone Locations

First things first, identify where the microphones are on your iPhone. Most models have three: one at the bottom near the charging port, one near the rear camera, and one within the earpiece.

Knowing their exact locations is crucial to cleaning them properly, you can read this article to find the location of the microphones on your iPhone.

Step 2: Use the Right Tools

The key to a successful clean is using the right tools. A soft-bristled brush, like a new, clean toothbrush or an anti-static brush, works wonders. Avoid using anything metallic or overly abrasive, as these can damage the mic.

Step 3: Gentle Brushing

With your tool of choice, gently brush the microphone ports. Be careful not to push the dirt inside. A light, circular motion works best to dislodge any visible debris.

Step 4: Sticky Tack Method

For more stubborn grime, sticky tack, like this one, can be a lifesaver. Press a small piece gently against the microphone holes and lift. The tack will pick up dirt without leaving any residue.

Step 5: Avoid Liquids

While cleaning, avoid using liquids, including water and cleaning solutions. They can seep into the microphone and cause irreversible damage. If you need to use a cleaning agent, opt for a small amount of isopropyl alcohol on a cotton swab, but be extremely cautious.

Step 6: Test the Microphone

After cleaning, test the microphone. Record a voice memo or make a call to ensure it’s working properly.

If you still have any issue on your iPhone, and can’t afford the reparation cost, consider buying an external microphone for your most important calls.

Preventive Measures

To prevent future blockages:

  • Keep your iPhone in a clean environment.
  • Use a protective case.
  • Regularly clean the microphone using the steps above.


A clean microphone ensures your iPhone functions optimally for all your audio needs. By following these simple steps, you can maintain crystal-clear sound quality without risking damage to your device.

Remember, regular maintenance not only extends the life of your iPhone but also enhances your overall user experience. Keep those mics clean, and your iPhone will thank you!
