How to clean iPhone microphone? To gently clean the external surfaces of the iPhone, you can use wipes with 70% isopropyl alcohol, a wipe with 75% ethyl alcohol or Clorox disinfectant wipes. It is essential not to spray products on the device (it is better to lightly spray a lint-free cloth first and then pass the latter over the product); it is important not to use aggressive products such as bleach, preventing moisture from penetrating into the openings and obviously not soaking the iPhone in cleaning products.

If talking on the phone with various people they complain of hearing your voice badly, a possible problem could concern the iPhone microphones (there are more than one built-in microphones). If any foreign element comes into contact with the microphones, such as dirt or sand, make-up, ink, soaps, detergents, acids or acidic foods or body creams, it is advisable to turn off the device and proceed with cleaning.
If the iPhone is stored in a case, remove it. Disconnect the phone from any power supply, locate the phone’s microphone, and proceed with cleaning.
The various points where the microphones are placed can be cleaned with a microfibre cloth or a delicate brush (avoid objects with an abrasive surface: these could cause damage). Do not absolutely use metal objects (eg paper clips), do not use water or any other type of liquid and do not use compressed air (it may seem like a good idea but often this does nothing but push the dirt inwards). With great care and delicacy, you can use a toothpick (to push debris outwards) or a suction system (always with care and being very careful).
You can use a magnifying glass to check for dirt and, as mentioned, a toothpick. Do not insert the latter firmly all the way, but limit yourself to small and delicate movements, for the escape of debris. A blower (such as those for cleaning camera sensors) or a compressed air dust remover can be used at the end of the cleaning, to remove smaller traces.
Even if the microphone doesn’t seem to work well, the problem could be software. Remove any screen protectors, films or cases, remove the dirt present in the openings of the iPhone and try to open an app to record voice or video memos and test the operation of the microphones.
If the microphone does not work in a specific app, open Settings> Privacy> Microphone and make sure the app is enabled.
If you have followed all the steps above, but still the microphone does not seem to be working, contact Apple Technical Support.
