How to clean the Touch ID sensor?

Sometimes the iPhone 5s has problems reading a fingerprint. The Touch ID system can be sensitive to moisture, lotions, oils, sweat and dry skin. Activities can also temporarily affect fingerprint scanning, such as swimming, showering or exercising.

To ensure the Touch ID hardware works properly, make sure your finger and the iPhone 5s home button are clean and dry.

To clean the Touch ID sensor, use a clean, lint-free cloth to wipe away dirt or debris from the surface of the home button.
