Recommended Cleaning Materials and Tools

Choosing the right cleaning materials is essential to avoid damaging your iMac screen. Using improper products or tools can cause scratches, streaks, or even damage the display’s protective coating. Below are the recommended items for safely cleaning an iMac screen:

  • Microfiber cloths: These are soft, non-abrasive, and excellent for removing dust and fingerprints without scratching the screen.
