Despite your best efforts, as your MacBook often moves with you, it is bound to get dirty for a variety of reasons. Their moving nature means that fingerprints and smudges on a MacBook screen are fairly common problems encountered by Mac users. So when screen grime and blurring start to get too much, it’s a good idea to wipe it clean to maintain the best possible image quality.
Before you begin, make sure you are not using abrasive materials, whether it is the cloth you are using or the liquid. Apple warns you to do not use any of the following cleaners: anything that contains “acetone, glass cleaners, household cleaners, aerosol sprays, solvents, ammonia, or cleaners containing hydrogen peroxide”.
Here is the correct way to clean your MacBook or other Apple-made screen.
How to properly clean a MacBook screen
1. Turn off your Mac and make sure the power cord and all accessories are unplugged.
2. Dampen a clean, soft, lint-free cloth with water and wipe the screen. Do not spray directly on the screen as the liquid may cause damage if it enters the display.
3. Let any remaining moisture dry before plugging in your MacBook or turning it on.
How to clean other Apple screens
These instructions are quite similar to the previous ones and apply to iMac computers and other external displays made by Apple.
1. Turn off the display (in the case of iMac, turn it off). Make sure you unplug the power cord and all attached accessories.
2. Use a clean, soft, lint-free cloth to remove dirt or stains.
3. If the above proves insufficient, moisten the cloth with water and repeat.
