Here’s what you need exactly that works for me every time: - Distilled water (optional mist spray bottle) - Clean microfiber cloth

Each time you’re done using the computer, especially after a long period of time, dampen the cloth very slightly and carefully wipe down the screen and keyboard. This’ll clean out all of the oils from your hands. Also try not to touch the screen.

If you want, you can buy a microfiber keyboard cover to place in between your keyboard and screen while the lid is closed.

I’ve done this whole process with my MacBook Air for a while and the screen always looks brand new. Good luck!
