Isaac has a 2015 MacBook Pro and the anti-reflective coating was flaking off. Apple said there was a recall and they replaced it for free. Leo says he'll have to be careful not to use alcohol-based cleaners because those will strip off the coating. Leo recommends Screen Guard Foam Cleaning Spray.
Leo also says to get a microfiber cloth that's the size of his trackpad. That's important because, without it, the trackpad will strike the screen and make an outline. So he should cover it to protect it.
Another good idea is to get a screen protector. He could get the Moshi iVisor Anti-Glare Screen Protector for MacBook Pro on Amazon. There's also this two pack of anti-glare screen protectors from ANTOGOO on Amazon for about $15.
