How to clean off keyboard marks on screen?

If you are very lucky it is just dirt and can be wiped off but usually it is permanent and there isn't much way to avoid them. I have seen it happen even when a soft cloth is used to cover the keys when the lid is closed. In fact that may even make it worse as the cloth adds thickness to the sandwich and may make the contact between the high points of the screen and the keys firmer. The screen surface of an anti-glare display just isn't very hard - glossy glass is harder but can still be marked.

Using a quality micro fibre cloth with a 70% water/30% isopropyl alcohol solution is a good way to clean the marks off if they are not permanent. I have been using the cleaning solution provided by my optician for my glasses for years with no ill effects, and I love the iKlear blue microfibre cloths (for both glasses and displays). They call it "terry" as opposed to their "chamois" cloth.

The MacBook Air keyboard shouldn't be touching the screen when it's normally closed. This only happens when you've put the computer under pressure when it's closed. For example, maybe you put it in a backpack with heavy books surrounding it and putting pressure on it.

About whether they're permanent, it depends on how "etched" they are. If you try a moist, soft cloth and rub the screen gently for about a minute, and they don't come off, then unfortunately they most likely will not ever come off. If you're still under AppleCare, they might fix this for you.

You can prevent this from happening in the future by putting a very thin cloth between the keyboard and the screen when you sleep it. Also, try not to put pressure on the computer, then it won't happen in the first place.

I have MBP 2017 without touch bar. I usually cary it with Thule case which I am sure it does’t put pressure on my MBP. I have tried many solution to wipe the marks off still having marks of the keyboard’s edge on my screen and it seems permanent.

The short answer is you can't prevent these marks.

It's a design flaw. The screen doesn't have enough clearance, is in contact with the keyboard when closed, and gets marked.

My current laptop is a MacBook Pro 16 I bought in May, about four months ago, and noticed key marks on the screen straight away. I bought screen cleaner and a microfibre wipe, and with prompt cleaning can see marks appearing regularly.

I have a (Bellroy) sleeve to protect the laptop, and transport it in a dedicated bag that is very lightly loaded; just an A5 notepad, water bottle, and small zip case for cables.

The good news is that this is a known issue at Apple. I opened a support request yesterday, during which the rep acknowledged Apple recognizes this problem, and was offered service.

My previous laptop was a MacBook Pro 13, which I kept for five years due to waiting out the the butterfly switch fiasco.

The 13 inch laptop had the same issue, and over time the key marks became permanent, as sweat, debris, oils, etc on my hands would have degraded the screen coating over time.

My 16 inch has the extended warranty, and I am going to just use as normal keeping the screen and keys as clean as possible. I'll take it in for service & get a new screen just before the warranty expires. Hopefully I can avoid any permanent marks in the interim.
