My Retina Display has stain damage, HELP!!!

I dont know how it happened, but somehow my retina display got some weird clear-ish stain damage that is very noticable on a black background. I have tried to clean it with water and a micro fiber cloth like usual, but i think this is not something on top of the screen as much as it is something has like eaten away a part of the screen... I need help! what do i do to solve this aside from replacing the screen... if water and microfiber arent working, what else can i use? I am worried that windex or alcohol will excacerbae the problem, as i suspect it might have been alcohol that caused the problem in the first place, but im not sure... any insight, please? this is driving me nuts

Yes,  There is no that can recoat a glass display while attached to the display assembly.

That coating is applied in a vacuum chamber , you cant "recoat" it, and if you could, which you cant, it would look horrible and not stick.

You can only apply said coating on NEW sterile displays in a vacuum chamber.

You can only see that damage on your display if its in a well lit room / outdoors......., in a dark room I dare say I bet you cant see the 'damage' at all.

those are keyboard key marks from finger oils transferred to the screen.

Thats 200% as clear as day.

something has like eaten away a part of the screen.

Yes, acid on your fingers (and oils) transferred to the keys, THEN to the display when closed.

but somehow my retina display got some weird clear-ish stain damage

No.........thats stripped AR coating FROM the screen,  not  ON THE SCREEN.

Youre thinking its something THERE, when its something MISSING

I am worried that windex or alcohol will excacerbae the problem,

Dont dare use that, that will ruin your screen.

if water and microfiber arent working,

They wont work, because your hand oils and acids have stripped the AR coating off part of the screen. Keep cleaner hands when using your Mac.

Some people have naturally VERY HIGH acidic skin excretions,  you may have this issue.

so, if its that clear that my finger oils have stripped away the AR coating from the screen (what is AR, btw?) what do I do to fix this... if I am not torying to remove a smudge and am instead dealing with something missing, as you said, what can be done to remove the appearance of the spots? its really really really annoying!

You cant fix it, its the display assy.  You either live with it or have the display removed and replaced.  However it will occur again immediately if you are one of those rare people that excretes very acidic skin oils.

There is nothing to REMOVE, what your looking at is what is MISSING.    Its been removed already

I used to fix computers for years, and have years of experience in an optical shop messing around with AR coatings.  skin acids and oils strip the antiglare crystaline coatings.

whats left is the glass substrate and screen reflecting back normally as bare glass does.

If you look closely at your picture, you can see its a mirror image of your keys, and negative image of your trackpad.

Ive seen this before many times.  9 times out of 10 its someone that has very acidic skin excretions left on the palm rests and keys that transfers to the screen, which THEN strips off the AR coating.

You can also EASILY see there are more oils / spots near the top edge of either side of the trackpad where your palm rest and excrete the oils and acids.

See that purplish tint on your display??  Thats the AR (some call it anti-glare) coating.

You can stop this by using a very very thin piece of felt (VERY THIN) paper or plastic between the screen and keyboard.

so are you saying that the damage is permanent? as in, there is nothing short of replacing the screen that will fix this problem?

Thanks for your input... i appreciate the insight, though knowing that i need to replace my screen makes me quite upset. the weird thing is that i have had this computer for a year now, and this has never been a problem before... i think maybe someone else was using my computer and it is their finger oils who are the culprit.... arrrrrrghhhhhh this is going to drive me crazy. how much is it to get this fixed, do you know off the top of your head? thx again for your insight

You "think" someone else was using?

College I presume?   

Considering its the entire display assy. and its a retina display, it would cost A LOT.

This is the one rare time I would say,.... unless money is no concern at all to you,... not to consider it. Very expensive.

haha well not college but kinda... my computer was open at a bar where i work being used to play music and someone kept going up and changing the tracks and stuff... we serve burgers and burritos and fries so my guess is that their hands were just really greasy and i didnt think to wipe down the keyboard before closing it... trust me when i say i take good care of my machine and clean the screen regularly and i noticed this immediately after that night and now all my obsessive cleaning has been for naught.

this might be a stupid question, but would it be a bad idea to just like strip the entire AR coating from the display, so that its just bare glass? as it is, it looks really ugly and my ocd is kinda enticing me to just try to strip the rest of the coating off so at least it looks like consistent and not all cloudy/foggy/smudgy... i know this might sound lke a really dumb idea. please dont hesitate to let me if it is like the dumbest idea ever

it was not the grease that assaulted that AR coating, it was something acidic

drinks, condiments, etc etc.

ultimately then, soda pop acid and Katsup etc. beat your screen coating up with a stick.

Obviously never let other peoples have at your Macbook.

I knew you were going to ask that,  many people 'try', the results arent good, and usually WORSE

also that LCD is very fragile, you dont want to dare press on it (which you would have to do to remove the coating entirely).

If you try, it will go from "slightly ugly at an angle" to "always ugly"

and high possibility of LCD damage.

Plontius: would this do anything to improve my situation?

your screen is glossy with a no-glare reflective coating

that sheet-film is a transparent (of course) matt-luster film meant to stop, for example, overhead lighting reflection in an office, (most especially), sunlight or at home.

As is the case, and of course your picture above tells, in a darkened room I know you cant see your issue at all.

however with the right lighting you can, of course.

Additionally since your LCD is black, and you're not looking at a black screen at any time, then of course this also makes your issue one of 'irritating' rather than preventing you from using your macbook to its full extent.

Such a LCD film however could have protected it to begin with, but now the horse is out of the gate.

This damage is user induced,  albeit however, another user than yourself,.....as you indicated.

***!? Its growing!!!!

I have cleaned the entire laptop - keyboard, screen, everything - with a microfiber cloth lightly dampened with distilled water... I let it dry, closed it for the night, and when I opened it up this morning the AR coating is very clearly more stripped than it was yesterday... where it was once just one side of the trackpad and a couple keys on the left side before, the stripped layer has now grown to encompass the whole trackpad and the whole first row of keys.

Compare the first picture with the one above, and tell me it hasnt gotten bigger. I called Apple support, they have no idea what to tell me. This is wierd... Anybody? Anything? I am warranty-less, and am starting to think this has nothing to do with anything I did... My previous suspicion that random people changing the music while it was open at a bar is kinda fading... something else is at play here. 

Help please... my computer is dying of what seems like leprosy.

Compare the first picture with the one above, and tell me it hasnt gotten bigger.

Bit more, yes.   You should have used rubbing alcohol (isopropyl 70% and 30% water found at any drug store) on the palm rests around the trackpad  VERY LIGHTLY DAMP on a cloth.

being VERY careful not to get it into the seam around the trackpad  <<<<<<<< (very careful).

microfiber cloth lightly dampened with distilled water

water alone wont remove the oils and acids, the isopropyl however will.

you can use Qtips with same on the keys making sure NOTHING drips into the chassis.

its not warranty work, no, because its used caused (well another users as you said).

As stated earlier, soda pop acid and acidic / oily fingers were planted on your keys and around your trackpad.

I am warranty-less, and am starting to think this has nothing to do with anything I did......at a bar

drunk peoples with sticky greasy fingers touching your notebook.....etc etc etc.     That'd do it.

I have a very similar problem. I was told at the genius bar that the damage was caused by excessive pressure, and they refused to fix it under warranty, because it is not a manufacturing issue. I wasn't taking any special precautions (hard case, screen protector) and carry my MBPr in a neoprene case in my backpack with the other stuff. I wouldn't call the amout of pressure it was exposed to excessive, it's an aluminum body after all. Replacing the screen is ~1/2 - 1/3 of the price of a new machine...
