To maintain the thinness, there is a single layer of glass and the LCD is glued to the underside of the glass. The older MacBooks had a double layer of glass. No plastic.Is the outer-most layer of my 2012 Retina screen glass por plastic?
https://support.apple.com/en-ca/HT204172And how should I clean it?
To reduce glare the screen is treated with an anti-reflective coating like glasses have. So the way you clean the screen is gently and therefore it will look good for a long time. If it always looks smudged they you likely have eroded the coating in a few spots. Replacing it will be expensive (everything from the hinges upwards is replaced), but also the coating should go away by itself over time. As was mentioned, you can "encourage" the removal: https://www.ifixit.com/Answers/View...problems+-+looking+for+quick,+viable+solution.The reason for my question is that whenever my Retina is off, the screen always looks smeared
"The reason for my question is that whenever my Retina is off, the screen always looks smeared, even though it always sits on my desk at home and I don't believe I ever touch the screen.
So what is the deal?!"
Sounds like "StainGate" to me.
You used Windex on it?
Possibly with ammonia?
In that case, no wonder it's smeared!
The retina displays have a very VERY thin anti-glare coating that is sprayed onto them.
This coating is very fragile by nature. It's easily damaged, moreso in the earlier versions of the coating (such as on the 2012).
Hence, the origins of StainGate.
Apple has (had?) a program of free screen replacements for StainGate, but a 2012 may no longer be covered.
The best way to "maintain" one of the retina displays is to "clean it" AS LITTLE AS POSSIBLE.
DON'T "wipe" it with any pressure.
Just "dust across it" with a soft cloth.
If you get something on it that won't "dust off", then use some water and a moist area of cloth, using as little pressure on the surface as you can get away with, then dust it dry.
Try to avoid touching the surface of the display, particularly when opening and closing the lid.
That's worked for me for 3 years with my 2015 MBP. No flaking.
If the anti-glare coating is already damaged or partially flaked off in some locations, there's NO WAY to "restore it" other than replacing the display.
Some folks have actually "rubbed off" ALL of the anti-glare material as a last resort. The end result is a glossy display, but with no "smears". I would try this only if it was really bad.
I assumed it was glass like my old MBP...
- Don't use aerosol sprays, solvents, or abrasives. (Windex is based on ammonia, so it is a solvent)
A clean microfibre cloth (or better yet the glass versions that don't leave bits of the cloth fibres) lightly dampened with water has served me well for 6 years to get rid of smudges, dust, etc. If you need Windex levels of strength then you should stop eating so close to the screen.

"Would I have to get a whole new screen/display?
Like how much to get it fixed?"
Take it to a brick-n-mortar Apple Store genius bar (NOT to a "3rd-party provider").
They -might- cover it under the "StainGate" screen replacement program.
I WOULD NOT tell them that you used Windex on it. They may deny warranty coverage if you do.
If they make you pay, expect to pay $700+/- for a replacement screen.
It's on the vintage list. I wouldn't expect that. Either it falls under a repair program or they're likely to offer depot repair, which is more like half that and covers anything that needs to be done overall. I'm not sure I would invest too much in a 2012 model, as you don't know how much life is left in it.
Never knew there was a formal list and classification for this.
I will have to check with my local Mac store and see what they can offer.
As to your comment, "I'm not sure I would invest too much in a 2012 model, as you don't know how much life is left in it."
Last I heard, Apple build CRAP laptops...
My fear is that the two Retinas I have may be the last usable Apple laptops - if not the last manufactured laptops ever. ;-(
Yeah I'm not a fan of the butterfly keyboards at all, and I had a terrible time dealing with them last time I owned an Apple laptop.
The 2012 models are likely to hit the obsolete list in the next year or so, as it will be seven years since they were last manufactured. At that point, your repair options are limited to diy solutions or third parties. Commenting on the age, I'm just saying that things may start to fail at this point, regardless of how you use it, because it's an old laptop.
In your situation, I would probably just live with it, but that's me. I have a pretty high tolerance for stuff like that on older gear.
Would you rather have a new 2020 Retina or my 2012 Retina?
