The surface of the display has a sprayed-on thin anti-glare coating.
It's VERY fragile, and easily damaged.
You don't want to "clean" it any more than absolutely necessary.
A "dry wipe" may be THE WORST THING you can do to it.
The coating may begin to flake off -- and then you have "StainGate" (look it up).
My suggestions:
DO NOT routinely "wipe" the surface of the display.
Try to avoid touching it at all, particularly when opening and closing the lid.
If there's dust on the surface, use a soft cloth and gently "dust it away" (without pressure).
If there's something on the surface that won't "dust away", use a moistened cloth and AS LITTLE PRESSURE AS POSSIBLE to dislodge it.
Then, dry the surface by "dusting" as above.
When the sprayed on anti-glare surface was first introduced on the retinas, it was very susceptible to problems. Apple seems to have "toughened it up" somewhat since then, but I would still be careful with it.
Personal experience:
I have a 2015 MacBook Pro 13".
I "practice what I preach" above, and the surface of the display is still without problems.
