Wow, I’ve had my machine for less than a year, and the keyboard looks like it’s 10 years old. See pic of wear stains. Tried cleaning, does not come out. Possibly a poor quality material problem. Not expected from apple products :(
Comapre that to my old 2013 MacBook Pro (which I used very heavily).

I've seen that with some Apple laptops for a long time. I don't know if it is due to the key caps themselves, or perhaps the oils or lotions on people's hands....it may actually be both. The differences may be due to Apple using different manufacturers for the keyboards (Apple tends to source most components from two different vendors).
If the laptop is still under warranty, then have Apple examine it to see if they will address the issue under warranty (doubtful, but doesn't hurt to try). An Apple Store is probably best since AASPs are unable to make exceptions to Apple's official rules. If Apple won't address the issue under warranty or if the laptop is out of warranty, then you can provide Apple with product feedback here (Apple won't respond):
You can also contact Apple corporate (Apple may respond):

You can also check out your local consumer protection laws.
I have had very good luck wiping the "Stains" away with a micro fiber cloth sprayed with a bit of 409. Allow the 409 to soak into the micro fiber cloth before using to wipe the keys and I turn my machine off while doing it.
