Edit:
I realize I didn't answer your question the first time so I'm back haha.
Two years ago I asked an Apple store employee what they used to wipe down all Apple products because everything was so clean. Like no fingerprint stains on any of the keyboards, immaculate iPad and iPhone screens.

He told me they used "Whoosh" cleaner and microfiber cloths, both available on Amazon.

I've used Whoosh on my own Macbook Pro and indeed it cleaned my screen effectively, but I haven't needed to use it on the keyboard since I use keyboard covers. Also, this was on the 2015 Macbook Pros. Ymmv since we're now talking about the 2017 MBPs, but if you ever stop by an Apple store, you can always ask them what they use - or if they use/ever used Whoosh.

If you don't mind the frosty look on your keys, I'd recommend a keyboard cover. I've used one on my Macbook Pro 13 2015 since the launch week and buy a new one every half year or so for cleanliness reasons.

In my limited experience, a brand called Uppercase has pretty consistent quality. Good luck!

I thought this was the stuff they used - https://www.amazon.com/gp/product/B00DOPW5L0/ref=oh_aui_detailpage_o01_s01

Over used WHOOSH! screen cleaners for a year and I really like it.

Saw them at CES last year, they gave me a free sample, and I liked it so much I bought them. They're pretty legit.

I've been using whoosh screen cleaner. It's supposed to clean with out harsh chemicals. It seems to work well for me.

Woosh and a microfiber cloth (specifically a cloth that came with glasses). https://www.amazon.com/WHOOSH-Award-Winning-Screen-Cleaning-Antimicrobial/dp/B00DOPW5L0
The good thing about Woosh it's antimicrobial and nontoxic. It's perfectly fine for lenses, but 99.9999999% of the time, I simply just wipe the lenses clean. Even though Woosh has no ammonia, alcohol and is completely safe, I find wiping the lenses with a lens cloth work perfectly fine.

I bought some Whoosh and it's worked very well to clean my screen. I still smudge as I use it, though.
