I clean my MacBook Pro keyboard daily (or almost every time I use it) with either water only or if it’s really yucky, a ~30% isopropyl alcohol spray.
I use a regular yellow microfiber towel (usually from the giant bag I pick up from Costco every few years)
Afterward I use it to wipe off the screen.
Personally I’ve never had any issues with screen coating except on the older 2012-2015 MacBook Pros where my fingernails eventually caused the coating to scratch by the webcam (when opening the display, I suspect)
A note about new microfiber towels: they need to be washed prior to use or they’ll leave little bits of plastic micro fibers all over whatever you’re trying to clean
Most of the time plain water and moist microfiber towel will make it look new again.
It does nothing for wear on the keycaps though my command key and a few keys like A, Z, W, and S are wearing away and look slightly glossy.
Interesting fact: you can use the other Thunderbolt port and a regular Thunderbolt cable (with the Thunderbolt 2-3 adapter) instead of the permanently attached one (the one with the MagSafe power cable) so there’s less stuff dangling.
My (somewhat weird) roundabout way is to take a deep breath in and exhale slowly while imagining myself at a time (like say 5 minutes ago) when I did not have hiccups, but it requires concentration (usually 5-10 seconds).
This is just my experience, but I had observed a wild temperature difference at idle and load on two identical MacBook Pros.
I’d already recently (within days) replaced the thermal paste with the same paste but still one of them was getting 10-15 deg C hotter.
The one that was cooler had been through AppleCare and it appears the copper surface had been scratched up intentionally as well as some dents on the fins.
The worse performing heat sink looked immaculate aside from some dust over the years. The copper surface was polished smooth.
Just for the heck of it I swapped the heat sinks and now the temps were reversed.
In the end I figured maybe the heat pipes were damaged or there was some performance differences of the heat pipes during manufacturing.
