How to properly disassemble the keyboard area and clean it?

The keyboard is riveted to the uppercase and getting to it from the inside is quite difficult. Since you have such a new system I would leave things alone. Dust is mostly not the worry, liquids are! Clearly don’t use your system on the beach of eat food which is crumbly as this type of debris can also cause harm.

If you haven’t I would sign up for AppleCare+ That will give you a bit more protection if you are likely planning to go into a war zone or just have messy kids😎

Only use a lightly dampen clean towel with mild counter cleaner on the shell and keyboard surfaces, and for the screen straight water (distilled being best) on a lightly dampen clean towel and if the dirt is stubborn, add a little White Vinegar.
