I have to tell you, 4am-5am, between sleep phases, is the best time to clean a kitchen. It's vaguely contemplative and when you go into the kitchen later that day it's like the cleaning fairy did it.
So some tasks you do in that period of time are done with a kind of lower level of objection, easier "starting", and in a contemplative start, and you're not actually tired.
Which is what also gives this "cleaning fairy" sense that nobody in particular did it.
