For sysadmins, that is. (automation, robustness etc.pp.) For people in solo households (like me) it's not so definite.

I dislike cleaning, but I like it when the house is clean. Specifically, I dislike scrubbing the kitchen sink/washbasin strainers and their surrounds: always somewhat grotty and lots of brushing required to keep them nice.

But yesterday I found out that there's a super-lazy solution for that: put in the stopper, pour in some bleach, let it stand for an hour or so, then unstopper the drain and you're done. Results were shiny and dirt-free.
