Step 1: Don't not flush toilet.

Isn't it about moistening the surface of the bowl above the waterline, which would probably otherwise be dry hours after the last flush?

Europeans often keep shit in their toilets for two reasons: Living in a multistory building and not annoying the neighbors downstairs during the night; and saving water. It’s absolutely disgusting, but such people also don’t usually wash their hair (and I mean, engineer-type people, not necessarily unemployed kind).

Ooooooohhhhhhhhhh.

I often thought: It seems like flushing first makes much of the cleaning product run right into the water rather than sticking to the bowl, but there must be a reason they say to do it.
