A simple rule, but full of common sense: “If it’s yellow, we wait.”
In many households concerned about their ecological impact, a small, common-sense rule has become essential:
“If it’s yellow, we wait. If it’s brown, we bring it down.”
Translation: No need to flush every time you go to the toilet. Urine is basically sterile and poses no danger if the toilet is cleaned regularly. So, all you need to do is adopt a consistent cleaning routine , with a quick brush and a little product every now and then, and you’re good to go.
