The fascinating thing about cleanliness is that it is mostly in the head. A peppermint tastes fresh; clean windows look clear; and there’s nothing better than the lovely feeling of slipping into a freshly made bed after a hot shower. We like the smell of clean things. We like to run our hands over smooth, polished surfaces. We find comfort in the idea that we are protected from an invisible world of germs if we use enough disinfectant.
