The cleanest housekeeper I know is a cheerful and bantering French woman who says she isn't happy unless she's doing a "nettoyage profond." (For fun I call that profound cleaning.) The translation is "deep cleaning." I interpret this to mean that for her its spring cleaning every day of the year. À fond.
Do people think like they clean, or clean like they think?
faire le ménage: to do the housework; also to clear the decks, to clean up
nettoyer à fond: to clean deeply
à fond: in depth, thoroughly
