In this episode, we scrub up the origins of cleaning-related words. The English towns of West Bromwich and Castle Bromwich share an etymology with a term for sweeping floors, while laundry has roots connected to lavatory. The phrase spick-and-span is believed to have nautical origins, just like the word squeegee. Learn who invented the vacuum cleaner, which was originally referred to a suction sweeper, and who bought the rights to it.
