Washing machine rinsing. Woman following wartime instructions to drain and rinse her washing machine. Home maintenance was necessary because US domestic washing machine production was suspended after the USA entered World War II in 1941. This was to allow industry to switch to manufacturing war materials. The attached mangle (wringer, centre left) was used to squeeze excess water out of wet clothes after a washing cycle. This photoshoot, in February 1942, was by US photographer Ann Rosener (1914-2012), part of her wartime work for the Office of War Information and the Office for Emergency Management.
