The standard way to clean clothes in 1956 is by using a wringer-type washing machine, such as the Kenmore "Visi-Matic" model advertised here. It comes equipped with a "Roto-Swirl" agitator and "sparkling glamorous chrome-plated" wringer.

The more up-to-date (and affluent) 1956 housewife will probably be looking to buy a laundry pair like these Kenmore machines. The "Hydro-Swirl" automatic washer features a "Retro-Swirl" agitator.
