Historical information

A washboard is a tool designed for hand washing clothing. The traditional washboard is usually constructed with a rectangular wooden frame in which are mounted a series of ridges or corrugations for the clothing to be rubbed upon. For 19th century washboards, the ridges were often of wood; by the 20th century, ridges of metal were more common. A "fluted" metal washboard was patented in the US in 1833. Zinc washboards were manufactured in the US from the middle of the 19th century. In the late 20th century and early 21st century, ridges of galvanized steel are most common, but some modern boards are made of glass.
