Initially, they were actually made of wood (even the ridges). Later on, they made the 'scrubbing' portion of the washboard with zinc. This was the main metal used up until the tail end of the 20th century. At that point, galvanized steel was the metal of choice. There are some washboards made with brass as the ridges, but they're not quite as common as the galvanized steel.

What is the history and significance of washboards in music?
Washboards have been used as musical instruments since the late 19th century, particularly in American folk and blues music. They were originally repurposed from household items and played by scraping a metal object, like a spoon or thimble, across the ridges of the washboard. The unique sound created by the washboard added a rhythmic and percussive element to music, often accompanying string instruments like the guitar or banjo. Washboards became a staple in jug bands and skiffle music, contributing to the distinctive sound of these genres. Today, washboards are still used in various musical styles, preserving their historical significance in the evolution of American music.
