Origin of “Wipe the Slate Clean”
This idiom goes back to the 18th century, when people used slates (small boards) to write on with chalk before paper became common. When you made a mistake, you could simply wipe off the chalk and start again—leaving the slate literally clean.
By the mid-1700s, this simple action became a metaphor for starting over in life or relationships. It captured the satisfying idea of erasing old errors and giving yourself (or others) a second chance.
So, while we no longer use chalk slates in daily life, the phrase has stuck around because the feeling of wanting a clean start is timeless.
