Play-Doh was originally sold and used as a wallpaper cleaner⁠⁠. The company making Play-Doh, then called Kutol, was mainly producing soap, until the supermarket chain Kroger ordered wallpaper cleaner, a common product at a time where households were heated with dirty coal, from them in the 30s. They started producing the clay-like cleaner, and it soon became their main product. However, the use of wall cleaner declined greatly by the time the 50s arrived. That’s when employee Kay Zufall came in: she had seen a magazine wallpaper cleaner used as a material for kids to model Christmas decorations. She suggested selling the dough as a creative toy for kids. They removed the detergent in it, added colouring and an almond smell, and finally marketed it as Play-Doh.
