What household cleaning product was originally developed as a wallpaper cleaner before becoming a children's toy?

The familiar modeling compound known as Play-Doh has a surprising origin story that dates back to the 1930s. It was not initially conceived as a children's toy but rather as a practical household cleaning product. Developed by Kutol Products, specifically by Noah McVicker, this pliable, dough-like substance was designed to remove stubborn coal residue and soot stains from wallpaper in homes that relied on coal-burning furnaces for heat. Its unique composition allowed it to effectively lift grime without damaging delicate wallpaper.

However, the need for such a specialized cleaner began to decline significantly after World War II. As homes transitioned from coal to cleaner-burning natural gas and oil for heating, the prevalence of soot on walls diminished. Additionally, the introduction of washable vinyl wallpaper further reduced the demand for the putty. Facing potential bankruptcy, the company was searching for a new purpose for its product.

A pivotal moment arrived when Joseph McVicker, Noah's nephew, learned from his sister-in-law, Kay Zufall, a nursery school teacher, that children enjoyed using the soft, non-toxic putty for art projects. She recognized its potential as an inexpensive and malleable modeling material, even suggesting the catchy name "Play-Doh." Seizing this innovative idea, McVicker began marketing the product to schools in the Cincinnati area.

The product was quickly embraced by educators and children alike. In 1956, it was officially rebranded as Play-Doh and introduced to a wider audience at an educational convention. Its popularity soared after being featured on influential children's television shows, most notably Captain Kangaroo, which cemented its place as a beloved toy. Today, this simple compound of water, salt, and flour continues to spark creativity in countless children worldwide.
