In 1882, an Indianapolis chemist noticed how clean and shiny his tarnished pot was after cooking rhubarb. Using an active ingredient that’s found in the plant he formulated a talcum-smooth cleanser and sold it to the city’s taverns. So pleased were his customers with how well it worked on bar fixtures, the product was dubbed the “Bar Keepers Friend.” Today, Bar Keepers Friend is still made in Indianapolis and is found at retailers across the United States and in many other countries.
