Turtle Wax

Turtle Wax is an American manufacturer of automotive appearance products. The company was founded by Benjamin Hirsch in Chicago in 1941 and is currently headquartered in Addison, Illinois, having relocated from Willowbrook, Illinois in 2016.
Hirsch's main product, a liquid car wax, was initially called Plastone, until Hirsch changed the product name to create the association with a turtle's hard shell. Hirsch died in 1966 and successive generations of his family have remained involved with the company. Its advertising jingle ("Turtle Wax gives that hard shell finish"), created early in its history by the Doner Company, became very well known.
Turtle Wax is the largest automotive appearance products company in the world and distributes its products in more than 90 countries.

Turtle Wax has marketed its cleaning products for non-automotive applications, as well.
Turtle Wax also offers automotive performance chemicals such as engine treatment products and formula oils under the Marvel Mystery Oil and CD-2 brands. Additionally, the company operates full-service car wash facilities in the Chicago Metropolitan area.
