Shoe polish (or boot polish), is a waxy paste, cream, or liquid used to polish, shine, and waterproof leather shoes or boots to extend the footwear's life, and restore, maintain and improve their appearance.Various substances have been used as shoe polish for hundreds of years, starting with natural substances such as wax and tallow. Modern polish formulas were introduced early in the 20th century and many of those original formulations are still in use today. Today, shoe polish is usually made from a mix of natural and synthetic materials, including naphtha, turpentine, dyes, and gum arabic, using straightforward chemical engineering processes. Shoe polish is usually flammable, can be toxic, and, if misused, can stain skin. It should be used in a well-ventilated area with care taken to protect clothes, carpet and furniture.The popularity of shoe polish paralleled a general rise in leather and synthetic shoe production, beginning in the 19th century and continuing into the 20th. The World Wars saw a surge in demand for the product, in order to polish army boots.
