Polishing of footwear, also known as shoe shining, is a process of cleaning and buffing leather shoes to make them look shiny and new. It involves the use of a brush, polish, and cloth to remove dirt and scuffs from the surface of the shoe and then apply a protective layer of wax or cream to give it a glossy finish. Shoe shining is an important part of maintaining the appearance of leather shoes and can help extend their life.
