Shoe polish is a product used to clean, shine, and protect leather footwear. It typically comes in a paste, cream, or liquid form and contains waxes, dyes, and oils. The primary purpose of shoe polish is to restore the appearance of shoes and extend their lifespan by providing a protective layer against dirt and moisture. Applying shoe polish involves cleaning the shoes first, then using a cloth or brush to apply the polish evenly. After allowing it to dry, buffing the shoes enhances their shine. Regular use of shoe polish can help maintain the quality of leather, making it look new for longer.
