Dish soap, also known as dishwashing liquid, is a cleaning detergent specially formulated to remove grease, food residue, and stains from dishes, utensils, and kitchenware. It produces rich suds that help lift dirt and oil for easy rinsing, leaving dishes clean and shiny. Most dish soaps are gentle on hands, have a pleasant fragrance, and are effective even in cold water. They can be used for hand-washing dishes, cleaning countertops, and other household cleaning tasks.
