Sink cleaning involves the process of removing dirt, grime, and food particles from the sink's surface. Regular cleaning helps prevent the buildup of bacteria and unpleasant odors. Common cleaning agents include dish soap, vinegar, and baking soda, which can effectively break down stains and eliminate odors. To clean a sink, start by rinsing it with warm water. Apply the chosen cleaning agent, scrub with a sponge or cloth, and rinse thoroughly. For stubborn stains, a paste of baking soda and water can be used. Proper sink cleaning ensures a hygienic kitchen environment and prolongs the life of the sink itself.
