How can I effectively clean refrigerator shelves to ensure they are free from dirt and bacteria?

To effectively clean refrigerator shelves and remove dirt and bacteria, first remove all items from the shelves. Wash the shelves with warm, soapy water and a sponge or cloth. Rinse thoroughly with clean water and dry with a clean towel. For tougher stains or odors, use a mixture of water and vinegar or baking soda. Make sure to clean the entire surface, including the edges and corners. Regularly cleaning and sanitizing refrigerator shelves can help prevent the growth of harmful bacteria.
