Soap is something that helps us stay clean and healthy. When you get really dirty and have a lot of germs on your hands, using soap and water can help get them off. Soap works with water because it has special molecules that are attracted to the germs and dirt, so it can help to lift them off your skin. So when you use soap and water, the soap helps to grab onto the germs and dirt and takes them away when you rinse them off.
