Soap was made for cleaning washing and such. It’s important to use soap in the process of cleaning your clothes because not only does it usually leave a better scent but it helps take out stains and such. That’s why we use soap to clean our bodies, faces, dogs, certain materials. So that the dirt and any other debris comes off. Think about washing the dishes, you don’t wash them with only water. You use soap because it’s the most logical effective way to clean things.
