When you wash in soft water, you feel your skin the way it’s supposed to feel, clean and silky smooth. According to the U.C. Berkeley Wellness Letter, when you wash in hard water, the soap you’re using reacts with the hardness minerals in the water “to form an insoluble residue that’s difficult to wash away.” The “squeaky” feel/sound many people associate with being clean is, in fact, your skin sticking because of this residue. Soft water rinses your skin and hair better than hard water and doesn’t leave a soap or shampoo residue behind. People that use soft water consistently enjoy the “truly clean” feeling they get when washing with it.
