Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
Softener may refer to: Fabric softener , a conditioner that is typically applied to laundry during the rinse cycle in a washing machine. Stool softener , anionic surfactants that enable additional water and fats to be incorporated in the stool, making it easier for them to move through the gastrointestinal tract.

Any products claiming to utilize magnetic water treatment are absolutely fraudulent. [1]
Cationic softeners are incompatible with anionic surfactants in detergents because they combine with them to form a solid precipitate. This requires that the softener be added in the rinse cycle. [6] Fabric softener reduces the absorbency of textiles, which adversely affects the function of towels and microfiber cloth. [7] [failed verification]
