Water supply can contain hard water which contains a lot of minerals and metals such as calcium and iron. When one is using water for cleaning, it is difficult to use hard water because soap doesn’t lather easily.
Water softeners are used to convert hard water into soft water. A water softener is used in hard water to dilute mineral concentrations or remove concentrations.
Water softeners enable easy cleaning because clothes can be rinsed thoroughly without leaving any soap residue. Clothes that have been washed with soft water normally last longer.
Soft water is good for cleaning because one does not have to use a lot of soap in order to clean clothes and items. Water softeners eliminate soap scum on surfaces. The use of water softeners eliminates the film that is left behind when one uses hard water.
