Laundry Tips When Washing With Soft Water | Hunker
Some people add table salt (the main ingredient of which is sodium) to their laundry to prevent color bleeding or to help get their clothing whiter, but when you have soft water, you do not need to add as much. Instead of adding the usual cup of salt to your laundry, you may be able to use as little as one-third or half a cup of salt.
