There are two different possible methods you can use when it comes to using Epsom salts as a fabric softener. First, if you have a top-loading washing machine, you can fill the basin with water and a generous scoop of Epsom salts. For those with front-loading machines, you can still try this in the bathtub. Allow the sheets to soak in the saline solution for at least a few hours — the longer the better. After they’ve absorbed the salts, add the sheets to the washer and wash them on your usual bed linen setting.
You can also just toss Epsom salts into the washing tumbler like you would a powdered detergent or baking soda. Add about 1/4 cup of salt to the washing load and make sure the water is warm enough that the salt can actually dissolve in the process, or else it can cause mineral buildup in your machine. If you find yourself missing the smell of store-bought softener, consider adding Epsom salts to a jar with a few drops of your favorite colorless essential oils. The all-natural fragrance will meld with the salts and leave a pleasant aroma on your laundry. And with this method, you can have a natural fabric softener ready to go at all times –one that just so happens to be able to double as a bath soak!
