Who wouldn't want to use something called "fabric softener" in their laundry? Based on the name, it simply makes your clothes softer and cuddlier, which sounds irresistible.
Fabric softeners, however, contain undesirable ingredients, such as fragrances and dyes, which can irritate skin and cause other health problems. Plus, they can build up in clothes over time, which ultimately reduces clothes' longevity.
The sole purpose of fabric softeners is to eliminate static cling, but there's a much better (and safer) method for reaching this goal. Make your own irritant-free fabric softener just by using 1/4 - 1/2 cup vinegar in your wash water. You can add the vinegar directly into the liquid softener cup, if your machine has one, or add it on top of the clothing during the rinse cycle. Now you can be soft and cling-free without having to worry about side effects.
