If you are trying to go green this is an essential product. Dr. Bronner’s is the most commonly known and readily available and has a variety of formula’s. If you see just plain Castille soap in my mind that is the best to keep in your pantry because of it’s versatility. I got this large bottle at Whole Foods for about 10 bucks. The scent is nice an neutral and you don’t need a lot of product to get the job done.
