i was given a small bottle years ago and loved the smell and how long it lasted, ran out , %26 knew i had to order another, bigger one. Zum is completely different than detergent.. it's low foam with essential oils for a very appealing aromatic smell. i love the Seasalt one .. its a blend of patchouli and citrus and other oils, giving your clothes a beautiful smell that lasts %26 makes the home smell amazing! i love it %26 there isn't anything out there that compares to it ! Will continue to purchase once this bottle gets low !
