For the record... This is the FIRST ever I'm reviewing something on the first day! This stuff smells amazing! And all I've washed so far with it is my hands! Got it, (after an 8hr shift of work) and washed my hands with it, sitting outside 80 degrees with a breeze and I keep getting a wiff of it. Smells amazing like I'm wearing a cologne! My wife noticed and asked why I was wearing cologne. Highly recommend
