1 bottle lasts a long time! Love this detergent for either hand washing items or pre-soaking some really dirty things before machine washing. Helps lift the dirt, sweat and grime off and into the soaking water. Keeps clothing soft. They make unscented now but The scented ones are actually really light and don’t bother me like detergents often do. I use for underwear, bras, workout items, delicate sweaters, silk etc and now even for my kids’ extra dirty sports and camp clothes For handwashing it says no rinsing needed but I always rinse. For really dirty items I will do a couple rounds of soaking. LTKKids LTKmomlife LTKHome
