Soak is a gentle, environmentally friendly cleanser for your delicates. It never needs rinsing, so there's less handling of your fabric and less wear and tear on your garments. I use Soak for all my lightly soiled handknits, especially those made with plan-based fibers. I also use Soak at home in the washer for my lingere. It's safe for all handwashables. Did I mention no rinsing? Love that. Plus it smells REALLY great.
