Soak is Modern Laundry Care, for the laundry you love. Soak Wash is great to use on your Sloomb wool! Though the bottle says it is a "no-rinse" wash, when using our wool for cloth diapering purposes, Sloomb recommends rinsing the wool under running water after washing. If using Soak Wash on wool that isn't used for cloth diapering purposes, and won't be lanolized, rinsing is not required. Soak products are manufactured in Toronto.
