At Purl Soho we hand-wash and block everything with Soak cleansers. Super gentle, phosphate free, and fiber-friendly, Soak also softens fibers and doesn't have to be rinsed out! It's great for needlecrafters of all kinds, as well as people who hand-wash their clothes. Soak Yuzu smells like a fresh kiss of tart citrus and crushed eucalyptus, while Soak Scentless is clean and fragrance-free for people with sensitive skin or noses! Soak is made with plant-derived and renewable ingredients, without sulfates, silicones, SLS or SLES and stored in completely recyclable packaging. Nice!
