Lanolin-Free Wool Wash
Works well on other woolen or blend fabrics... even favorite stuffed animals.
Draw a tepid/warm bath for your knit wool or hand-wash wrap items, and add 1-2 tablespoons per gallon of water. Gently soak your items, then remove and rinse & lay to dry as usual. This wash contains no added surfactants, so it is low foaming/sudsing-- do not be fooled by minimal suds, it is working. Can also be used in the machine for any machine-safe textiles.
