Eucalan Woolwash is concentrated, so it only takes 1 tsp. per gallon of water (you can use more for heavily soiled items). Use it to wash by hand or in the machine using tepid water and avoiding heavy agitation. Its enriched with lanolin, so it helps the wool regain some of its original softness and relaxes the fibers. Before using any wash, test for colorfastness. Original scent (Eucalyptus).
