Hand wash in cool to tepid water with mild detergent like Eucalan. Do not use detergents with brighteners like Wool Light, Tide, etc. as these degrade the fibers and cause color fade. Never use bleach. To help fix color and remove odors add small amount of white vinegar to rinse water. Avoid excessive manipulation or rubbing as this causes felting and shrinkage. Squeeze out excess water and lay flat to dry. Never dry in dryer.
