As a general rule, linen clothing can be machine laundered on the delicate or short cycle with a cold water wash and rinse.
You will extend the life of the fabric if you hand-wash your linen clothing in cold water.
Steer clear of harsh laundry detergents when washing linen clothes.
Buy a mild detergent formulated for delicate fabrics. Always remember to separate your whites and colors—new linen dyes have a tendency to bleed in the wash.
