We recommend hand washing silk clothes by turning them inside out and submerging them in a basin of water mixed with 2 or 3 capfuls of this product. Gently agitate the water and leave your clothes in it for 15 minutes (don’t leave them longer than 30 minutes). Rinse thoroughly with fresh water, and don’t be alarmed by any colour left in the water - that’s normal. If you want to use the machine, pour 2 to 3 capfuls into the drawer and wash on a delicates setting. PS - if the label says ‘dry clean only’, washing them is at your own risk.
