Bring the water temperature up to warm, add Lissapol ND Soap and wash by hand or in a washing machine. Run through a full cycle to complete the crucial after-wash. If the silk fabric contains a fair amount of light areas, use the Lissapol ND during the complete rinsing stage. This protects the fabric from loose particles of dyes. Use a capful of white vinegar in the final rinse to condition the silk and to aid in ironing.
Silk is best ironed wet with a warm iron.
