One of the oldest known luxury natural fibers. The safest way to wash delicate silk garments at home is to hand wash with a specialist detergent in lukewarm water, without soaking as this can release some dye. Rinse the silk garment without wringing. To machine wash silk, wash at 30°C or lower, on a low spin using a small amount of detergent. A mesh bag can help protect silk garments from snagging or twisting too much in the washer. To dry, lay the silk garment on a towel and roll up the towel to absorb excess moisture. Then lay flat on a drying rack or hang to air dry. To iron silk, use the lowest temperature on an iron, or for an energy-efficient method, simply hang in the bathroom while taking a hot shower. The steam will reduce creases.
