Hang-dry in the shade
Silk is fast drying, thanks to its ability to transport moisture. Avoid hanging your silk garments in direct sunlight, it can bleach the fabric. Also remember to never tumble dry your silk garments. Read more about sustainable drying methods here.
Be quick to remove spills before they stain your garment. Rinse with cold water and rub the stain gently (from the inside) with laundry detergent or bile soap if needed. Acetone or chemically pure petrol can be used on grease stains. Be careful and try it on a discrete spot before treating the stain, you don’t want the chemical to ruin your fabric. The most important thing is to act at once and not wait until your next laundry day. Please note that most stain removers found in stores should not be used on silk fabrics.
