Follow the instructions on the care label of the garment.
Professional Dry Cleaning is recommended for most of the garments but one can easily wash silk at home if the stain is light to moderate.
Silk colors can often bleed. Perform a color fastness test using a cotton swab dipped in liquid detergent. Dab the swab on hidden seams to see if any dye comes off. Bright prints and colors that bleed should be dry cleaned.
For Washing: Fill a tub or sink with cold water and add a small amount of delicate-friendly liquid detergent. Lightly agitate for 2-3 minutes and rinse well. Continuous rubbing of a single spot can cause color lightening. Washing the entire garment is advised.
After rinsing, squeeze the excess water. Never twist or wring out silk garments/fabric, doing so can damage the fabric.
Avoid the dryer and lay wet silk garments under shade onto a clean, absorbent towels to get rid of excess moisture. Use multiple towels and then lay flat on a drying rack of towel.
If fabric care labels say the garment can be ironed, then iron on a low setting while the garments are still damp.
