For first three washes, dry cleaning is advisable for silks.
If ever silk is washed in water, ensure it is washed in soft lukewarm water using a good neutral soap only.
Squeeze lightly with hand to remove water after washing.
Always dry the silk in shade only on a flat surface instead of hangers.
Use low / medium heat while ironing.
Always iron silk on the reverse side.
Never spray water to dampen silk before ironing as it may cause water spots on fabric.
Do not wash stains with water, instead give it for dry cleaning.
The high demand for silk has led to serious distortions and malpractices in the silk value chain. Adulteration with lookalike fibres like Nylon, Rayon, Polyester, etc., which may be hardly 10% of the cost of pure silk, is rampant. It is very difficult for the consumers to detect the same and these products are passed on as pure silk, thus depriving "the consumers the real value" and "the livelihood of the stakeholders."
India took the lead by launching Silk Mark with twin objectives of Consumer Promotion of silk. Thus the Silk Mark Label, for assurance of pure silk, came into existence and has become the only quality assurance mark for silks across the world. It is advised that whenever you buy silk, ensure it carries the Silk Mark Label as it is the only assurance of purity of silk.
