In short

  • Wash at cold, 30°C (86°F) maximum on a hand wash, or delicates in a mesh bag cycle, using pH-neutral, no enzymes, no bleach.
  • Dry flat or on a padded hanger, never in sun. Iron: cool, inside out, slightly damp.
  • Silk is dimensionally stable, so the main risks are heat damage and finish rather than shrinkage.

Silk is a protein fibre like wool, so biological detergents dissolve it too. This is the single most common way silk garments are ruined.

Care guidance by garment

Use a hand wash, or delicates in a mesh bag cycle and pH-neutral, no enzymes, no bleach. Sunlight degrades silk faster than almost any other fabric — it yellows and weakens. Dry it in shade and store it in the dark.

Drying and ironing

Dry flat or on a padded hanger, never in sun. For ironing: cool, inside out, slightly damp.

Deodorant and perspiration are more damaging to silk than dirt. The aluminium salts in antiperspirant permanently stain and weaken the fibre.

How long it should last

Five to twenty years, almost entirely determined by sun and sweat exposure.
