Can I use regular fabric softener on a silk pillowcase?

No — regular fabric softeners leave a chemical residue that weighs down the silk fiber and reduces its natural breathability. Silk's characteristic softness comes from its own structure, not an additive, so no softener is needed or recommended.

Why Silk Needs Different Rules Than Regular Laundry

Silk fiber is a natural protein, sensitive to heat and to the harsh chemical agents that don't affect cotton the same way. Washing at high temperature or with a regular detergent containing enzymes can progressively dissolve the thread's structure, making the fabric dull and brittle well before its time.

The Protocol That Actually Preserves the Fabric

Hand washing in cold water (or a machine's delicate/silk cycle at 30°C max) with a detergent free of enzymes, followed by flat drying in the shade, preserves the thread's structure for years. Systematically avoiding the tumble dryer and direct ironing without a protective cloth remains the most important rule.

      "Poorly cared-for silk loses its sheen in just a few washes — well-cared-for silk lasts years without losing its original texture.
