Quick answer
Hand wash your silk lingerie in cool water with a gentle, pH-neutral delicates detergent, then air dry flat away from direct heat or sunlight.
Why a specialist delicates detergent matters for silk
Silk is a natural protein fibre that is more delicate than cotton or synthetics. Regular laundry detergents often contain enzymes, bleach, or high alkalinity that can weaken silk threads, cause yellowing, or dull the sheen. A specialist delicates detergent uses a pH-neutral formula that cleans without stripping the fibre's natural structure. The Clothes Doctor Knitwear & Delicates Detergent, for example, is designed to protect natural fibres like silk while preserving softness and reducing wear over time.
What to avoid when washing silk
Never use hot water, bleach, fabric softener, or a washing machine's regular cycle on silk lingerie. Heat can set stains and shrink the fabric, while harsh chemicals break down the protein fibres. Even gentle machine cycles create friction that can snag or stretch delicate lace and seams. Stick to hand washing with cool or lukewarm water (below 30°C) and a mild detergent. Avoid wringing or twisting the wet garment; instead, press out excess water gently.
How to hand wash silk lingerie with delicates detergent
- Fill a basin with cool water: Use water that feels cool to the touch, ideally below 30°C. Add the recommended amount of delicates detergent and swirl to dissolve. Check the detergent label for dosage; too much suds can be hard to rinse out completely.
- Submerge and gently agitate: Place your silk lingerie in the water and gently press it down to saturate. Swish the garment softly with your hands for about 30 seconds. Do not rub, scrub, or twist the fabric. If you see colour bleeding, stop immediately and rinse in fresh cool water; silk can release dye in the first few washes.
- Soak for 3–5 minutes: Let the lingerie sit in the soapy water for no longer than 5 minutes. Prolonged soaking can weaken silk fibres or cause dyes to run. Set a timer — silk should never soak for more than 10 minutes total.
- Rinse thoroughly with cool water: Drain the soapy water and refill the basin with fresh cool water. Gently press the garment to push suds out, then repeat until no bubbles remain. Avoid running water directly onto the fabric. Residual detergent can attract dirt and cause silk to yellow over time.
- Remove excess water without wringing: Lay the wet lingerie on a clean, dry towel. Roll the towel up gently and press to absorb moisture. Unroll and transfer the piece to a second dry towel to air dry. Never hang wet silk lingerie; the weight of the water can stretch the fabric out of shape.
- Dry flat away from heat and sunlight: Place the silk piece on a drying rack or a flat towel in a well-ventilated area out of direct sunlight. Do not use a tumble dryer, radiator, or hairdryer. Direct sunlight can fade silk dyes, and heat can cause shrinkage or brittleness.
