How to Wash Silk at Home Without Ruining It
Silk Is More Resilient Than You Think — If You Know the Rules
Silk has a reputation for being impossibly delicate. The reality? Mulberry silk is a protein fibre that, when treated correctly, can last decades without losing its lustre, softness, or temperature-regulating magic. The problems happen when people ignore a few simple rules — the wrong detergent, too much heat, or an impatient tumble dryer.
This guide covers everything: hand washing, machine washing (yes, it's possible), drying, and what to absolutely avoid.
Before You Wash: Check the Label
All silk is not created equal. Standard woven silk and charmeuse silk require hand washing or a delicate machine cycle.
Key terms to look for on care labels:
- Dry clean only — follow this if printed.
- Hand wash — cold water, gentle agitation.
- Machine wash delicate / 30°C — mesh bag, cold or 30°C, silk setting.
Method 1: Hand Washing Silk (Recommended)
Hand washing is the gold standard for silk pillowcases, sleep masks, and scarves. It gives you full control and zero mechanical friction on the fibres.
What You'll Need
- A clean basin or sink
- Cool or lukewarm water (max 30°C / 86°F)
- A pH-neutral, silk-safe detergent (more on this below)
- A clean white towel
Step-by-Step
- Fill the basin with cool water. Add a small amount of silk-safe detergent — about a teaspoon.
- Submerge the silk and gently swirl for 2–3 minutes. Do not scrub, wring, or twist.
- Rinse thoroughly with cool running water until all soap is removed. Soap residue dulls the fabric.
- Do not wring. Gently press the fabric against the basin to remove excess water.
- Lay flat on a clean towel, roll the towel up with the silk inside, and press gently to absorb moisture.
- Reshape and air dry away from direct sunlight and heat.
Method 2: Machine Washing Silk
If your silk item is machine-washable (or you're washing a more robust piece like a silk pillowcase), a machine wash is possible — with care.
The Rules
- Always use a mesh laundry bag. This protects the silk from friction against other garments and the drum.
- Select the delicate or silk cycle on your machine.
- Use cold water or 30°C maximum.
- Wash silk separately or only with other delicates.
- No spin cycle, or use the lowest RPM available.
Detergents: What to Use and What to Avoid
This is where most people go wrong. Silk is a protein fibre (like your hair). Harsh chemicals strip its natural sericin coating — the protein layer responsible for silk's signature softness and sheen.
Safe Detergents
- pH-neutral silk wash (Woolite Delicates, The Laundress Delicate Wash, Puracy)
- A tiny drop of gentle baby shampoo in a pinch
Never Use
- Biological or enzyme-based detergents (they break down protein fibres)
- Bleach or any bleach-containing products
- Regular laundry detergent with brighteners
- Fabric softener (it coats silk and reduces breathability)
- Vinegar in large amounts (a very diluted rinse is sometimes used, but it's risky)
Drying Silk: The Non-Negotiables
Heat is silk's enemy. High temperatures cause silk fibres to contract, stiffen, and lose their lustre permanently.
- Never tumble dry silk — not even on a low setting.
- Never hang in direct sunlight. UV light degrades silk fibres and fades colour.
- Lay flat or hang in shade in a well-ventilated area.
- Silk dries quickly — most pillowcases and silk sleep masks are dry within 1–2 hours at room temperature.
Ironing and Steaming Silk
If your silk comes out with a few creases:
- Iron on the lowest setting (silk setting), always on the reverse side, with a pressing cloth in between.
- A handheld steamer is the safer option — hold it 15–20cm from the fabric and let gravity do the work.
- Never iron silk when wet — it can cause water spots and stretch the fibre.
How Often Should You Wash Silk?
Less frequently than you might think:
- Silk pillowcases: every 1–2 weeks (like a regular pillowcase).
- Silk sleep masks: every 1–2 weeks, or more frequently if you use skincare at night. Browse our Silk Sleep Masks.
- Silk scarves: only when visibly soiled or after heavy wear — spot clean where possible.
The Bottom Line
Washing silk at home is entirely achievable. Cool water, a gentle detergent, no wringing, and air drying in the shade — that's the full formula. Treat it well, and your silk will reward you with years of that cool-to-the-touch, skin-kind luxury.
