Silk and cashmere are both durable natural fibres when cared for correctly — and both are surprisingly easy to damage with the wrong approach. The mistakes that ruin luxury scarves are almost always the same: hot water, machine washing, wringing, and incorrect drying. This guide covers the correct care protocol for each material, so your investment lasts decades rather than a season or two.
Why Silk and Cashmere Need Specialist Care
Silk and cashmere are protein fibres — they are made from animal-derived proteins rather than plant cellulose (like cotton and linen) or synthetic polymers. Protein fibres are uniquely sensitive to heat and harsh detergents because the same chemical processes that break down the fibre structure also break down proteins in other contexts — this is why hot water, alkaline detergents, and mechanical agitation are all damaging.
Heat above approximately 30°C causes protein fibres to shrink, felt, and stiffen irreversibly. Alkaline detergents (most standard laundry detergents are alkaline) strip the natural oils from the fibres, causing them to become brittle and lose their characteristic softness. Mechanical agitation (machine washing or vigorous hand rubbing) causes the fibres to mat together — particularly in cashmere, where the tiny scales on each fibre lock together when agitated, causing felting that cannot be reversed.
Understanding these vulnerabilities makes the care rules intuitive: cool water, gentle pH-neutral or specialist detergents, minimal agitation, careful drying.
Caring for Silk Scarves
Washing Silk
The safest approach for printed silk is dry cleaning — particularly for scarves with multiple colours or complex prints, where dye bleed is a risk. A professional dry cleaner who handles silk regularly will know the appropriate solvents and handling. For unpatterned or simple-design silk, hand washing is appropriate and preferable to dry cleaning in terms of preserving the fibre’s natural lustre over time.
Hand washing process:
- Fill a basin with cool water — no warmer than lukewarm. Cold water is preferable.
- Add a small amount of dedicated silk wash (Woolite Delicates, Perk Silk Wash, or similar pH-neutral product). Do not use standard laundry detergent — the alkalinity damages silk fibres.
- Submerge the scarf and gently agitate with your hands for 1–2 minutes. Do not rub or scrub the fabric against itself.
- Drain and refill with clean cool water. Gently squeeze (do not wring) to rinse. Repeat until the water runs clear with no soap.
- Press excess water out gently. Never twist or wring.
Drying Silk
Lay the scarf flat on a clean dry towel. Roll the towel and scarf together and gently press to absorb excess moisture — do not wring. Unroll and transfer the scarf to a clean dry surface or over a padded hanger to finish drying.
Keep silk out of direct sunlight while drying — UV exposure fades silk dyes, particularly in warm colours. Do not use a tumble dryer. Do not hang a heavy wet silk scarf directly from one point, as the weight of the water can distort the weave.
Ironing Silk
Iron silk on the reverse side while still slightly damp, using the silk setting on your iron (the lowest heat). A pressing cloth between the iron and the scarf adds an extra layer of protection. Never iron a completely dry silk scarf on the right side — the heat and direct contact can create a glazed finish that is difficult to reverse.
Storing Silk
Store silk scarves folded in breathable fabric bags or wrapped in acid-free tissue paper. Avoid plastic bags, which can trap moisture and cause mould. Keep away from direct sunlight, as even ambient UV exposure fades dyes over time in storage.
The most damaging risk for stored silk is perfume and hairspray residue, which can cause permanent staining over time. Always store scarves after wearing, not while still scented.
Caring for Cashmere Scarves
Washing Cashmere
Cashmere can be hand washed more readily than silk, though the same principles of cool water and gentle detergent apply. Many cashmere producers recommend hand washing over dry cleaning because the dry cleaning solvents can gradually affect the cashmere’s natural lanolin oils and characteristic softness.
Hand washing process:
- Fill a basin with cool water — cold is preferable to lukewarm. Never hot.
- Add a small amount of cashmere-specific wash (Eucalan, Woolite, or baby shampoo — all work well as the mild pH is appropriate for protein fibres).
- Submerge the scarf and gently squeeze it through the water. Do not rub, agitate, or scrub. The goal is to move the water through the fibre, not to create mechanical friction.
- Drain and refill with clean cool water. Gently squeeze again to rinse. Repeat until water runs completely clear.
- Gently press out excess water — do not wring or twist.
Drying Cashmere
This step is critical and is where most cashmere damage occurs. Cashmere stretches significantly when wet — the weight of the water in the fibres causes the fabric to elongate if it is hung while wet. A cashmere scarf hung to dry will be visibly distorted in shape by the time it is dry.
Lay the scarf flat on a clean dry towel in its natural shape. Reshape it gently while wet — this is when you can correct any distortion. Allow to dry completely at room temperature, away from heat sources and direct sunlight. Do not tumble dry under any circumstances — the heat and mechanical agitation will cause irreversible felting and shrinkage.
Dealing with Pilling
Pilling is a natural characteristic of cashmere, particularly in the first few washes as loose surface fibres shed. Pilling is not a sign of low quality — all cashmere pills to some degree initially. However, the extent and persistence of pilling is a quality indicator: Grade A long-staple cashmere pills lightly in the first season and then stabilises significantly; short-fibre budget cashmere pills continuously and progressively.
Remove pills with a cashmere comb (a purpose-made tool with fine metal teeth that catches pills without damaging the underlying fabric) or a fabric shaver set to a low speed. Never pull pills off by hand — this pulls surrounding fibres and creates a hole or thin patch.
Storing Cashmere
Always wash cashmere before storing for the season — body oils and food residue attract moths. Store folded (not hung — hanging cashmere over time causes it to stretch at the hanging point) in a breathable fabric bag with a cedar block or lavender sachet. Cedar naturally deters moths; lavender is a traditional alternative. Replace cedar blocks annually as the deterrent effect diminishes.
Never store cashmere in sealed plastic bags. The lack of airflow traps moisture and can cause mildew growth, particularly in humid climates.
Products Worth Having
A small toolkit significantly extends the life of luxury scarves:
- Cashmere comb: Essential for removing pills without damaging the fabric. A basic cashmere comb costs $10–20 and extends the wearable life of a cashmere scarf by years.
- Silk wash or baby shampoo: A dedicated gentle wash appropriate for protein fibres. Eucalan Wool Wash (no-rinse formula) is particularly convenient for cashmere — no rinsing required.
- Pressing cloth: A clean cotton cloth between your iron and the scarf prevents direct heat contact on silk.
- Cedar blocks: Place in wardrobe and storage bags as a moth deterrent. Replace annually.
- Breathable fabric bags: Muslin or cotton bags allow airflow while keeping dust off stored scarves.

Frequently Asked Questions
Can I machine wash my cashmere scarf?
Not safely on most machines. Some modern machines have a dedicated wool/cashmere cycle with very gentle agitation and cold water, and some cashmere producers now test their products for machine washability. However, the standard recommendation remains hand washing because even gentle machine cycles involve more agitation than hand washing and risk felting. If you do machine wash cashmere, use the gentlest cycle available, cold water only, in a mesh laundry bag, and accept that you are taking a risk.
How often should I wash a silk scarf?
Silk scarves do not need to be washed as frequently as clothing. Washing too often actually reduces the lifespan — each wash cycle, however gentle, produces some wear. Wash when visibly soiled or after contact with perfume or body products. For a scarf worn occasionally as an accessory, washing two to three times per season is typical. Air the scarf after wearing by laying it flat for an hour before storing.
How do I get a stain out of a silk scarf?
Act quickly — silk is particularly vulnerable to set stains. Blot (do not rub) the stain with a clean damp cloth immediately. Do not use hot water. For oil-based stains, a tiny amount of dish soap worked in gently can help before rinsing. For wine or coloured liquid, blot and then hand wash the whole scarf immediately to prevent an uneven stain boundary. For difficult stains, take the scarf to a professional silk cleaner rather than attempting aggressive home treatment.
How do I remove moths from cashmere?
If you find moth damage, immediately isolate the affected garments to prevent spread. Freeze the affected items for 72 hours in a sealed plastic bag — the cold kills moth larvae. Then wash the cashmere as above to remove any remaining residue. Inspect all stored cashmere carefully and wash everything before returning to storage with fresh cedar blocks.
