How to wash cashmere without ruining it: the atelier's guide
di—Fondatore SILKinCOM
"Cashmere does not wear out from being worn: it is ruined in ten minutes of the wrong wash. Water, timing, gestures and storage, the way we do it in the atelier."
The first genuinely cold morning always arrives without warning. You open the drawer, pull out the cashmere scarf that has been folded since March and, on your way out, you notice the flattened crease down the front, the closed-in smell of the drawer, perhaps a coffee stain from an evening you had forgotten. At that point the temptation is always the same: put it in the machine and stop thinking about it. That single gesture ruins more cashmere than any winter spent wearing it.
Cashmere does not wear out from being worn. It is ruined in ten minutes of the wrong wash, almost always for three reasons: water that is too hot, too much movement, and drying on a hanger. Here is how we treat it, and how we suggest you do it at home.
How often a cashmere scarf really needs washing
Less often than you think. Cashmere is an animal fibre that breathes and recovers in the open air: after a day outdoors, in most cases it is enough to lay it flat for a few hours in a ventilated room, away from radiators, for it to feel fresh again. Washing after every wear does not make it cleaner, only tired.
A rule of thumb that works: wash it at the end of the season, before putting it away, and during winter only when it is genuinely needed — a stain, or a smell the air has not lifted. For a piece worn at the neck rather than against the skin all day, that usually means two or three washes a season.
Before it touches water: three quick checks
Read the composition
One hundred per cent cashmere and a wool blend behave differently in water. On our , as on every pure-cashmere piece, the instruction is a single one: hand wash. If the label is illegible, or the piece was a gift of uncertain origin, start from our guide to and work out what you are dealing with.
Treat the stain immediately
A fresh stain comes out with lukewarm water and a touch of gentle detergent, blotting from the outside towards the centre with a white cloth. Never rub: on cashmere, friction opens the fibre and leaves a dull halo that survives the wash.
Prepare the water and the detergent
You need a clean basin, lukewarm water — 30 degrees at most, the temperature your hand sits in comfortably — and a detergent made for cashmere or delicates. No ordinary laundry detergent, no bleach, no fabric softener: softener leaves a film that weighs the fibre down and removes exactly the softness you paid for.

Hand washing, step by step
Lay the piece open in the water, press gently with your hands so the water passes through the fibres, and leave it to soak for a few minutes, no more. Cashmere does not need time, it needs gentleness: every twist, every rub, every abrupt movement shortens the life of the piece.
Rinse in water at the same temperature, changing it two or three times until no foam is left. Then comes the most important moment: never wring it. Press the piece between your hands to push the water out, lay it flat on a towel, roll towel and piece together and press on the roll. That way the towel absorbs the water without the fibre being pulled.
Drying is where most damage happens
A wet cashmere piece is heavy. Hanging it means letting that weight pull the knit downwards: it stretches, loses its shape and never recovers it. This is why it always dries flat, on a dry towel, shaped gently by hand before it is left to rest.
Keep it away from radiators, heaters, hairdryers and direct sun: dry heat stiffens the fibre and fades the colour. All it needs is time, in an ordinary room, turned over once when the towel underneath has become damp.
What about the washing machine?
It can be done, but only under certain conditions, and it remains a compromise. You need a wool or delicates programme at no more than 30 degrees, the spin at its lowest setting or off, a specific detergent, and the piece closed inside a mesh bag. The risk is not the temperature itself: it is the mechanical action of the drum, which is precisely what felts cashmere.
For a scarf or a pashmina, washed two or three times a year, ten minutes by hand is the better investment. To be clear: a felted piece does not come back, and felting is the only truly irreversible damage among everything discussed here.
Pilling is not a defect
In the first few weeks a cashmere piece forms small bobbles, above all where it rubs: the collar of a coat, a bag strap, the armrest of a car. It is not a sign of poor quality: it is the normal behaviour of the short fibres at the surface, which work their way out and tangle. After the first months it subsides on its own.
Remove them with a cashmere brush or a dedicated comb, always working in the same direction and without pressing. Avoid razors and improvised blades: they cut the fibre and create thin patches that later become holes.
Iron as little as possible
Cashmere barely needs it: most creases fall out on their own if you hang the piece in the bathroom for a few hours after a hot shower, or pass steam over it at a distance without resting the iron on it. If the iron really is necessary, use the lowest setting, on the reverse, with a cotton cloth in between, and never linger on one spot.
How to store it, and why folded
At the end of the season the piece goes away clean: moths are drawn to traces of skin and food, not to the fibre itself. Store it folded, never hung, in a box or a cotton bag that lets the air through. Plastic feels protective but traps humidity and encourages mould.
Natural moth repellents work well, from cedar to lavender, replaced each year as they lose their strength. All the instructions by fibre are on our product care page, which applies equally to the Bellagio pashmina and to wool scarves.
A piece that lasts twenty years, if treated properly
A pure-cashmere scarf such as the Varenna, at 120 euros, is not a purchase to repeat every season: washed three times a year as it should be, it accompanies fifteen or twenty winters. Seen that way, the arithmetic changes completely — and so does the way you handle it.
It is the same reason it is worth understanding what you are buying before you spend: the difference between a long fibre and a short one, between well-combed cashmere and a mediocre one, shows precisely after the fifth wash. We wrote about it in our guide on how to recognise a real cashmere pashmina.
The questions our clients ask
How often should cashmere be washed?
Two or three times a season for a piece worn at the neck, plus the end-of-winter wash before storing it. Between washes it is enough to air it flat for a few hours, away from radiators.
Is dry cleaning better?
It is not necessary. Our instruction for pure-cashmere pieces is hand washing in lukewarm water, which is gentler than many dry-cleaning cycles and leaves no solvent residue in the fibre.
Can fabric softener be used?
No. Softener deposits a film on the fibres that removes softness and breathability — exactly the opposite of what cashmere needs. A specific detergent, in a small quantity, is all it takes.
How do you remove a coffee or wine stain?
Immediately, blotting with lukewarm water and a very little gentle detergent, from the outside of the stain towards the centre, with a white cloth. Without rubbing and without hot water, which sets organic stains.
The piece has felted: can it be saved?
Sadly not, or only marginally. Felting is the permanent interlocking of the fibres caused by heat and movement: it is why we insist on lukewarm water and slow gestures.
How should it be stored over the summer?
Clean, folded, in a cotton bag in a dry place, with a natural moth repellent replaced each year. Never hung and never sealed in plastic.
The wash is part of the piece
An accessory in a noble fibre does not end when it leaves the shop: it continues in the hands of whoever owns it. Ten minutes of care twice a year separate a scarf that lasts a season from one that accompanies twenty winters and is still, years later, the one you reach for when it is genuinely cold outside.
Anyone who wants to understand the fibres closely before choosing can start with our guide to noble fibres; anyone considering a first cashmere piece will find the whole selection in cashmere and wool scarves and in the pashminas.
