Learn how to wash cashmere at home safely with our step-by-step hand-wash guide. Protect ultra-fine fibres and keep your knitwear soft for years.
You spent serious money on a cashmere sweater. Now it needs washing, and you're staring at it wondering if you're about to destroy it.
Here's the truth: you can absolutely wash cashmere at home, and in many cases it's better than dry cleaning. Professional dry cleaning uses chemical solvents that strip natural oils from the fibre over time. Hand-washing with the right technique actually preserves those oils and keeps the cashmere softer for longer.
The key is understanding that not all cashmere behaves the same way in water. A 14.5-micron single-origin fibre like Alxa cashmere has a different structure than a 19-micron blended yarn from a fast-fashion label. Finer fibres need gentler handling — but the process itself is straightforward once you know the steps.
This guide walks you through exactly how to wash cashmere at home, from water temperature to drying technique, so you can stop paying for dry cleaning and start caring for your knitwear properly.
Gather these supplies before you begin:
Do not use regular laundry detergent. Most contain enzymes (protease) designed to break down protein-based stains. Cashmere is a protein fibre. The enzymes that dissolve food stains will also degrade your sweater.
Avoid fabric softener entirely. Cashmere fibres are already naturally soft due to their fine diameter. Softener coats the fibre surface with silicone, which traps odours and reduces the fabric's natural breathability.
This protects the outer surface from friction during washing. Most pilling starts on the face of the garment, so keeping it turned inside out reduces surface agitation.
Use approximately one teaspoon of wool wash per basin of water. Swirl it gently to distribute. The water should feel cool to the touch — if it feels warm on your wrist, it's too hot.
Hot water causes the scales on cashmere fibres to open and interlock. That interlocking is felting, and it's irreversible. Keep the temperature below 30°C and you eliminate this risk entirely.
Place the garment in the water and press it down gently. Do not agitate, scrub, or twist. Just let it soak. The detergent does the work.
If you have a specific stain, press the soapy water through that area with your fingertips. Do not rub the fabric against itself.
Drain the basin and refill with clean, cool water at the same temperature. Press the garment gently to push soapy water out. You may need to rinse twice to remove all detergent. The water should run clear.
A small splash of white vinegar in the final rinse (one tablespoon per basin) helps neutralise any remaining detergent and restores the fibre's natural pH. This is optional but effective.
This is where most people make their mistake. Never wring cashmere. The twisting motion stretches wet fibres and distorts the garment's shape permanently.
Instead, lift the garment out of the water supporting its full weight (don't let it hang and stretch). Lay it flat on a clean towel, roll the towel up with the garment inside, and press firmly. The towel absorbs the excess water. Unroll and repeat with a dry section of towel if needed.
Reshape the garment to its original dimensions and lay it flat on a drying rack or clean towel. Smooth out any wrinkles with your hands.
Keep it away from direct sunlight, radiators, and tumble dryers. Heat damages cashmere fibres and causes shrinkage. Room temperature air-drying is all you need — it typically takes 12 to 24 hours depending on humidity.
Less than you think. Cashmere is naturally odour-resistant because the fibre structure doesn't trap bacteria the way synthetics do.
A good rule: wash after every three to five wears, unless you've spilled something on it. Between washes, air your cashmere out overnight by laying it flat or draping it over a chair. This refreshes the fibre without the stress of washing.
Overwashing cashmere is more damaging than underwashing it. Each wash cycle causes some mechanical stress on the fibres, even with perfect technique. Fewer washes means a longer lifespan.
Some modern washing machines have a dedicated wool or delicates cycle that uses minimal agitation and cold water. If your machine has this setting, you can use it — but only with a mesh laundry bag and a wool-specific detergent.
That said, hand-washing gives you far more control. Machine drums create friction even on gentle cycles, and finer cashmere (under 16 microns) is more susceptible to surface damage from that friction. For a high-quality piece, hand-washing is worth the extra five minutes.
Never use a standard wash cycle. The agitation speed and spin cycle will felt your cashmere beyond repair.

Washing cashmere at home is not risky — it's actually the gentlest option available. Cool water, a pH-neutral detergent, zero wringing, and flat drying. That's it. The entire process takes less than twenty minutes of active work, and your cashmere comes out softer than it would from a dry cleaner. This is one of the reasons we built Vionisxy around ultra-fine Alxa cashmere — when the fibre quality is genuinely high, proper care isn't complicated. It just has to be correct.
