Quick Answer: Yes, you can wash cashmere at home. Hand wash it in cool water with a drop of gentle wool or baby shampoo, never wring it, and lay it flat to dry. Skip the dry cleaner and your sweater stays soft for years.

That “dry clean only” tag on your cashmere? Consider it a polite suggestion, not a legal contract. You bought that sweater to actually wear it, not to babysit it like a museum piece, and every trip to the dry cleaner costs you time and money you don’t need to spend.

Cashmere is basically fancy goat hair — and hair, as it turns out, does great with a gentle hand wash. Do it right and your sweater comes out soft, clean, and very much not shrunk to doll size. Here’s how, without the panic.

Can you actually wash cashmere at home?

Yes, and most cashmere care labels are being overly cautious. Heat and agitation are the two things that ruin cashmere — not water itself. Keep the water cool and your hands gentle, and you’re golden. That’s honestly 90% of the whole thing.

Dry cleaning uses chemical solvents that can actually dull cashmere’s natural softness over time. A careful hand wash at home is often gentler on the fibers than a trip to the cleaners.

What kind of soap should you use?

Stick to a pH-neutral wool wash or baby shampoo — regular laundry detergent is too harsh and strips cashmere’s natural lanolin oils, leaving it dry and scratchy. A capful in a basin of cool water is plenty; cashmere doesn’t need much soap to come clean. If you don’t have a dedicated wool wash on hand, baby shampoo is an easy substitute most people already own.

What temperature water should you use for cashmere?

Always use cool or lukewarm water — think 60–70°F (15–21°C). Hot water is what shrinks and felts wool fibers into a stiff little pancake, and there’s no undoing it once it happens. If you’re ever unsure, err colder.

How do you wash a cashmere sweater step by step?

1. Fill a basin with cool water and a drop of gentle wool or baby shampoo. Never hot.
2. Submerge and gently swish — no wringing, no scrubbing. Let it soak 5–10 minutes.
3. Rinse in fresh cool water until the suds are completely gone.
4. Press out water gently — squeeze, never twist. Twisting stretches the fibers permanently.
5. Roll it in a towel to press out more water, like a little cashmere burrito.

What’s the biggest cashmere-washing mistake?

Hanging it up to dry. This is where sweaters die. Never hang cashmere — gravity pulls on the wet fibers and it stretches into a sad, droopy shape that never fully recovers. Instead, lay it flat on a dry towel, gently pat it back into its original shape, and let it air-dry away from direct heat and sun. Patience here saves the sweater.

5 Mistakes Everyone Makes With Cashmere

1. Using hot water because it “seems cleaner.” It just shrinks the fibers.
2. Wringing instead of pressing. Twisting is the fast track to a misshapen sweater.
3. Hanging it to dry on a hanger, which stretches the shoulders and neckline.
4. Washing too often. Cashmere doesn’t get dirty fast — airing it out often does the job.
5. Skipping the de-pill step. A few passes with a fabric comb keeps it looking new (the fifth mistake is the one that ages a sweater fastest, even more than bad washing).

Bonus: Keep It Nice Between Washes

• Wash less than you think — cashmere doesn’t need it often; airing it out works wonders.
• De-pill gently with a cashmere comb or fabric shaver for that fresh look.
• Store folded, never hung, ideally with cedar to keep moths away.

Mini FAQ

Can you put cashmere in the washing machine?

Only if the care label allows it and you use a wool or delicate cycle with cold water inside a mesh bag. Hand washing is safer and gives you more control, so it’s the better default if you’re not sure how your sweater will react.

How often should you wash cashmere?

Most cashmere only needs washing every 4–6 wears, or sooner if it’s visibly soiled or has picked up odor. Airing it out on a hanger overnight between wears keeps it fresh without extra washing.

Will hand washing shrink cashmere?

Not if you stick to cool water and avoid heat entirely — shrinking happens from hot water and heat drying, not from the wash itself. If your sweater does shrink slightly, a gentle re-soak in cool water with a light stretch back into shape can sometimes help.

Bottom Line

Cool water, gentle hands, flat to dry — that’s the entire secret to washing cashmere at home. Skip the dry cleaner, save the money, and keep your favorite sweater soft for years. Your cashmere is tougher than its tag admits.

TL;DR

• Wash cashmere in cool water (60–70°F) with gentle wool or baby shampoo.
• Soak 5–10 minutes, never scrub or wring — press the water out instead.
• Lay flat to dry, away from heat; never hang a wet cashmere sweater.
• Wash only every 4–6 wears; air it out and store it folded between washes.
