Cashmere socks need gentle hand-washing in cool water with a wool-safe detergent, then flat drying away from heat.
Cashmere socks feel incredible for about three wears — then a careless machine spin can turn a $40 pair into stiff felt. Proper care takes about ten minutes of hands-on time, and the payoff is socks that stay soft through many winters. Whether you just bought your first pair or are rescuing a favorite, the rules below are simple to remember.
How Often Should You Wash Cashmere Socks?
Wash them less than you think. Cashmere fibers self-clean between wears, and over-washing strips natural oils. Airing socks out for 24 hours between wears handles everyday freshness. Wash when soiled or after heavy activity — for most people, every three to five wears during winter. Rotate pairs so each gets a full rest day; this extends knit life more than any fancy detergent.
Hand-Washing: The Right Way
Hand-washing is the safest method and isn’t fussy. Fill a basin with cool or lukewarm water — never hot, which causes felting. Add a small amount of wool or delicates detergent; standard soap is too harsh. Swirl gently, soak for about five minutes. Do not rub, scrub, or wring. Drain and refill with fresh cool water to rinse, repeating until clear. Keep water temperature consistent between wash and rinse — sudden warmth shocks fibers and encourages shrinkage. To remove excess water, lay a clean towel flat, place socks on top, roll up, and press gently. Never twist or wring wet cashmere; fibers are weakest when saturated.
Drying and Storing So They Keep Their Shape
Reshape each sock to natural length and width, then lay flat on a dry towel away from direct sunlight, radiators, and heaters. High heat dries out fibers and can cause shrinking even after a perfect wash. Flip once halfway through drying; depending on humidity, this takes a few hours to overnight. Speed is not the goal.
Store cashmere socks folded flat in a drawer — hanging stretches the knit and leaves ridges. A cool, dry, breathable space prevents moisture-trapping that invites moths. For long-term storage, add cedar blocks or lavender sachets to repel moths naturally. Pilling is normal; use a cashmere comb or fabric shaver to remove bobbles — pulling by hand can snag the yarn.
| Care Step | Do This | Avoid This |
|---|---|---|
| Washing | Hand-wash in cool water with a wool-safe detergent | Machine cycles, hot water, harsh soaps |
| Drying | Press in a towel, reshape, lay flat to air-dry | Tumble drying, wringing, hanging wet |
| Storing | Fold flat in a cool, dry, breathable drawer | Hanging, airtight plastic, damp spaces |
| Maintenance | Comb away pilling with a cashmere tool | Pulling bobbles by hand, over-washing |
| Cleaning caution | Follow the care label on each pair | Dry cleaning, which strips natural oils |
Fixing Common Mistakes
If a pair has been through the machine, damage isn’t always permanent. Pantherella notes that even a delicate cycle can cause felting and shrinkage, so check whether fibers have bonded. Light shrinkage can be coaxed back by soaking in lukewarm water with a little hair conditioner, gently stretching back to shape while wet, and laying flat to dry. Heavy felting — stiff, dense fabric — cannot be reversed; repurpose the socks as loungewear or dusting cloths. If your care label says machine wash, follow it; some tighter knits tolerate a gentle cycle with a mesh bag, but this conflicts with stricter hand-wash-only guidance from other brands. When in doubt, hand-washing is safer.

Bottom line: treat cashmere socks as a delicate investment — hand-wash in cool water, dry flat, and store folded. The Telegraph’s care guidance and The White Company’s product guide agree: gentle washing, flat drying, patience over shortcuts.
FAQs
Can you put cashmere socks in the dryer?
No. Tumble drying is the fastest way to ruin them — heat and tumbling cause felting, shrinking, and loss of softness. Press out water with a towel and lay flat to air-dry.
Why do my cashmere socks pill so fast?
Pilling happens when short fibers work loose from friction inside shoes; it’s natural, not a defect. Remove bobbles with a cashmere comb or fabric shaver — pulling by hand risks snagging.
Is it okay to machine wash cashmere socks if I use a mesh bag?
Some brands allow a delicate cycle with a mesh bag, but others recommend hand-washing only. Machine agitation stresses wet fibers. For safest results, hand-wash in cool water; check your care label first.
