How to Care for a Cashmere Sweater

Cashmere Care Is Simple Once You Know the Rules

A well-maintained cashmere sweater lasts a decade or more. A neglected one pills, shrinks, or gets eaten by moths within a season. The difference is not time or effort — it is knowing which five or six things actually matter and doing them consistently.

This guide covers the full lifecycle: wearing, washing, drying, depilling, storing, and seasonal maintenance. If you only remember one rule from this entire page, make it this: fold, never hang.

Daily Wear and Rotation

Cashmere fibers need recovery time between wears. The natural elasticity in the fiber allows it to bounce back from the compression and stretching of a full day of wear — but only if you give it at least 24 hours of rest.

Rotate your cashmere. Do not wear the same cashmere sweater two days in a row. If you wear cashmere daily, keep at least two in rotation. This single habit dramatically reduces pilling, stretching, and wear patterns at pressure points like elbows and shoulders.

Air it out after wearing. Lay the sweater flat on a clean surface or drape it over the back of a chair overnight. Cashmere fibers naturally release absorbed odors and moisture when exposed to air circulation. Most of the time, this is all the "cleaning" your sweater needs between washes.

Put jewelry on after the sweater, remove it before. Rings, bracelets, watches, and necklace clasps are the number one cause of snag damage in cashmere. Make it a habit to dress in sequence: base layer, cashmere, then accessories.

Washing: Less Is More

Cashmere does not need washing after every wear. Overwashing is one of the fastest ways to shorten a cashmere sweater's life because every wash cycle — even a gentle hand wash — creates some mechanical stress on the fibers.

Wash every 3 to 5 wears, or when the sweater has visible stains or an odor that overnight airing does not clear. Spot clean small marks between full washes using a damp cloth with a drop of cashmere detergent.

Hand Wash Method (Recommended)

1. Fill a clean basin with cold water (never above 30°C / 86°F)
2. Add a teaspoon of pH-neutral cashmere or wool detergent
3. Submerge the sweater and soak for 15-30 minutes — no rubbing or wringing
4. Drain, refill with clean cold water, and rinse until no suds remain
5. Press water out between towels — never wring or twist
6. Lay flat on a dry towel and reshape to original dimensions

Machine Wash (When Appropriate)

Front-loading machines with a wool or delicate cycle can safely clean cashmere. Use a mesh laundry bag, cold water, lowest spin, and cashmere detergent. Never use a top-loader with a center agitator.

Drying: The Non-Negotiable Rules

Drying mistakes cause more cashmere damage than washing mistakes. Three rules that are not flexible:

• Never tumble dry. Even "air dry" or "no heat" dryer settings create friction that damages fibers.
• Never hang to dry. Water weight stretches shoulders and distorts the body shape permanently.
• Never use direct heat. Radiators, hairdryers, and direct sunlight all cause fiber damage and potential shrinkage.

Always dry flat on a clean towel. Reshape the sweater while still damp — once dry, the shape is locked in. Flip once during drying for even airflow. Full drying takes 12-24 hours depending on knit weight and humidity.

Dealing With Pilling

Pilling is normal. Every cashmere sweater pills, especially in the first few wears. It is not a sign of low quality — it is loose surface fibers working their way out of the knit. Higher-quality cashmere pills less over time because the fibers are longer and less likely to come loose, but the initial pilling happens to all grades.

How to Remove Pills

Tool	Best For	Risk Level
Cashmere comb	Regular maintenance, gentle removal	Very low — safest option
Sweater stone	Moderate pilling over larger areas	Low — slightly more abrasive than a comb
Electric fabric shaver	Heavy pilling on durable knits	Medium — can cut into the knit if set too close
Lint roller	Surface lint only	None — does not actually remove pills

Use a cashmere comb for regular maintenance. Lay the sweater flat, hold the fabric taut with one hand, and gently sweep the comb in one direction. Do not press hard or saw back and forth. After a few sessions, the sweater will shed its loose fibers and pilling will slow dramatically.

Storage: Seasonal and Day-to-Day

Day-to-Day Storage

• Fold, never hang. Hangers stretch the shoulders and create permanent bumps in the knit. Fold cashmere along the natural lines of the garment.
• Give each piece its own space. Stacking too many heavy items on top of cashmere compresses the fibers and creates permanent creases.
• Store in a cool, dry drawer or shelf. Avoid areas with direct sunlight, humidity, or temperature swings.

Seasonal Storage

Before putting cashmere away for the season:

1. Wash everything. Moths are attracted to body oils and food residue, not the fiber itself. A clean sweater is significantly less likely to attract larvae.
2. Dry completely. Any residual moisture can cause mildew during storage.
3. Add moth deterrents. Cedar blocks, lavender sachets, or cedar rings placed with the folded sweaters. Replace or refresh cedar annually (light sanding restores the scent).
4. Use breathable storage. Cotton garment bags, canvas boxes, or breathable zip containers. Avoid sealed plastic — it traps moisture and creates an environment where mildew thrives.
5. Check periodically. Open stored cashmere every 6-8 weeks during the off-season to air it out and check for moth damage.

Stain Removal Quick Reference

Stain Type	Treatment
Coffee / tea / wine	Blot immediately with cold water, then spot clean with cashmere detergent. Do not rub.
Oil / grease	Sprinkle cornstarch or talc on the stain for 20 minutes to absorb oil, then brush off gently.
Ink	Dab with rubbing alcohol on a cotton swab — test an inconspicuous area first.
Makeup / foundation	Blot with a cloth dampened with micellar water, then rinse with cold water.
Deodorant marks	Rub gently with a nylon stocking or damp cloth. Prevention: let deodorant dry before dressing.

Year-Round Care Calendar

When	What to Do
After every wear	Air out overnight, check for stains or snags
Every 3-5 wears	Hand wash or machine wash on wool cycle
Monthly (during heavy use)	Depill with a cashmere comb, inspect for moth damage
End of season	Wash all pieces, dry completely, store with cedar in breathable bags
Every 6-8 weeks (storage)	Open and air out stored cashmere, refresh cedar blocks
Start of season	Air out stored pieces, steam gently to remove creases, inspect condition
