Wash and Care for Wool and Cashmere Without Ruining Them
Wool and cashmere aren't as fragile as they seem—they just need a different approach than your everyday cotton tees. We'll walk you through hand-washing, drying, and storage so your investment pieces last for years.
5 min read · IrisThe biggest mistake men make with wool and cashmere is treating them like regular laundry. Machine washing, hot water, and harsh detergents are the enemy. But hand-washing at home takes maybe ten minutes and costs nothing beyond a gentle soap you probably already own.
The payoff is real: sweaters that keep their shape, color, and softness instead of becoming felted disasters or pilled messes. Once you've done it twice, it becomes automatic—and you'll wonder why you ever paid for dry cleaning.
Squeeze, don't wring. Think of it like washing your face, not wringing out a dishcloth.
What you'll need.
- 01Sink or basin
- 02Gentle detergent (baby shampoo, wool wash, or delicate soap)
- 03Clean towels (at least two)
- 04White vinegar (optional, for final rinse)
- 05Cedar block or dried lavender sachet
- 06Soft brush (optional, for spot-treating stains)
Prep · 1 minute
Check the label and turn it inside out
Read the fiber content and care instructions—some blends have specific requirements. Turn the sweater inside out to minimize pilling on the visible surface during washing. If there are any stains, spot-treat them first with a tiny drop of soap and cool water on a soft brush.
Cashmere blends with synthetic fibers often tolerate slightly warmer water than 100% cashmere.
Fill and soak · 2 minutes
Use cool water and a gentle soap
Fill your sink with cool water (around 65–70°F). Add one teaspoon of gentle detergent—baby shampoo, wool wash, or a delicate laundry soap all work. Submerge the sweater and let it soak for five to ten minutes. This loosens dirt and oils without requiring agitation.
Avoid regular laundry detergent, which contains enzymes and surfactants too harsh for delicate fibers.
Wash · 2 minutes
Squeeze gently, don't rub or wring
Lift the sweater and gently squeeze the soapy water through the fabric with your hands. Focus on underarms and collar where sweat accumulates. Work slowly from top to bottom. Never rub, twist, or wring—these actions felt the fibers and cause permanent damage.
If the sweater is heavily soiled, drain the sink and repeat with fresh soapy water for a second pass.
Rinse · 2 minutes
Drain and refill with cool water three times
Drain the sink and refill with cool water. Gently squeeze the rinse water through the sweater. Repeat twice more until the water runs clear and you don't see any soap residue. This step is crucial—leftover detergent dulls color and leaves a stiff feel.
The final rinse can include a tiny splash of white vinegar (one tablespoon per sink) to restore softness and neutralize any remaining soap.
Dry · 3 minutes
Lay flat on a clean towel, never hang
Gently press out excess water by rolling the sweater inside a clean towel—don't squeeze or wring. Unroll and lay the sweater flat on a dry towel in a well-ventilated spot away from direct heat or sunlight. Reshape it to its original dimensions while damp. Let it air-dry completely, which typically takes 12–24 hours.
Flip the sweater halfway through drying to ensure even moisture evaporation on both sides.

Fold, don't hang; use cedar or lavender
Once dry, fold the sweater neatly and store it in a drawer or shelf. Hanging stretches wool and cashmere over time. Place a cedar block or sachet of dried lavender in the drawer to deter moths. Avoid plastic bags, which trap moisture; use breathable cotton storage bags if needed.
Refresh sweaters between washes by laying them flat in fresh air for a few hours—this removes odors without requiring a full wash.
How to know it works.
A properly washed wool or cashmere sweater should feel soft and smell fresh, with no visible soap residue or stiffness. The color should remain vibrant, and the fit should match how it felt when new—not stretched, shrunken, or pilled.
Questions at the mirror.
Can I machine-wash wool or cashmere on the delicate cycle?
Technically, some modern wool blends are machine-washable on a gentle cold cycle, but hand-washing gives you more control and is gentler. If you do machine-wash, use a mesh bag, cold water, and a wool-specific detergent—then lay flat to dry.
What if my sweater already has pilling?
Use a fabric comb or sweater stone to gently remove pills after the sweater is dry. Never pull pills off by hand, as this can damage the underlying fibers. For severe pilling, a professional de-pilling service may be worth the cost.
How often should I actually wash wool and cashmere?
Wool and cashmere resist odor better than most fabrics. Wash every three to four wears, or when visibly soiled. Between washes, air them out and spot-treat any stains.
Is dry cleaning necessary?
No. Professional dry cleaning uses harsh chemicals that can degrade fibers over time. Hand-washing at home is gentler and cheaper. Reserve dry cleaning for stubborn stains or delicate embellishments you're unsure about.
