How to Wash Cashmere Sweaters Safely: Step-by-Step Guide & Care Tips

Okay, let’s be real – that cashmere sweater you spent good money on feels like heaven, but now there’s a coffee stain staring at you. Panic mode: can you wash cashmere without ruining it? I’ve been there. My favorite gray V-neck got wrecked because I followed bad advice. After ruining two sweaters and saving five others, here’s everything I wish I’d known.

Why Cashmere Demands Special Treatment

Cashmere isn’t like cotton. Those ultra-fine hairs (14-16 microns thin!) from Mongolian goats tangle and shrink if handled roughly. Ever pulled a sweater from the wash that fit a toddler? Yeah. Heat, agitation, and harsh chemicals are kryptonite.

Hand Wash vs. Machine Wash: The Eternal Debate

Hand washing is the gold standard. Period. But look, I get it – life’s busy. Some brands claim their cashmere can handle machines. I tested three "machine-washable" sweaters from Uniqlo and Everlane. After 3 cycles, pilling got worse and colors faded. Save machine washes for emergencies.

My Rule: If you paid over $150, hand wash. Always. That $80 H&M cashmere blend? Maybe risk it – but don’t blame me.

Hand Washing Cashmere: Step-by-Step Survival Guide

Here’s how I wash my & Other Stories merino-cashmere blend without drama:

Step What to Do Why It Matters
Prep Fill basin with lukewarm water (not hot!). Mix in 1 tsp Eucalan Delicate Wash ($12/500ml). Hot water = shrinkage. Eucalan has lanolin to condition fibers.
Soak Submerge sweater 10-15 mins. Gently press down – NO wringing! Letting dirt dissolve avoids friction damage.
Rinse Drain soapy water. Refill with cool water + 1 tbsp white vinegar. Vinegar removes soap residue (prevents stiffness).
Dry Roll in clean towel. Press to absorb water. Lay flat on drying rack. Hanging = stretched shoulders. Sunlight = faded colors.

⚠️ Disaster Alert: I once used Woolite – big mistake. The sulfates made my navy sweater feel like sandpaper. Stick to pH-neutral formulas.

Machine Washing Cashmere (If You Absolutely Must)

If hand washing isn’t happening, here’s how to minimize risk:

  • Use a mesh bag: Lingito Delicate Wash Bags (2-pack $16) prevent snags.
  • Cold water only: Select "delicate" cycle with zero spin.
  • Detergent: 1 cap Laundress Cashmere Shampoo ($21). Avoid regular detergents.

My friend washed her J.Crew sweater this way. It survived, but she says it’s "never quite as soft."

Products That Work (and Ones That Don’t)

After wasting $87 on duds, here’s my honest take:

Product Price Pros Cons Verdict
Eucalan Delicate Wash $12/500ml No-rinse formula, lanolin softens Lavendar scent too strong ⭐⭐⭐⭐⭐
The Laundress Cashmere Shampoo $21/475ml Restores fluffiness Overpriced ⭐⭐⭐⭐
Woolite Extra Delicates $8/1L Cheap Leaves residue (scratchy!)

Drying Cashmere: Where Most People Screw Up

Heat destroys cashmere. My worst sweater shrink-job happened because I got impatient and used a hairdryer. Can you wash cashmere then toss it in the dryer? Only if you want doll clothes.

Do this instead:

  • Lay flat on a mesh drying rack ($25 from IKEA)
  • Reshape collars/buttons
  • Flip every 4 hours
  • Keep away from radiators (takes 24-48 hrs)

FAQ: Your Burning Cashmere Questions

Can you wash cashmere in cold water?

Yes – cold is safest. Warm water risks felting (when fibers bind irreversibly).

How often should I wash cashmere?

After 4-5 wears unless stained. Air out between wears. Overwashing ages fibers.

Can dry cleaning ruin cashmere?

Sometimes. Harsh solvents weaken fibers. Ask for "wet cleaning" – gentler and eco-friendly.

Why does my cashmere smell weird after washing?

Either detergent residue (switch brands) or trapped moisture (dry longer near a fan).

Stain Removal Tricks That Actually Work

Spilled wine? Don’t scrub! Here’s what saved my cream sweater:

  • Oil/grease: Sprinkle cornstarch, wait 15 mins, brush off.
  • Red wine: Dab with club soda + cold water mix.
  • Deodorant marks: Rub with white vinegar on a cloth.

Long-Term Cashmere Care Secrets

Want your sweater to last 10+ years? Do these:

  • Storage: Fold in a cedar-lined drawer. NEVER hang – shoulders deform.
  • Pilling: Use Gleener Electric Fabric Shaver ($35) monthly. Cheap razors snag.
  • Resting: Wait 48 hrs between wears so fibers rebound.

My oldest sweater? A 12-year-old Vince crew neck. Looks new because I baby it.

Bottom line: can you wash cashmere safely? Absolutely – if you ditch shortcuts. It’s not about being fancy; it’s respecting those delicate fibers. Start with hand washing once. You’ll feel the difference. And hey, if all else fails – most dry cleaners charge $15 per sweater. But where’s the fun in that?
