How to Wash Cashmere Without Shrinking and Ruining Every Sweater You Own

There are several hard life lessons we all have to learn by experience. Removing scratches from your glasses with the wrong tools will probably result in more scratches. Cleaning your shower curtain is more important than you think. Lastly, washing cashmere at home in the washing machine without taking extra precautions is almost guaranteed to end in a ruined sweater, or two.

Cashmere, while being deliciously soft and sophisticated AF, is also a finicky fabric when it comes to getting clean. However, let’s clarify something right off the bat. You do NOT have to professionally dry clean cashmere sweaters, or any piece of cashmere clothing for that matter. You can clean your cashmere belongings at home successfully, you just have to follow a few extra steps.

Why is Cashmere so Hard to Clean?

Cashmere is a delicate yarn made from goats’ fur which gets fluffier and more lustrous when cleaned, much like human hair. However, it’s also very sensitive to water and heat, and can shrink easily if exposed to a drastic temperature fluctuation.

Contrary to popular belief, it’s actually worse for cashmere in the long run to frequently dry clean it, because the harsh chemicals used at the cleaners can shorten its life and affect the quality of the fabric over time. It’s better to hand wash your cashmere at home, if you can.


How to Hand Wash Cashmere

When it comes to safeguarding fabrics and washing clothes in the gentlest way possible, hand washing is the way to go.

What You’ll Need:

  • A sink or bathtub filled with lukewarm water
  • Some type of gentle cashmere shampoo, or hair shampoo
  • A drying rack
  • A cashmere brush
  • Patience

Fill up a bathtub or sink with lukewarm water and add a couple pumps of a cashmere shampoo, gentle no-wash laundry detergent or even baby shampoo to get the water nice and soapy. Let the clothing soak for five minutes or so and then rise with cool water. Here are a few brands of soap we recommend for this step.

The Laundress Wool & Cashmere Shampoo

The Laundress makes a great laundry shampoo designed specifically for cashmere and wool, which both use the same detergents since they’re both hair. This one works on all cashmere, wool and merino blends, and is formulated to replace the tender care of a dry cleaner.

How to Dry Cashmere

After a good soak and rinse, avoid the inclination to wring out your clothing. The fibers of the yarn are wet, and therefore are weaker. A tough wringing out could result in disfigurement or affect the shape, so it’s better to ball up the fabric and squeeze it out that way. Avoid pulling, stretching or lengthening out in this phase.

You can also use a towel roll-up method, where you place the sweater on top of a towel and roll it up lengthwise, squeezing out the water in the process. Above all, avoid wringing out your cashmere if you can.

After handwashing your cashmere, you’ll want to lay it out flat to dry in the shape you’d like it to stay in. Don’t hang it to dry or it’ll stretch and lose its shape. If you’ve got a flat drying rack, you can use that, otherwise lay out a towel and let it dry slowly.

How to Wash Cashmere in the Washing Machine

While hand washing is definitely the preferred method, you can also use the washing machine to cleanse your cashmere fabrics if you’d like. For best results, place the item of clothing in a mesh washing bag for protection and wash it on a delicates cycle with a dye-free detergent. If you’ve got other customizable settings, make sure the water is cold and the spin rate is as low as possible.

The goal is to avoid agitation, as agitation can shrink or manipulate the fabric in ways you don’t want. If the cycle is as gentle and close to hand washing as possible, you should be okay.

Also, avoid leaving the item of clothing in the machine for a long time after the cycle is over. Remove it promptly and lay it flat to dry using the tips above to avoid extraneous creasing.

How to Treat Stains on Cashmere Clothing

The key here is to not rub, dab or scrub too vigorously to get that dab of mustard out of the sweater. This could disrupt the weave of the fabric and/or leave you with an even worse stain. Gently massage in a stain remover before the next wash, and then let the stain lift from the fibers during the next cleansing cycle.

How Often Should You Wash Cashmere? (And How to Take Care of It Between Wears and Washes)

Thankfully, cashmere doesn’t need to be washed as frequently as other materials. Once every 10 wears should be good, and/or at the end of the fall and winter season when it’s probably getting more use.

You can also grab a boar-bristle cashmere brush for lighting removing fuzz, dirt and little stains between washes. Fold your cashmere sweaters, rather than hanging them, so they don’t stretch and lose their shape. Also, if you’re storing it away for the summer season, place it in an airtight container with cedar wood chips to prevent moths from disrupting the fabric.
