Removing stains from cashmere quickly and carefully helps preserve its delicate fibers and keeps your sweater looking beautiful.
Use cool water, a gentle detergent, and avoid scrubbing to safely lift stains without damaging the fabric.
If the stain persists or the fabric shows signs of damage, take your cashmere to a professional cleaner.

Few wardrobe moments are more stressful than staining your beloved cashmere sweater. Because cashmere is such a soft, delicate fiber, the damage can feel permanent in that moment. Unlike sheep's wool, it doesn't contain lanolin, the natural wax that helps repel moisture. As a result, stains settle into the fabric quickly if you do not treat them properly.

Fortunately, you can remove most stains safely at home with the right products and approach. We spoke with laundry experts Theresa and Corinna Williams, co-CEOs and founders of Celsious, to explain how to treat stains on cashmere. Ahead, we outline the materials you will need, provide a step-by-step guide, and share advice on when it's time to take your sweater to a professional.

How to Respond to a Fresh Stain

Staining your favorite cashmere sweater can surely put a damper on your day. If it happens, act quickly to make the stain removal process easier and prevent further damage.

First, do not panic. Rinse the stained area with cool water as soon as possible. After rinsing, gently blot the area and let it dry. "Resist the urge to scrub, wring, or vigorously rub the stained fabric, as mechanical action can damage delicate cashmere fibers," Theresa warns.

Safe and Unsafe Products for Cashmere

Because cashmere is a very delicate fabric, use products specifically formulated for it. Choose a gentle detergent designed for silk or cashmere for washing and stain removal. If you do not have a delicate detergent on hand, a natural, sulfate- and alcohol-free shampoo without fragrance or dyes can also work, according to Corinna.

Avoid enzyme-based cleaners, as they can break down protein fibers like cashmere over time, which may lead to thinning and holes. Never use chlorine bleach, oxygen bleach (sodium percarbonate), or baking soda on cashmere, Theresa warns.

If you do not have appropriate products at home, take the stained garment to a professional cleaner to help preserve its quality and properly remove the stain.

How to Safely Remove a Stain From Cashmere

Use this step-by-step guide to successfully remove stains from your favorite cashmere items.

Materials

A sink or basin
Cool water
A clean towel
One of the following pre-treaters: Stain spray that's safe for delicates or 1/2 cup of white vinegar for acidic stains to treat coffee, tea, or fruit juice
Delicate detergent or a gentle, natural shampoo

Instructions

Rinse the stained area with cool water.
Pre-treat the stain with a delicates-safe stain spray. For an acidic stain, pour 1/2 cup of white vinegar over the area instead.
Rinse out the pre-treatment with cool water.
Fill a sink or basin with cool water, add a detergent or gentle shampoo, and submerge the garment. Gently massage only the stained area.
Rinse the garment thoroughly, and check whether the stain has lifted.
If the stain remains, repeat the process as needed.
After the final rinse, lay the item flat on a clean towel and allow it to air-dry.

When to Go to a Professional Cleaner

If you spot a stain on your cashmere sweater and start treating it at home, monitor how the fabric responds. If you notice any color loss or thinning fibers in the stained area, stop immediately and take the garment to a professional cleaner, says Corinna. Professionals use specialized spotting agents to treat stains safely while protecting delicate fibers.
