Quick Answer

Hand washing is the safest method for cashmere sweaters, but a gentle machine wash with a mesh bag works for most modern knits if you use cold water and a delicate cycle. Always avoid hot water, wringing, and fabric softener. Both methods work—choose based on your time and the sweater's construction.

When to Hand Wash vs Machine Wash

Hand washing gives you full control over agitation and water temperature, which is ideal for delicate or loosely knitted cashmere. It also reduces the risk of stretching or felting. Machine washing is faster and more convenient, but it requires a few precautions: always use a mesh laundry bag, select a cold-water delicate cycle with low spin, and never mix with heavy items like jeans.

For both methods, use a mild detergent specifically designed for wool or cashmere. Avoid regular laundry detergent, which contains enzymes that can damage animal fibers. If your sweater has embellishments, beads, or a very loose weave, hand washing is the safer choice.

Step-by-Step Hand Wash Method

Fill a clean basin or sink with cool water (around 30°C / 86°F) and add a small amount of cashmere shampoo. Submerge the sweater and gently press the water through the fabric—do not rub or scrub. Let it soak for 10 to 15 minutes, then drain the soapy water and refill with cool, clean water. Rinse by pressing gently until all suds are gone.

To remove excess water, roll the sweater in a clean, dry towel and press firmly. Never wring or twist, as that can distort the shape. Lay the sweater flat on a drying rack, away from direct sunlight or heat sources.

Step-by-Step Machine Wash Method

Turn the cashmere sweater inside out and place it in a mesh laundry bag. This protects the fibers from friction and snagging. Select the delicate or hand-wash cycle on your machine, set water temperature to cold, and choose the lowest spin speed. Add a capful of wool-friendly detergent to the dispenser.

Once the cycle finishes, remove the sweater immediately to prevent creasing and wrinkles. Do not leave it sitting in the machine. Follow the same drying instructions: roll in a towel to remove moisture, then lay flat to dry. Avoid the dryer entirely—heat and tumbling can cause permanent shrinkage and felting.

Cashmere Washing Steps & Common Mistakes

  1. Check the Care Label: Always read the garment's care tag first. Some cashmere blends or structured coats may have specific instructions. Ignoring the label is the most common mistake. If it says dry clean only, do not machine wash.
  2. Treat Stains Before Washing: Gently dab a small amount of mild detergent on the stain and let it sit for 5 minutes before washing. Rubbing vigorously can spread the stain or damage fibers. Avoid bleach or stain removers—they can weaken cashmere.
  3. Dry Flat, Not Hanging: After washing, lay the sweater flat on a drying rack or a clean towel. Hanging wet cashmere stretches the fabric out of shape due to gravity. Never use a clothes dryer or radiator—heat causes shrinkage.
