How to wash cashmere?

Proper care of your cashmere garments ensures their luxurious softness and elegance endure season after season. At Yves Salomon, we recommend gentle hand washing with cool water and specialized detergents that preserve the natural oils within these precious fibers. Our comprehensive guide covers hand-washing techniques, machine-wash options for modern care, proper drying methods, and seasonal storage solutions—all designed to maintain the exceptional quality and refined texture that makes cashmere so coveted.

Why Cashmere Needs Special Care

Cashmere is an extraordinary natural treasure harvested from the undercoat of cashmere goats. These remarkable fibers measure just 11-18 microns in diameter—finer than human hair and approximately ten times finer than regular wool. This exceptional delicacy creates cashmere's signature softness and warmth, but also explains why these precious fibers require attentive care.

Each fiber contains natural oils that contribute to its distinctive softness and insulating qualities. When you invest in cashmere items, you're acquiring garments made from one of nature's most limited resources—each goat produces only 200-300 grams of this precious down annually during spring molting season.

This inherent rarity makes each piece a true investment. With proper care, your cashmere can maintain its luxurious character for up to 30 years, becoming cherished heirlooms that retain their elegance across decades. The French luxury heritage behind cashmere craftsmanship elevates these fibers beyond mere fabric to art—each garment representing generations of expertise in transforming delicate natural materials into enduring symbols of refined comfort.

Essential Tools & Products for Washing Cashmere

Choosing the right cashmere shampoo or detergent

The foundation of proper care begins with selecting a premium washing solution designed specifically for this precious natural fiber. At Yves Salomon, we recommend investing in a dedicated cleanser that respects the delicate nature of these luxurious garments. Look for formulations free from harsh chemicals, dyes, and artificial brighteners that could compromise fiber integrity.

The finest products feature natural ingredients with subtle, sophisticated fragrances—notes of bergamot, cedar, or sandalwood complement the inherent softness of cashmere without overwhelming it. When caring for our cashmere coats, choose solutions optimized for cold water washing that preserve the natural oils within the fibers, maintaining that signature softness and luxurious hand-feel that defines true quality.

Optional accessories for best results

Beyond the essential washing solution, several specialized tools can elevate your care routine to ensure your investment pieces remain impeccable for years. A professional-grade cashmere brush gently removes surface debris and revitalizes appearance between washings. Breathable cotton bags protect against dust while allowing natural fibers to breathe properly—crucial for maintaining integrity.

How to Hand-Wash a Cashmere Sweater: Step-by-Step

Proper hand-washing extends the life of your cashmere sweater, preserving its luxurious softness and elegant appearance. Follow this meticulous process to maintain your investment pieces in pristine condition.

1) Prep & Measure

Begin by checking your sweater for any specific washing instructions on the care label. Then:

  • Fill a clean basin or sink with cold water (68°F/20°C maximum)—never hot, as this can damage fibers
  • Add a small amount of appropriate cleanser:Specialty wool/cashmere detergent (preferred)Gentle baby shampoo (excellent alternative)Mild pH-neutral soap
  • Use less detergent than you think necessary—approximately 1 teaspoon per sweater
  • Turn your sweater inside-out to protect the exterior surface

2) Gentle Wash

The hand-wash process requires patience and a delicate touch:

  • Submerge your sweater completely in the prepared solution
  • Gently press the water through the fibers—never twist, wring or scrub
  • Allow the garment to soak for 10-15 minutes to release dirt and oils
  • For spot stains, apply a small amount of detergent directly with a cotton swab
  • Remember that cashmere is essentially hair—treat it with the same care

3) Rinse Thoroughly

Proper rinsing prevents detergent residue which can affect the feel of your sweater:

  • Drain the soapy water completely
  • Refill basin with fresh cold water of the same temperature
  • Gently press water through the sweater to rinse
  • Repeat this process 2-3 times until water runs clear
  • Avoid sudden temperature changes which can shock and damage the fibers

4) Press and Remove Excess Water

The drying process is critical for maintaining your sweater's original shape:

  • Never wring or twist your cashmere to remove excess water
  • Place the wet sweater on a clean white bath towel
  • Gently roll the towel with the sweater inside, pressing lightly to absorb moisture
  • Unroll and transfer to a flat mesh drying rack or another clean, dry towel
  • Reshape the sweater to its original dimensions while damp
  • Allow to air dry completely away from direct sunlight or heat sources
  • Once dry, steam lightly if needed to restore softness and remove any wrinkles

With proper hand-washing, your cashmere will maintain its luxurious feel and elegant appearance for years to come, making each piece a lasting investment in your wardrobe.

Machine-Washing Cashmere: Can You Trust the Washer?

While hand washing remains the gold standard for cashmere care, modern washing machines offer a convenient alternative when handled properly. The key is understanding how to preserve the luxurious qualities of your garments while using the machine's gentle capabilities.

Check the care label first

Before placing any cashmere item in your washing machine, always examine the care label. Many premium pieces from Yves Salomon include specific care instructions tailored to the garment's particular blend and construction. If the label indicates "hand wash only," follow this guidance. However, many contemporary cashmere garments can withstand machine washing when proper precautions are taken. Higher quality pieces with tightly knit construction generally tolerate machine washing better than loosely woven items.

Select the delicate cycle & cold water

When machine washing cashmere, the proper settings are essential to maintain the integrity of the delicate fibers. Prepare your garments by turning them inside out and placing them in a protective mesh laundry bag to minimize friction. Your machine settings should include:

  1. Cold water temperature (never warm or hot)
  2. Delicate or gentle cycle setting
  3. Shortest possible cycle duration
  4. Low spin speed (maximum 700rpm)

Use a mild detergent specifically formulated for wool and cashmere, or opt for baby shampoo as a gentle alternative. Avoid regular laundry detergents, which contain enzymes that can damage natural fibers.

Post-wash handling

The care you provide after the wash cycle is just as important as the machine settings. Once the cycle completes, immediately remove your garments from the washer to prevent wrinkles and stretching. Never wring or twist the wet cashmere—this damages the delicate fibers and distorts the garment's shape.

Instead, gently press between clean towels to remove excess water, then lay flat on a fresh, dry towel away from direct sunlight or heat sources. While still damp, carefully reshape the garment to its original dimensions, paying special attention to sleeves and hemlines. Allow your cashmere to air dry completely before folding and storing.

Stain Removal & Spot Treatment on Cashmere

When an accidental spill occurs on your precious cashmere, swift action is essential. For immediate spot treatment, dampen a cotton swab with cool water and a small amount of mild detergent. Gently dab—never rub—the affected area, working from the outside toward the center to prevent spreading. For structured pieces or those with linings, spot treating is preferable to full washing.

Different stains require specific approaches:

  • Oil or grease: Apply diluted dish soap to the spot, let sit for 15 minutes, then rinse thoroughly with cool water
  • Wine or colored liquids: Blot immediately with a clean cloth, then treat with specialized cashmere cleanser
  • Makeup: Use a cotton swab with mild detergent, working gently in small circular motions

Always test any treatment on an inconspicuous area first. For particularly stubborn stains, consult a professional cleaner familiar with luxury textiles. After spot treating, press—never wring—excess moisture between clean towels and allow to air dry away from direct heat.

Drying and Reshaping: Keep the Original Shape

Proper drying is essential to maintain the luxurious quality and original silhouette of your cashmere garments. After washing, never wring or twist the fabric—instead, gently press your cashmere between clean towels to remove excess water. Air drying is the only suitable method for these delicate pieces; never use a tumble dryer as it can cause irreversible damage to the fine fibers.

Lay your cashmere flat on a clean, dry towel or mesh drying rack away from direct heat sources. This flat positioning is crucial to prevent stretching or distortion. While the garment is still damp, carefully reshape it with your hands, gently smoothing sleeves, aligning seams, and restoring the relaxed fit. Pay special attention to collars, cuffs, and hems to ensure they dry in their intended form.

Take particular caution to keep cashmere away from radiators, heating vents, and sunlight during the drying process. These heat sources can cause uneven drying, fiber damage, and potential shrinkage or stretching that compromises both the appearance and feel of your cherished pieces.

Between Washes: Daily Cashmere Care & Storage

De-pilling and brushing for longevity

Maintaining your cashmere between washes is essential for preserving its luxurious quality and extending its lifespan. A dedicated cashmere brush is your most valuable tool for daily care. Select one with natural bristles—horsehair brushes are ideal as their supple, fine texture works perfectly with delicate fibers without causing damage.

Establish a methodical brushing routine: lay your garment flat on a clean surface, then gently brush in one direction to lift dust, remove surface lint, and release the natural oils that enhance the appearance of the yarns. This simple practice refreshes your cashmere between wears and helps maintain its natural luster.

For de-pilling, use a specialized cashmere comb or fine sweater comb to gently lift and remove pills that form from normal wear. Work in small sections with a light touch, focusing on affected areas to prevent accumulation that can make even the finest cashmere appear worn.

Fold, store, and travel with cashmere

Never hang your cashmere garments, as this stretches the fibers and distorts the shape. Instead, fold them carefully with acid-free tissue paper between layers to prevent creasing and pressure damage. Store in breathable cotton canvas bags that allow you to identify items without opening.

Your storage location should be cool, dry, and away from direct sunlight and heat sources. For seasonal storage, ensure garments are impeccably clean before putting them away—invisible stains from body oils can attract moths and weaken fibers over time. Consider natural moth deterrents like cedar blocks or lavender sachets, which need refreshing each season.

For extensive collections, professional seasonal storage services offer climate-controlled environments with moth protection—an excellent investment for preserving your most treasured pieces. At Yves Salomon, we offer specialized storage services for your luxury garments during warmer months.

When traveling, fold cashmere items carefully and place them in breathable bags to protect from friction with other luggage items, ensuring your luxurious garments remain in beautiful condition wherever you go.
