Can You Machine Wash Cashmere? A Complete Care Guide

Cashmere sweaters and garments represent a special luxury in any wardrobe. Their incredible softness and warmth make them treasured pieces, but many cashmere owners find themselves hesitant when it comes to cleaning these delicate items. The question “Can you machine wash cashmere?” is one of the most common concerns, and for good reason. This comprehensive guide will walk you through everything you need to know about properly caring for your cashmere garments to ensure they remain beautiful for years to come.

Understanding Cashmere Before Washing

Cashmere isn’t just any wool—it’s a premium fiber harvested from the soft undercoat of cashmere goats. What makes cashmere special is its exceptional fineness; quality cashmere fibers measure under 16 microns in diameter, significantly thinner than human hair. This delicate structure gives cashmere its signature softness and lightweight warmth but also makes it more vulnerable during washing.

Unlike regular wool, cashmere fibers are:
– Extraordinarily fine and soft
– Highly insulating despite being lightweight
– More prone to damage from rough handling
– Naturally elastic but can lose this quality with improper care

Many people assume all cashmere must be dry cleaned, but this isn’t always the case. Understanding the ultimate guide to cashmere care and washing can help you make better decisions about how to clean your garments. With proper techniques, many cashmere items can be safely cleaned at home, potentially saving you money while extending the lifespan of your luxury garments.

The key to successful cashmere care lies in understanding its unique properties and treating it with appropriate gentleness throughout the cleaning process. This care begins with reading and following the garment’s care label instructions.

Reading Care Labels: Your First Step

Before attempting any cleaning method, always check the care label on your cashmere item. Manufacturers provide these instructions based on the specific construction of the garment, the quality of cashmere used, and any additional materials or embellishments present.

Common care labels for cashmere include:

• “Machine Washable” – The garment can be machine washed following specific instructions (usually cold water, gentle cycle)
• “Hand Wash Only” – Machine washing may damage the item; gentle hand washing is required
• “Dry Clean Only” – The construction or embellishments make water washing risky; professional cleaning is recommended

If your cashmere item’s care label is missing, it’s generally safest to hand wash the item or consult a professional. Understanding cashmere sweater care instructions can provide valuable guidance when labels are unclear.

Some manufacturers may recommend dry cleaning as the safest option, even when gentle machine washing is technically possible. This cautionary approach protects them from liability but may not always be necessary for simple cashmere garments.

Can You Machine Wash Cashmere? The Truth

Yes, many cashmere items can be successfully machine washed, but with specific precautions. The key is understanding when machine washing is appropriate and how to do it correctly to avoid damage.

Several factors determine whether machine washing is suitable for your cashmere:

• Age and condition: Newer, stronger items typically handle machine washing better than older, worn pieces
• Construction: Simpler designs with minimal seams fare better than complex constructions
• Fiber content: Pure cashmere may respond differently than cashmere blends
• Knit density: Tightly knit cashmere is generally more resilient in machine washing

When done properly, machine washing can actually be beneficial for cashmere. It helps preserve the natural lanolin in the fibers, which contributes to cashmere’s softness. However, improper machine washing can cause irreversible damage through felting (when fibers permanently lock together), shrinking, stretching, or distortion.

Learning how to wash cashmere at home properly can save you money on dry cleaning while maintaining your garments’ quality. The gentle agitation of a proper machine wash can even help remove pills and rejuvenate the fabric when done correctly.

When to Choose Hand Washing or Dry Cleaning Instead

While machine washing works for many cashmere items, there are specific situations where alternative cleaning methods are preferable:

• Skip machine washing for:
– Heavily embellished cashmere with beading, sequins, or delicate trims
– Antique or vintage cashmere pieces that may have weakened over time
– Items already showing signs of damage (thinning areas, holes, loose threads)
– Very lightweight or loosely knit cashmere that could easily stretch
– Multi-fabric garments where different materials require different care

Hand washing provides more control over the cleaning process and is generally safer for delicate or special items. The gentle touch allows you to clean without risking the mechanical stress that washing machines can create.

Professional dry cleaning is recommended when:
– The label specifically states “Dry Clean Only”
– The item has complex construction or is lined
– The garment contains multiple fabric types with conflicting care needs
– You’re dealing with difficult stains that require professional treatment

Understanding the differences between hand washing versus dry cleaning cashmere can help you make informed decisions based on your specific garment’s needs and condition.

Machine Washing Cashmere: Step-by-Step Guide

When you’ve determined your cashmere item is suitable for machine washing, follow these detailed steps for best results:

1. Prepare the garment:
   – Check for stains and treat them with a gentle spot cleaner if necessary
   – Turn the garment inside out to protect the outer surface
   – Place in a mesh laundry bag to reduce friction and agitation
   – Wash similar colors together and avoid washing heavy items with delicate cashmere

2. Set up your washing machine:
   – Select the gentlest cycle available (delicate, wool, or hand wash setting)
   – Use cold water only (86°F/30°C or lower)
   – Set the spin cycle to the lowest speed (400-600 rpm maximum)
   – Reduce the cycle duration if your machine allows

3. Choose the right detergent:
   – Use a wool-specific mild detergent without enzymes
   – Look for pH-neutral formulations specifically designed for delicates
   – Baby shampoo can work as a gentle alternative in a pinch
   – Use only a small amount (about half the recommended dose)

4. Avoid at all costs:
   – Fabric softeners (they coat fibers and reduce cashmere’s natural softness)
   – Bleach (even color-safe versions can damage delicate fibers)
   – Enzyme-based detergents (they break down protein fibers like cashmere)
   – Overloading the machine (cashmere needs space to move freely)

For specific garment types, our collection of cashmere sweaters includes detailed care information tailored to different styles and weights.

Remember that front-loading machines generally provide gentler washing action than top-loaders with central agitators, making them preferable for cashmere care when available.

Hand Washing Cashmere: The Traditional Method

Hand washing remains the safest and most controlled method for cleaning cashmere. Follow these steps for optimal results:

1. Prepare your washing basin:
   – Use a clean sink or large basin with no residue from previous products
   – Fill with lukewarm water (85°F/29°C) – neither hot nor cold
   – Add a small amount of wool-specific detergent and mix gently
   – Ensure detergent is fully dissolved before adding garments

2. Wash with care:
   – Fully submerge the cashmere item without bunching or twisting
   – Gently press the water through the fabric using flat hands
   – Avoid rubbing, wringing, or scrubbing motions
   – Soak for 5-10 minutes maximum (longer soaking can weaken fibers)

3. Rinse thoroughly:
   – Drain the soapy water and refill basin with clean, cool water
   – Gently press water through the garment repeatedly
   – Repeat the rinse process 2-3 times until no soap remains
   – Test by squeezing gently – no bubbles should appear

Hand washing offers significant advantages for cashmere care, including complete control over agitation, the ability to focus on specific areas, and minimized risk of stretching or misshaping.

Drying Cashmere Without Damage

Proper drying is just as important as washing when it comes to preserving your cashmere’s shape and feel:

1. Remove excess water safely:
   – Never wring or twist cashmere when wet
   – Gently press water out using flat hands
   – Lay the garment on a clean white towel
   – Roll the towel with the garment inside, applying gentle pressure
   – Unroll and repeat with a dry towel if the item is still very wet

2. Set up for flat drying:
   – Choose a flat, moisture-resistant surface away from direct heat
   – Lay a clean, dry towel over the surface
   – Place the damp cashmere flat on the towel
   – Gently reshape the garment to its original dimensions
   – Pay special attention to sleeves, collars, and hemlines

3. Complete the drying process:
   – Allow 24-48 hours for complete drying
   – Flip the garment halfway through drying
   – Replace the towel underneath if it becomes damp
   – Ensure good air circulation in the drying area
   – Check for complete dryness before storing

Never attempt to speed up drying using radiators, hair dryers, or clothes dryers, as direct heat can cause irreversible shrinkage and fiber damage. Similarly, avoid hanging wet cashmere, as the weight of the water will cause the garment to stretch.

Dealing with Common Cashmere Issues After Washing

Even with careful washing, you might encounter some common issues with cashmere garments:

Addressing Shrinkage:
If your cashmere has slightly shrunk, try gently stretching it when damp. Lay it flat, and carefully pull the fabric to its original dimensions. Hold each section for several seconds before moving to another area. For significant shrinkage, professional restoration may be required, though severe cases may be irreversible.

Managing Pilling:
Pilling (those small balls of fiber on the surface) is natural with cashmere and doesn’t necessarily indicate poor quality. After washing:
– Allow the garment to dry completely before addressing pills
– Use a specialized cashmere comb or pill remover tool
– Work in one direction with gentle, light strokes
– Never use scissors or razors, which can damage the base fabric

Color Issues:
To prevent color bleeding, always wash similar colors together. If fading occurs, specialized wool dye products can refresh the color, but follow package instructions carefully. For general dulling, a rinse with a tablespoon of white vinegar in cold water can help restore brightness.

Shape Distortion:
If your cashmere loses its shape, try rewetting it completely, gently reshaping, and drying flat again. For severe cases, steam from an iron held several inches away (never touching the fabric) can help relax fibers before reshaping.

Understanding cashmere cleaning tips to avoid shrinkage can help prevent these issues before they occur, saving you time and preserving your garment’s appearance.

Storing Clean Cashmere Properly

Proper storage is essential for maintaining cashmere between wearings and seasons:

• Folding vs. Hanging:
• Always fold cashmere rather than hanging
• Place tissue paper at fold points to prevent creasing
• Stack heavier items at the bottom, lighter ones on top

• Allow space between stacks for air circulation

• Ideal Storage Environment:

• Cool, dry location away from direct sunlight
• Temperature between 60-75°F (15-24°C)
• Moderate humidity (40-60%)

• Good air circulation to prevent mustiness

• Protection Methods:

• Use breathable cotton storage bags (never plastic)
• Place cedar blocks or lavender sachets nearby (not directly on garments)
• Keep stored cashmere elevated from floor level

• Insert acid-free tissue paper in sleeves to maintain shape

• Seasonal Storage:

• Always clean thoroughly before long-term storage
• Inspect for damage or moth evidence before storing
• Air out stored items briefly every few months
• Re-fold occasionally to prevent permanent creases

Our collection of women’s cashmere cardigans includes pieces designed with long-term wearability in mind, making proper storage especially worthwhile.

Extending Cashmere Lifespan: Preventative Care Tips

The best way to maintain cashmere is through regular preventative care between washings:

Smart Wearing Practices:
Rotate your cashmere garments to avoid wearing the same piece multiple days in a row. This gives fibers time to recover their natural elasticity. Consider wearing a light layer underneath to reduce direct contact with skin oils and perfumes, which can degrade fibers over time.

Spot Cleaning Techniques:
Address spills immediately by blotting (never rubbing) with a clean, white cloth. For small stains, use a solution of lukewarm water and a drop of wool detergent applied with a clean cloth, then blot dry. Always test any cleaning solution on an inconspicuous area first.

Refreshing Between Washes:
Most cashmere doesn’t need washing after every wear. Instead:
– Hang the garment in a steamy bathroom to release wrinkles and odors
– Air out on a hanger away from direct sunlight for several hours
– Use a fabric refresher spray designed for wool (test in an inconspicuous area first)

Optimal Washing Schedule:
Most cashmere items need washing only after 3-5 wears, unless visibly soiled or odorous. Excessive washing can accelerate wear, so judge by condition rather than a fixed schedule.

Our men’s cashmere cardigans are crafted to maintain their appearance with minimal care when these preventative practices are followed.

Professional Cashmere Care: When to Seek Expert Help

While home care is suitable for most cashmere, some situations call for professional expertise:

When to Choose Professional Cleaning:
– Stubborn or oily stains that resist gentle spot treatment
– Very expensive or heirloom cashmere pieces
– Items with linings, complex construction, or multiple materials
– Garments with significant embellishments or decorative elements
– After several home cleanings to remove deeper soil buildup

Finding a Qualified Cashmere Specialist:
– Ask if they hand clean delicate woolens separately
– Confirm they use appropriate cleaning solutions for cashmere
– Inquire about their process for blocking (reshaping) after cleaning
– Check if they have experience with luxury knitwear
– Request references or read reviews from other cashmere owners

Cost Considerations:
Professional dry cleaning for cashmere typically costs $8-25 per item, depending on complexity and location. While more expensive than home care, professional cleaning can be worth the investment for special pieces or complex stains. Most quality cashmere needs professional cleaning only once or twice per season with proper home care between cleanings.

For particularly valuable pieces like our cashmere turtlenecks, occasional professional cleaning can complement your regular home care routine.

Common Misconceptions About Cashmere Care

Several myths persist about cashmere care that can lead to unnecessary expense or improper handling:

MYTH: “Cashmere can never be machine washed.”
FACT: Many cashmere garments can be successfully machine washed using appropriate settings and techniques. Always check the care label, but don’t assume dry cleaning is the only option.

MYTH: “Dry cleaning is always better for cashmere.”
FACT: Frequent dry cleaning can expose cashmere to harsh chemicals that strip natural oils from the fibers. Gentle hand washing or appropriate machine washing often preserves cashmere’s softness better than repeated dry cleaning.

MYTH: “Cashmere pills because it’s poor quality.”
FACT: All cashmere pills to some extent—it’s a natural characteristic of the fiber, not necessarily an indication of quality. Even the finest cashmere will develop some pilling with wear, though higher-quality fibers may pill less severely.

MYTH: “Washing cashmere always causes shrinkage.”
FACT: Shrinkage occurs primarily due to heat, agitation, and alkaline detergents—not water itself. Using cold water, gentle agitation, and proper pH-neutral detergents minimizes risk.

FAQs About Washing Cashmere

How often should I wash my cashmere sweater?
Typically, every 3-5 wears is sufficient unless the garment is visibly soiled or has absorbed odors. Overwashing can accelerate wear, while underwashing allows oils and dirt to damage fibers.

Can I use regular detergent in a pinch?
In an emergency, you can use a small amount of mild, dye-free, fragrance-free detergent, but avoid anything containing enzymes or brighteners. Baby shampoo is a safer alternative when proper wool wash isn’t available.

Does cashmere get softer after washing?
Yes, properly washed cashmere often feels softer as gentle washing removes dust and restores the natural loft of the fibers. However, harsh washing can have the opposite effect.

Why does the care label say ‘dry clean’ if water washing is possible?
Manufacturers often recommend dry cleaning as a precaution to avoid liability for damaged garments. It’s the safest general recommendation, though many cashmere items respond well to gentle water washing.

Can I iron my cashmere after washing?
Ironing is generally unnecessary if cashmere is properly reshaped while damp. If needed, use the wool setting with a pressing cloth between the iron and garment, and never apply direct heat.

How can I remove strong odors from cashmere?
For persistent odors, air the garment outdoors (away from direct sunlight) for several hours. For stronger odors, add 1/4 cup of white vinegar to the rinse water during hand washing, then rinse thoroughly.

Will washing affect the color of my cashmere?
High-quality cashmere with proper dyes should maintain color when washed correctly in cold water. Some initial slight color release may occur in the first wash, which is why washing with similar colors is recommended.

Our cashmere vests come in a variety of colors that maintain their vibrancy when cared for properly using these guidelines.
