Takeaway
Caring for your cashmere sweater is simple with these key steps:
- Always choose hand washing with a gentle, pH-neutral detergent.
- Use cool water to prevent shrinkage and fiber damage.
- Never wring or twist your cashmere; gently press out water.
- Always dry your sweater flat on a clean towel, reshaping it carefully.

How do you clean a cashmere sweater?
You clean a cashmere sweater by hand washing it gently in cool water with a specialized wool or cashmere detergent. After washing, rinse it well, gently press out excess water without wringing, and then lay it flat on a clean towel to air dry completely, reshaping it as it dries.
Why Cashmere Demands Gentle Cleaning
Cashmere wool comes from cashmere goats. Its fibers are very fine. This fineness makes cashmere soft and lightweight. It also makes the fabric delicate. Standard washing methods, like a harsh machine cycle or hot water, can damage these fibers. They can cause shrinkage, pilling, or a rough texture.
Understanding cashmere’s nature helps you care for it better. Each fiber has tiny scales. Hot water or aggressive agitation can make these scales lock together. This causes the fabric to shrink and become matted. Harsh detergents strip natural oils from the wool. This makes the sweater feel less soft. Proper cleaning methods protect the fiber’s structure. This keeps your sweater feeling luxurious and looking good for many years. It is important to treat this special fabric with care.
Essential Tools for Cashmere Cleaning
Before you start cleaning your cashmere sweater, gather all your supplies. Having everything ready makes the process smooth. You will need a few specific items to ensure a safe wash. Using the right tools protects your sweater.
First, you need a gentle detergent. Look for one specifically made for wool, delicates, or cashmere. These detergents are pH-neutral. They will not strip the natural oils from your cashmere. Avoid harsh laundry detergents or those with bleach. Next, you need a clean basin or a clean sink. Make sure it is free of any soap residue or dirt. You also need several clean, absorbent towels. These towels help remove excess water from your sweater after washing. You may also want a mesh laundry bag if you decide to machine wash on a delicate cycle, though hand washing is always preferred. Having the right tools ensures a successful cleaning process for your delicate garment.
Choosing the Right Detergent
Selecting the correct detergent is very important for cashmere. Regular laundry detergents are too strong. They often contain enzymes or harsh chemicals. These ingredients can break down cashmere fibers. This causes them to lose their softness and shape.
Always choose a pH-neutral detergent. Many brands offer special formulas for wool, silk, or cashmere. These detergents clean gently without harming the fibers. Some people even use baby shampoo for a very mild option. Read the label carefully to ensure it is safe for delicate fabrics. A good detergent helps maintain the natural lanolin in the cashmere. Lanolin is the oil that keeps cashmere soft and resilient. Using the right soap extends the life and beauty of your sweater.
Step-by-Step Guide to Hand Washing Your Cashmere Sweater
Hand washing is the safest and best way to clean your cashmere sweater. It gives you full control over the process. This gentle method protects the delicate fibers. Follow these steps carefully for a perfect wash every time.
First, prepare your washing area. Make sure your sink or basin is very clean. Fill it with cool or lukewarm water. The water should be no warmer than 85°F (30°C). Add a small amount of your chosen gentle detergent to the water. Swirl the water to dissolve the soap. Avoid putting too much detergent, as it can be hard to rinse out. Before wetting your sweater, lay it flat and gently trace its outline on a piece of paper. This outline helps you reshape the sweater accurately after washing.
Pre-Treatment and Soaking
Before washing, check your cashmere sweater for any visible stains. If you find a stain, gently pre-treat it. Apply a tiny drop of the same gentle detergent directly onto the stain. Use your fingertip to lightly pat the detergent into the spot. Do not rub, as rubbing can damage the fibers.
Once you pre-treat any stains, carefully submerge your entire sweater into the soapy water. Make sure the sweater is completely saturated. Gently squeeze it a few times to ensure the water penetrates all fibers. Let the sweater soak for no more than 5-10 minutes. Soaking helps loosen dirt without excessive agitation. Avoid leaving it in the water for too long. Long soaking times can lead to color fading or fiber damage. This short soak is enough to clean your delicate garment effectively.
Gentle Washing and Rinsing
After soaking, gently wash the sweater. Do not twist, scrub, or stretch the fabric. Instead, gently squeeze the soapy water through the sweater. Focus on areas that seem dirtier, like cuffs or the collar. Just a few gentle presses are enough. The goal is to move the water through the fibers, not to agitate them.
Once you finish washing, drain the soapy water. Refill the basin with clean, cool water. Carefully transfer your sweater to the clean water. Gently press the sweater to release the soap. Repeat this rinsing process several times. Use fresh, clean water each time until no soap suds remain. This step is crucial for preventing soap residue. Residual soap can make your cashmere feel stiff. It also helps prevent potential damage to the fibers. Remember, the key is gentle handling at every stage.
Removing Excess Water
This step is very important. You need to remove water without harming the sweater. Never wring or twist your cashmere sweater. Wringing can permanently distort the garment’s shape. It can also stretch out the fibers.
Instead, lift the sweater gently from the rinse water. Support its weight as you lift it. Hold it over the basin to let most of the water drip out naturally. Then, lay the sweater flat on a clean, dry, absorbent towel. Roll the sweater and the towel together tightly. Press down on the rolled towel to squeeze out more water. You can even stand on the rolled towel gently to apply more pressure. This method transfers the water from the sweater to the towel. Repeat this process with a second dry towel if your sweater is still very wet. This gentle pressing prepares your sweater for drying. The steps you use for your sweater also work for a delicate cashmere scarf.
Considerations for Machine Washing Cashmere (Use Caution)
While hand washing is the safest method, some modern washing machines have a “delicate” or “wool” cycle. This cycle uses cold water and very minimal agitation. If you choose to machine wash, extreme caution is necessary. Machine washing always carries a higher risk of damage compared to hand washing.
Always place your cashmere sweater inside a mesh laundry bag. This bag protects the sweater from stretching or snagging on the machine’s drum. Use only cold water and a wool-friendly detergent. Select the gentlest cycle available, often labeled “hand wash,” “wool,” or “delicate.” Do not use the spin cycle, or use the lowest spin setting possible. High spin speeds can stretch and damage cashmere fibers. Even with these precautions, monitor your sweater closely. Machine washing is a calculated risk. It should only be chosen if hand washing is not possible. For washing any sweater, even a light-up sweater, specific care is important.
Drying Your Cashmere Sweater Correctly
Proper drying is as important as washing for cashmere. Incorrect drying can cause your sweater to stretch, shrink, or lose its shape. Air drying flat is the only recommended method for cashmere. Never put cashmere in a clothes dryer. The high heat and tumbling action will shrink it permanently.
After removing excess water with towels, lay your sweater flat on a clean, dry towel. You can also use a mesh drying rack. These racks allow air to circulate around the garment. Carefully reshape the sweater to its original size and form. Remember the outline you traced earlier? Use it now. Gently tug and pat the sweater into the correct shape. Make sure edges and seams are straight. Position the sweater away from direct sunlight or heat sources. Turn the sweater over periodically to ensure even drying. Drying can take 24 to 48 hours, depending on humidity and sweater thickness. Patience is key for preserving your cashmere.
Spot Cleaning Common Cashmere Stains
Sometimes, you just get a small stain on your cashmere. You do not need to wash the entire sweater for a small spot. Spot cleaning can handle these minor accidents. Act quickly when a spill happens. Fresh stains are always easier to remove.
First, identify the type of stain. For liquid spills like coffee or wine, gently blot the area with a clean, dry cloth. Do not rub, as rubbing pushes the stain deeper into the fibers. For oil-based stains, you might need a tiny amount of gentle detergent. Apply it directly to the stain using a clean fingertip. Gently pat the area. Then, use a clean, damp cloth to blot away the detergent and the stain. Always test any cleaning solution on an inconspicuous area first. This ensures it does not discolor or damage the fabric. Work from the outside of the stain inward. This prevents the stain from spreading. Be patient and gentle. Repeat the process if necessary.
Storing Your Cashmere for Long-Term Care
Proper storage protects your cashmere sweater between wears. It helps maintain its shape and prevents damage from pests. Never hang your cashmere sweaters. Hanging can cause them to stretch out of shape, especially at the shoulders. The weight of the sweater will pull the fabric down over time.
Always fold your cashmere sweaters neatly. Store them in drawers or on shelves. If you store them for a long period, use breathable storage bags. Cotton garment bags are ideal. Avoid plastic bags, as they can trap moisture and cause mildew. Moths love cashmere. To protect your sweaters, use natural moth repellents. Cedar blocks, lavender sachets, or cedar balls work well. Place these items in your storage area. Remember to refresh cedar every few months by lightly sanding it. For very long-term storage, consider putting cleaned cashmere in a sealed, airtight container or bag with moth protection. This ensures your beautiful sweater stays safe and ready for its next wear.
Frequently Asked Questions
Can you put cashmere in the washing machine?
You can machine wash cashmere only if your washing machine has a dedicated “hand wash” or “wool” cycle. Use cold water and a gentle detergent. Always place the sweater in a mesh laundry bag. However, hand washing is always the safest method to prevent shrinkage or damage.
How often should I clean my cashmere sweater?
Clean your cashmere sweater only when necessary. Cashmere naturally resists odors. If you wear it occasionally, cleaning it once every three to five wears might be enough. For heavy wear or visible dirt, clean it more often. Avoid over-washing to preserve its fibers.
What detergent is best for cashmere?
The best detergent for cashmere is a pH-neutral, gentle formula made for wool, silk, or delicate fabrics. Avoid detergents with harsh enzymes, bleach, or fabric softeners. These can strip the natural oils from the cashmere, making it less soft.
How to remove pilling from cashmere?
Pilling is normal for cashmere due to fiber friction. You can remove pills using a cashmere comb or a fabric shaver. Lay the sweater flat and gently glide the comb or shaver over the affected areas. This removes the small balls of fiber without damaging the sweater.
Can I iron cashmere?
It is best to avoid ironing cashmere. The high heat can damage the delicate fibers. If you must iron, use the lowest heat setting specifically for wool or silk. Place a clean, damp cloth between the iron and the sweater. Gently press the iron; do not slide it. Steaming is a safer option for wrinkles.
How to store cashmere?
Store cashmere folded flat in a drawer or on a shelf. Never hang cashmere, as it can stretch. Use breathable storage bags if storing for extended periods. Protect your cashmere from moths using natural repellents like cedar blocks or lavender sachets. Ensure sweaters are clean before storing them.
