How to Wash a Cashmere Cardigan: A Step-by-Step Care Guide

Keeping Your Cashmere Cardigan in Perfect Condition

A cashmere cardigan is a timeless piece that combines elegance and comfort, but without proper care, it can lose its softness and longevity. Unlike regular wool or synthetic fabrics, cashmere requires special attention to maintain its delicate fibers.

Many people make the mistake of using harsh detergents or washing cashmere too frequently, which can lead to shrinkage or pilling. Understanding the right techniques can help you extend the lifespan of your cardigan while keeping it looking luxurious.

In this guide, we’ll cover everything you need to know, from the best washing methods to stain removal and proper storage. Whether you're wondering if machine washing is safe or how to handle wrinkles, these essential tips will ensure your cashmere remains a staple in your wardrobe for years to come.

Should You Dry Clean Your Cashmere Cardigan?

Dry cleaning may seem like the safest way to care for a cashmere cardigan, but it’s not always the best option. While professional cleaning removes dirt and stains effectively, the chemicals used in the process can sometimes weaken natural fibers over time.

One advantage of dry cleaning is that it prevents excessive handling, reducing the risk of stretching or distortion. However, frequent exposure to harsh solvents may strip cashmere of its natural softness, making it less plush and delicate to the touch.

Dry cleaning is recommended for tough stains or structured cashmere pieces that cannot be hand-washed. Otherwise, handwashing with a mild detergent is a safer, more gentle method that helps preserve the integrity and luxurious feel of your cardigan.

Can You Wash Cashmere in a Washing Machine?

Many people hesitate to wash a cashmere cardigan in a machine, fearing damage to the delicate fibers. While machine washing is not ideal, it can be done safely if the right precautions are taken.

To minimize the risk of stretching or pilling, always select the delicate cycle with cold water. Using a mild detergent specifically designed for wool or cashmere will help preserve the softness and prevent fiber breakdown.

For added protection, place the cardigan inside a mesh bag before washing. This prevents excessive agitation, which can cause the fabric to lose its shape. Once washed, avoid wringing it out—gently press out excess water and lay it flat to dry.

The Right Way to Hand Wash Your Cashmere Cardigan

Handwashing is the safest method to clean a cashmere cardigan, ensuring the fibers remain soft and intact. By using gentle techniques, you can prevent stretching or damage while maintaining its luxurious feel.

Step 1: Prepare the Water

Fill a clean basin or sink with lukewarm water (never above 30°C/86°F). Add a small amount of mild detergent specifically designed for cashmere. Avoid fabric softeners, as they can weaken the fibers over time.

Step 2: Submerge and Soak

Turn the cardigan inside out before placing it in the water. Gently swirl it for about a minute, then let it soak for 10-20 minutes. Avoid leaving it submerged for too long, as this can affect the delicate fibers.

Step 3: Rinse and Remove Excess Water

Drain the soapy water and refill with fresh, cool water. Gently press the cardigan to rinse out detergent—never wring or twist it. Instead, press it against the sink or use a towel to absorb excess moisture before laying it flat to dry.

Removing Stains from Your Cashmere Cardigan Safely

A spill on your favorite cashmere cardigan doesn’t have to be permanent. The key is acting quickly and using gentle methods to avoid damaging the delicate fibers.

Step 1: Blot, Don’t Rub

As soon as a stain occurs, use a clean, dry cloth or paper towel to blot the area. Rubbing can push the stain deeper into the fibers, making it harder to remove.

Step 2: Treat the Stain

For most stains, mix cold water with a small amount of cashmere-safe detergent. Dab the solution onto the stain using a soft cloth. For oil-based stains, adding a few drops of white vinegar can help break down grease without harming the fabric.

Step 3: Rinse and Dry

Gently rinse with cold water, ensuring all detergent is removed. Avoid wringing—press out excess moisture with a towel. Lay the cardigan flat to dry, reshaping it as needed.

Rescuing a Shrunken Cashmere Cardigan

Accidentally shrinking your cashmere cardigan can be frustrating, but there’s hope. With the right technique, you can gently restore its original fit without damaging the delicate fibers.

Step 1: Prepare a Gentle Soak

Fill a basin with lukewarm water and add a small amount of baby shampoo or a wool conditioner. These help relax the fibers, making them more pliable for reshaping.

Step 2: Stretch the Fabric Carefully

Submerge the cardigan and let it soak for about 30 minutes. Gently press out excess water—never wring! Lay it flat on a clean towel and carefully stretch the fabric back to its original dimensions.

Step 3: Drying for Best Results

Roll the towel with the cardigan inside to remove moisture, then lay it flat to air dry. Reshape it as needed, adjusting every few hours to maintain its form.

Safely Removing Wrinkles from Your Cashmere Cardigan

Ironing cashmere requires extra care to avoid damaging its delicate fibers. Direct heat can weaken the structure, leading to unwanted burns or flattening of the natural texture.

Step 1: Use Steam Instead of Direct Ironing

For best results, hang your cardigan and use a garment steamer at a safe distance. The steam gently relaxes wrinkles without exposing the fabric to excessive heat.

Step 2: Ironing with a Protective Layer

If you must use an iron, place a damp cloth between the cashmere and the iron. Set it to the lowest heat and press lightly—never glide the iron directly over the fabric.

Step 3: Let It Cool Before Wearing

Once wrinkle-free, lay the cardigan flat and allow it to cool completely before wearing or storing to prevent creasing.

How Often Should You Wash Your Cashmere Cardigan?

Washing cashmere too frequently can wear down its delicate fibers, reducing its lifespan. Unlike everyday fabrics, it doesn’t need to be washed after every wear.

Wash Based on Frequency of Use

If worn occasionally over a base layer, washing every four to six wears is ideal. For direct skin contact, a gentle wash after two or three wears keeps it fresh.

Airing Out Between Wears

Instead of frequent washing, let your cardigan air out overnight on a flat surface or hanger. This helps remove odors and maintain its softness.

Spot Cleaning for Minor Stains

Rather than washing the entire garment, remove small stains with a mild detergent and cold water. This prevents unnecessary fiber stress.

Keeping Your Cashmere Cardigan Smooth and Pill-Free

Even the finest cashmere can develop pills and wrinkles over time. With the right care, your cardigan will stay soft and elegant for years.

Why Pilling Happens and How to Remove It

Pilling occurs when fibers rub against each other, creating small bobbles on the surface. Use a cashmere comb or fabric shaver to gently remove them without damaging the knit.

Preventing Wrinkles and Creases

To avoid deep wrinkles, always store your cardigan flat instead of hanging it. Folding it neatly and placing tissue paper between folds helps maintain its shape.

Steaming for a Fresh Look

For stubborn creases, a fabric steamer is the safest way to relax fibers. If using an iron, place a damp cloth between the heat and your cashmere to prevent scorching.

Storing Your Cashmere Cardigan the Right Way

Proper storage is key to preserving the softness and shape of your cashmere cardigan. A few simple steps will keep it fresh and ready to wear.

Folding to Prevent Stretching

Avoid hanging cashmere, as it can lose its shape over time. Instead, fold your cardigan neatly and store it flat to maintain its structure.

Protecting Against Moths

Natural moth repellents like lavender sachets or cedar blocks help keep your knitwear safe. Avoid chemical mothballs, as they can leave strong odors.

Using Breathable Storage Bags

For long-term storage, place your cashmere in a cotton or muslin bag. This prevents moisture buildup while allowing air circulation, keeping the fibers in top condition.

Keeping Your Cashmere Cardigan Luxurious for Years

Taking care of your cashmere cardigan properly ensures it remains soft, stylish, and long-lasting. From washing techniques to careful storage, every step plays a role in maintaining its beauty.

Handwashing with a gentle detergent, using a breathable storage bag, and avoiding excessive heat are key practices to prevent damage. Regularly removing pills and storing your cardigan folded instead of hanging will help maintain its shape and texture over time.

With the right care routine, your cashmere knitwear will continue to provide warmth and elegance season after season. A little attention goes a long way in preserving the quality of this timeless wardrobe essential.
