Wash your knitted blanket by hand in cool water with gentle detergent, or use your washing machine's delicate cycle if the yarn label permits it

A knitted blanket needs gentler treatment than everyday laundry because the interlocked loops of yarn can stretch, felt, or pill if you use hot water, rough agitation, or harsh soap. The safest method is hand washing in cool water with a mild detergent made for wool or delicates. If your blanket's yarn label says it is machine-washable, you can use a washing machine set to a delicate or hand-wash cycle with cold water, but hand washing gives you more control and extends the blanket's life.

Before you wash, check the yarn label attached to your blanket or look for a tag sewn into a seam. The label tells you the fiber content (wool, cotton, acrylic, or a blend), the recommended water temperature, and whether machine washing is safe. If there is no label, treat the blanket as if it contains wool and use the hand-washing method below.

Key Takeaways

  • Always check the yarn label for fiber content and washing instructions before you start, because different fibers need different water temperatures and detergents.
  • Hand washing in cool water with wool-specific or delicate detergent is the safest method for any knitted blanket and prevents stretching and pilling.
  • Never wring or twist a wet knitted blanket; instead, gently squeeze out water and roll it in a towel to remove excess moisture.
  • Lay the blanket flat to dry on a clean, dry surface away from direct heat and sunlight, which can fade colors and damage fibers.
  • If you use a washing machine, choose the delicate or hand-wash cycle with cold water and place the blanket in a mesh laundry bag to reduce agitation.

Hand Washing a Knitted Blanket Step by Step

Fill a sink or basin with cool water—around 65 to 75 degrees Fahrenheit is ideal. Add a small amount of wool-specific detergent or a gentle detergent made for delicate fabrics. Brands like Woolite, The Laundress Delicate Wash, or Dreft are designed not to strip natural oils from fibers. Do not use regular laundry detergent, which is too harsh and can leave residue in the yarn.

Submerge the blanket in the soapy water and gently press it down so the water soaks through all the layers. Let it soak for 10 to 15 minutes. Do not agitate, scrub, or wring the blanket. Instead, gently squeeze the soapy water through the fibers by pressing the blanket against the sides of the sink with your hands. After soaking, drain the sink and rinse the blanket under cool running water, gently squeezing as you go, until the water runs clear and no soap remains.

To remove excess water, gently squeeze the blanket without wringing or twisting it. Lay it flat on a clean, dry towel and roll the towel up with the blanket inside, pressing gently to absorb moisture. Unroll and transfer the blanket to a second dry towel or a clean, flat surface to dry completely.

Machine Washing When the Label Allows It

If the yarn label says the blanket is machine-washable, place it inside a mesh laundry bag before putting it in the washer. The bag protects the blanket from the drum's friction and reduces the risk of snagging or pilling. Set the machine to a delicate, hand-wash, or wool cycle with cold water. Use the same mild detergent you would for hand washing—about half the amount you would use for a regular load.

Do not use the spin cycle, which can stretch and distort the blanket. Instead, select a gentle or no-spin option if your machine has one. If your machine does not have that option, stop the cycle before the spin phase begins and remove the blanket while it is still wet. Never use hot water, bleach, or fabric softener, all of which can damage knitted fibers.

Drying Your Knitted Blanket Correctly

Lay the blanket flat on a clean, dry surface to dry. A spare bed, a clean floor, or a drying rack works well. Smooth out any wrinkles or bunches gently with your hands as it dries. Do not hang the blanket to dry, because the weight of the wet yarn will stretch it out of shape. If you need to dry it faster, place a fan nearby to circulate air, but do not point the fan directly at the blanket.

Keep the blanket away from direct sunlight and heat sources like radiators or vents. Sunlight can fade colors over time, and heat can damage fibers and cause uneven drying. Depending on the blanket's size and thickness, drying may take 24 to 48 hours. The blanket is ready to use once it feels completely dry to the touch.

Dealing with Pilling and Fuzz

Pilling—small balls of fiber that form on the surface—is common in knitted blankets, especially those made from wool or wool blends. Pilling does not mean the blanket is damaged; it is a normal result of wear and friction. To remove pills, use a fabric comb, a sweater stone, or a specialized de-pilling tool. Gently brush the surface of the blanket in one direction, and the pills will roll up and come away.

Do not use a razor blade or scissors, which can cut the yarn and create holes. If pilling is severe or widespread, a de-pilling machine designed for textiles can remove pills more efficiently than hand tools. After removing pills, the blanket will look fresher and feel smoother.

Choosing the Right Detergent for Your Blanket's Fiber

The fiber content of your blanket determines which detergent works best. Wool and wool-blend blankets need a detergent labeled for wool or delicates, because regular detergent can cause the fibers to felt—a process where the scales on the yarn lock together and the fabric becomes stiff and matted. Cotton blankets can use a gentle detergent but still benefit from cool water and a delicate cycle. Acrylic blankets are more forgiving and can tolerate slightly warmer water and regular gentle detergent, but cool water and a delicate detergent still extend their life.

Avoid detergents with enzymes, which break down fibers, and steer clear of products labeled "heavy-duty" or "all-purpose." If you are unsure which detergent to buy, look for one that says "wool-safe," "delicate," or "for hand-washing" on the label. These are formulated to clean without damaging fibers.

Storage and Maintenance Between Washes

Knitted blankets do not need to be washed after every use. Airing them out on a clothesline or hanging them over a chair for a few hours between uses refreshes them and removes odors without the stress of washing. Spot-clean small stains with a damp cloth and a tiny amount of mild detergent before they set in.

When storing your blanket, fold it loosely and place it in a breathable cotton bag or pillowcase rather than a plastic container, which can trap moisture and encourage mildew. Keep it in a cool, dry place away from direct sunlight. If you store it for a long time, refold it every few months to prevent permanent creases.

Frequently Asked Questions

Can I use regular laundry detergent on my knitted blanket?

Regular detergent is too harsh and can strip natural oils from the yarn, leaving it stiff and dull. It may also cause wool to felt or leave residue that is hard to rinse out. Always use a detergent labeled for wool, delicates, or hand-washing instead.

What should I do if my blanket shrinks after washing?

Shrinkage usually happens when wool is exposed to hot water or the dryer. If it has already shrunk, you cannot reliably reverse it. To prevent shrinkage, always use cool water and air-dry flat. If the label says the blanket is machine-washable, follow those instructions exactly.

Is it safe to dry a knitted blanket in the dryer?

No. Heat from the dryer can damage fibers, cause shrinkage, and melt synthetic yarns. Always air-dry your blanket flat. The only exception is if the yarn label specifically says the blanket is dryer-safe, but even then, use the lowest heat setting.

How often should I wash my knitted blanket?

Wash your blanket every few months or when it visibly needs it, depending on how often you use it. Frequent washing wears out fibers faster, so air it out between uses instead. Spot-cleaning stains as they happen reduces the need for full washes.

Can I use fabric softener on my knitted blanket?

No. Fabric softener coats fibers and can make them feel stiff or greasy over time. It can also reduce the blanket's ability to regulate temperature. Gentle detergent and cool water are all you need to keep the blanket soft and comfortable.
