A knitted blanket needs more care than an ordinary throw because its loops, yarn type, and construction can change during washing.
This guide explains how to wash knitted blanket fabrics safely, so you can remove dirt, odors, and stains without ruining the shape.
Why knitted blankets need special care
Knitted blankets are often made from wool, cotton, acrylic, alpaca, or blended yarns, and each fiber reacts differently to water, heat, and agitation.
The biggest risks are stretching, shrinking, felting, pilling, and distorted stitches, especially when a blanket is wet and heavy.
Before washing, check the care label if one is attached.
If the blanket is handmade, consider the yarn content and stitch pattern, since loosely knit fabrics can snag or grow out of shape more easily than dense weaves.
What you need before you start
Gather everything first so the blanket spends less time wet than necessary.
A prepared setup helps reduce handling and protects the knit structure.
- Mild detergent designed for delicates or wool
- A clean bathtub, large basin, or washing machine with a delicate cycle
- Cool or lukewarm water
- Two or more clean towels
- A flat drying surface or drying rack
- A soft stain remover, if needed
How to tell what kind of yarn your blanket is made from
The yarn type determines the safest cleaning method.
If you know the material, you can avoid the most common washing mistakes.
Wool and wool blends
Wool is warm and durable, but it can felt when exposed to heat, friction, or sudden temperature changes.
Many wool blankets should be hand washed or machine washed only if the label specifically says machine washable.
Cotton
Cotton knitted blankets are usually easier to wash than wool, but they can still stretch when soaked.
They may also shrink if dried with high heat.
Acrylic and other synthetics
Acrylic blankets are generally more forgiving and often machine washable.
Even so, they can pill or lose their shape if washed too aggressively or dried too hot.
Cashmere, alpaca, and luxury fibers
Delicate natural fibers often need gentle hand washing with minimal agitation.
These materials can feel soft and luxurious, but they are more vulnerable to stretching and fiber damage.
How to wash knitted blanket by hand
Hand washing is the safest method for most delicate knitted blankets.
It gives you control over water temperature, movement, and drying, which helps preserve the blanket’s texture and fit.
- Fill a clean tub or basin with cool or lukewarm water.
- Add a small amount of mild detergent and mix it in gently.
- Submerge the blanket and press it down slowly until fully wet.
- Let it soak for 10 to 15 minutes.
- Gently move the blanket through the water without wringing or scrubbing.
- Drain the soapy water and refill with clean water to rinse.
- Repeat rinsing until no detergent remains.
To remove excess water, lift the blanket carefully and support its weight with both hands.
Never twist the fabric; instead, press it between your hands or against the side of the basin to release water gradually.
Can you machine wash a knitted blanket?
Yes, some knitted blankets can be machine washed, but only when the fiber content and care label allow it.
Machine washing is more suitable for sturdy cotton or acrylic blankets than for delicate wool or handmade pieces.
If machine washing is allowed, use these precautions:
- Select the delicate or wool cycle.
- Use cold water to reduce shrinkage and fiber stress.
- Place the blanket in a mesh laundry bag if it fits.
- Use a small amount of mild detergent.
- Wash the blanket alone or with similarly soft items.
- Avoid fabric softener if the care label warns against it.
Even when machine washing is safe, overloading the drum can cause twisting and uneven agitation.
A knitted blanket needs room to move gently, not be compressed with heavy laundry.
How to remove stains from a knitted blanket
Spot treating before a full wash often gives better results than trying to scrub stains later.
Work on the stain as soon as possible, but always test any cleaner on a hidden area first.
- Blot, do not rub, fresh spills with a clean cloth.
- Apply a small amount of diluted mild detergent to the stain.
- Use a soft cloth or fingertips to dab gently.
- Rinse with cool water before washing the entire blanket.
For oily stains, a tiny amount of detergent often works better than harsh stain removers.
For protein-based stains such as food or body fluids, cold water is safer than warm water, which can set the stain.
How to dry a knitted blanket without stretching it
Drying is just as important as washing because a wet knitted blanket can easily sag out of shape.
The safest approach is to remove as much water as possible first, then dry it flat.
After blotting with towels, lay the blanket flat on a clean dry towel or mesh drying rack.
Smooth it gently back to its original dimensions, but do not pull at the edges.
If you need to speed up drying, place another dry towel underneath and change it when it becomes damp.
Avoid hanging a heavy knitted blanket from a clothesline or hanger.
The weight of the water can stretch stitches permanently, especially along the edges.
What detergents are best for knitted blankets?
A mild, fragrance-free detergent is often the safest choice for knitted textiles.
Wool-safe detergents are especially helpful for natural fibers because they are formulated to clean without stripping too much oil from the yarn.
Avoid bleach, strong enzyme-heavy cleaners, and harsh stain products unless the label clearly says they are safe for the fiber type.
These products can weaken yarn, fade dye, or alter the texture of the knit.
How often should you wash a knitted blanket?
Most knitted blankets do not need frequent washing unless they are used heavily, exposed to pets, or stained.
For blankets used on a sofa or bed, washing every few months is often enough, while daily-use throws may need more regular care.
Between washes, airing the blanket outdoors in shade or near a ventilated window can help reduce odors.
Light brushing or gentle lint removal also keeps the surface cleaner without subjecting the fabric to unnecessary washing.
Common mistakes to avoid
Many blanket problems happen during washing, not because the item is old.
Avoiding a few common errors can extend the life of the knit.
- Using hot water on wool or blended yarns
- Wringing, twisting, or stretching the blanket while wet
- Using a high-spin or heavy-duty cycle
- Drying on high heat in a dryer
- Ignoring the fiber content and care label
- Scrubbing stains aggressively with a brush
How to store a knitted blanket after washing
Once the blanket is fully dry, fold it loosely and store it in a cool, dry place.
A breathable cotton storage bag works better than plastic for long-term storage because it helps prevent trapped moisture.
If the blanket is handmade, refolding it occasionally can reduce permanent creases along the same lines.
For seasonal storage, keep it away from direct sunlight, which can fade color and weaken some fibers over time.
When to seek professional cleaning
Professional textile cleaning is worth considering if the blanket is especially valuable, antique, heavily stained, or made from fibers you cannot identify.
This is also a smart option for oversized knitted blankets that are too heavy to wash safely at home.
If a blanket has embroidery, mixed materials, or delicate decorative elements, a cleaner experienced with specialty fabrics can reduce the risk of damage.
That can be especially useful for heirloom throws and hand-knit gifts.
