Learn how to wash wool blanket safely at home with expert-approved hand-wash and machine-wash methods. Avoid shrinking, damage, and odors with this complete guide.

Understanding Wool Fabric and Why Care Matters

Wool is a natural fiber known for its warmth, breathability, and durability. However, it also requires gentle care. If you’ve ever wondered how to wash wool blanket properly, you’re not alone—many people fear shrinking or ruining it.

Natural Properties of Wool Fibers

Wool fibers are elastic and coated with lanolin, a natural oil that repels dirt and odors. This means wool blankets don’t need frequent washing and often just need airing out.

Why Wool Shrinks or Felts Easily

Heat, friction, and agitation cause wool fibers to interlock, a process called felting. Once this happens, the blanket shrinks permanently. That’s why gentle handling is key.

How to Wash Wool Blanket the Right Way (Overview)

Before washing, always check the manufacturer’s care label. Some wool blankets are labeled “dry clean only,” while others allow hand or machine washing.

Read the Care Label First

The care tag tells you whether water washing is safe. Ignoring it is the fastest way to damage your blanket.

Choosing the Right Detergent

Use a wool-safe or mild detergent. Regular detergents are too harsh and strip natural oils. Popular wool detergents are enzyme-free and pH-balanced (for example, Woolmark-approved detergents

Hand Washing a Wool Blanket (Safest Method)

Hand washing is the safest and most recommended way when learning how to wash wool blanket at home.

Step-by-Step Hand Washing Process

Fill a bathtub or large basin with cold or lukewarm water.
Add a small amount of wool detergent and mix gently.
Submerge the blanket fully—do not twist or scrub.
Gently press the water through the fabric for 5–10 minutes.
Drain the water and refill with clean water to rinse.
Press out excess water carefully (never wring).

Common Hand-Washing Mistakes to Avoid

Using hot water
Scrubbing stains aggressively
Letting the blanket soak for too long

Machine Washing a Wool Blanket (When Allowed)

Some modern wool blankets are machine-washable.

Washing Machine Settings for Wool

Use the wool or delicate cycle
Cold water only
Lowest spin speed

Using a Laundry Bag for Protection

Place the blanket in a large mesh laundry bag to reduce friction and stretching.

Drying a Wool Blanket Without Shrinking

Drying is just as important as washing when learning how to wash wool blanket safely.

Air Drying vs Tumble Drying

Air drying is best. Lay the blanket flat on a clean towel, away from direct sunlight or heat. Avoid tumble dryers unless the label explicitly says it’s safe.

How to Reshape Wool While Drying

Gently pull the blanket back into its original shape while damp. This prevents warping and uneven edges.

Removing Odors, Stains, and Pet Hair

Spot Cleaning Wool Safely

Blot stains with cold water and a tiny amount of wool detergent. Always test on a hidden area first.

Dealing With Tough Smells

For odors, sprinkle baking soda lightly, let it sit for an hour, then shake it off. Airing outdoors also works wonders.

How Often Should You Wash a Wool Blanket

Wool blankets typically only require washing once or twice a year, unless they become heavily soiled. Frequent washing shortens their lifespan.

Storing a Wool Blanket After Washing

Ensure the blanket is completely dry. Store it folded in a breathable cotton bag with cedar blocks or lavender to repel moths.
