How to wash a merino wool blanket? Complete care guide

If you’ve invested in a quality wool blanket, you’ve probably wondered how to keep it in perfect condition for as long as possible. Proper washing is essential to maintain the softness, insulation properties and impeccable appearance of wool, but many people hesitate to wash it at home, fearing it could damage the fabric.

The good news is that caring for a wool blanket doesn’t require fancy equipment or expensive specialty products. With the right techniques and a few simple rules, you can wash your blanket at home, saving time and money in the long run. In this guide, you’ll discover everything you need to know about washing and caring for wool blankets, from optimal washing frequency to correct drying and storage methods.

Why does merino wool need special care?

Merino wool is one of the finest and most delicate natural fibers. Its unique structure of microscopic scales gives it remarkable properties: it regulates temperature, repels odors and absorbs moisture. It’s precisely these characteristics that make washing wool blankets so careful care is needed to prevent shrinkage or damage to the fibers.

Unlike synthetics, merino wool is a fiber that reacts to sudden temperature changes and excessive rubbing. A well-cared-for merino wool blanket retains its fluffiness, softness and thermal insulation properties for years.

When should the wool blanket be washed?

One of the exceptional qualities of wool is that it does not require frequent washing. Natural fibers have self-soothing and antibacterial properties, so your blanket won’t accumulate unpleasant odors like synthetic textiles.

In general, it is recommended to wash your wool blanket a few times a year. For freshening between washes, airing outdoors and light shaking is sufficient. Exposure to fresh air for a few hours reactivates the fibers and eliminates any residual odor.

Washing methods for merino wool blankets

Hand washing – recommended method

Hand washing is the safest method for your fleece blanket. Here are the steps to follow:

Preparation: Fill a large tub or basin with cold or lukewarm water, no warmer than 30°C. Hot water is not suitable for wool as it causes the fibers to shrink. Add a special wool detergent or mild shampoo. Avoid products with enzymes or bleach.

Soaking the blankets: Allow the blanket to completely submerge in the water, pressing gently to allow the washing solution to soak into the fiber. Do not rub, twist or shake the blanket violently. Movements should be gentle and controlled, gently pressing the fabric to remove impurities.

Duration: Soak the blanket for 10-15 minutes maximum.

Rinsing: Empty the water and rinse the blanket with clean cold water until the rinse water becomes clear. Press gently to remove excess water without squeezing or twisting the fabric.

Car washing – with precautions!

If your washing machine has a program for wool or delicate textiles, you can wash your merino wool blanket according to these strict rules:

Select the wool or delicates program, with a maximum temperature of 30°C and minimum spin or off completely. Use only special liquid wool detergent, not powder, which can settle between the fibers. Put the blanket in a protective washing bag or pillowcase to reduce friction. Do not load the machine at full capacity, the blanket should have room to move freely in the drum.

Many modern machines have dedicated wool programs with Woolmark certification, guaranteeing a safe wash. However, if your blanket is particularly delicate, hand washing is still the safest option.

How to dry a merino wool blanket properly?

Drying is just as important as washing when caring for wool blankets. Wet fibers are extremely vulnerable and can be easily distorted if not treated with care.

Water removal: After washing, place the blanket on a flat surface and gently press with absorbent towels to remove excess water. Change towels until they no longer absorb moisture. Never hang up wet blankets, as the weight of water will stretch and warp the fibers.

Drying on a flat surface: Lay the blanket on a flat surface, on a dryer or several dry towels, in a well-ventilated room away from direct heat sources. Gently return the blanket to its original shape. Turn it periodically to dry evenly on both sides.

What to avoid: Do not use electric clothes dryers, space heaters or direct sunlight, which can cause severe shrinkage and fiber damage. Also, don’t hang wet blankets on the line as they will lose their shape. Complete drying can take 24-48 hours, depending on blanket thickness and airing conditions.

Removing stains from wool blankets

Stains should be cleaned as quickly as possible before they penetrate deep into the fibers. For fresh stains, immediately dab the area with an absorbent cloth to absorb excess liquid. Never rub the stain as you will push it deeper into the fabric.

For dry stains, apply a mild solution of wool detergent diluted in cold water and dab gently with a clean cloth. Work from the edges of the stain towards the center to avoid spreading. Rinse the area with cool water and allow to dry naturally.

Proper storage of wool blankets

When not using your fleece blanket, proper storage is essential to prevent damage. Make sure the blanket is completely dry before storage to avoid mold growth. Fold it loosely and store it in a dry place out of direct sunlight.

Natural wool can attract moths, so we recommend using natural solutions such as dried lavender, cedar or peppermint. Avoid synthetic mothballs, which can leave lingering odors. If you’re storing your blanket for a long period, check it regularly and air it out to maintain freshness.

Common mistakes to avoid

Many problems with wool blankets arise from incorrect care practices. Using hot water is the most common mistake, leading to dramatic shrinkage and turning a soft blanket into a coarse, stiff material. The use of conventional laundry detergent, which contains harsh enzymes, also damages the structure of wool and impairs its natural properties.

Violent wringing or twisting of wet blankets damages the fibers and permanently deforms the product. Sun or heater drying can cause shrinkage and discoloration. Finally, washing too frequently, even when done correctly, prematurely wears out the natural fibers, reducing the life of your blankets.

When to call in a professional cleaner?

Although home laundering is possible for most wool blankets, there are situations when professional services are recommended. If your blanket has intricate embellishments, embroidery, or combinations of materials, a dry cleaner specializing in natural textiles will ensure optimal care. Difficult stains from dye, ink or grease also require professional treatments.

When choosing a cleaner, check if they have experience with natural wool textiles and if they use gentle cleaning methods. Clear communication about the composition and value of your blankets will help the specialists choose the most appropriate treatment method.
