While many people believe wool blankets can’t be machine washed, you actually can clean them safely in your washer with the right approach. Textile experts confirm that modern washing machines offer gentle enough cycles to handle wool, but you’ll need specific settings and supplies to prevent damage. From water temperature to spin speed, several critical factors determine whether your wool blanket survives the wash – or ends up as a shrunken, felted mess that’s half its original size.
Understanding Your Wool Blanket’s Care Label
Before washing your wool blanket, you’ll need to carefully check the care label for specific cleaning instructions and restrictions. The label contains essential information about water temperature, spin cycle settings, and whether machine washing is safe for your wool fiber.
Look for these key symbols on your care label:
- Machine washable symbol (washing machine icon)
- Temperature recommendation (30°C/86°F is typical for wool)
- Gentle cycle indicator
- “Dry flat” or “Do not tumble dry” warnings
- Wool-specific detergent or mild liquid soap
- Mesh laundry bag (at least 24″ x 36″)
- White vinegar for the rinse cycle
- Clean white towels for drying
- Cold water setting (30-40°F)
- Gentle or wool cycle option
- Low spin speed
- Drying rack or flat surface
- Fabric softener (wool-specific only)
- Clean spray bottle for spot-treating
- Measuring cup for precise detergent amounts
- Set your washing machine to cold water (40°F/4°C) and gentle cycle
- Add your wool-specific detergent – use only 1 tablespoon per blanket
- Place your wool blanket loosely in the machine, ensuring even distribution
- Start the cycle and let it run completely
- Remove promptly when finished to prevent wrinkles
- Never put your wool blanket in the dryer, as heat can cause shrinkage and damage
- Gently squeeze out excess water without wringing or twisting
- Lay the blanket flat on a clean white sheet or mesh drying rack
- Reshape the blanket to its original dimensions while damp
- Allow 24-48 hours for complete air drying
- Using hot water – For effective shrinkage prevention, never wash wool above 85°F
- Agitating too vigorously – Excessive movement causes felting and fiber damage
- Skipping temperature control checks – Always test water temp before washing
- Using regular detergent – Standard cleaners are too harsh for wool fibers
- Wringing or twisting – This distorts the fabric’s natural shape
- Hanging wet wool – The weight stretches fibers permanently
- Brush your blanket gently with a soft-bristled brush every 2-3 weeks to remove surface dirt
- Air your blanket outdoors for 20 minutes monthly, avoiding direct sunlight
- Store in a breathable cotton bag when not in use
- Rotate your blanket’s position every few weeks to distribute wear evenly
- Spot clean stains immediately with cold water
- Keep away from heat sources
- Use cedar blocks in storage to deter moths
- Fold differently each time to prevent permanent creases
If you don’t see clear fabric care instructions or the label is missing, contact the manufacturer through their website or customer service line. Some wool blankets are labeled “dry clean only” – in this case, machine washing could permanently damage your blanket’s fibers and structure.
Essential Supplies for Machine Washing Wool
Gathering the right supplies guarantees your wool blanket stays soft and undamaged during machine washing.
You’ll need:
For detergent selection, choose products labeled “wool-safe” or “gentle on delicates.” As wool care expert Sarah Thompson notes, “Regular detergents can be too harsh and strip wool of its natural oils.”

Step-by-Step Machine Washing Guide
Now that you’ve assembled your supplies, let’s put them to good use with a proper wool blanket washing routine. Follow these machine washing tips for ideal wool blanket care:
“The key to successful wool blanket washing is minimal agitation and immediate removal after the cycle ends,” notes textile expert Sarah Matthews. Remember to skip the spin cycle – excess wringing can damage wool fibers. If your machine has a wool setting, use it instead of the regular gentle cycle.
Proper Drying Techniques for Wool Blankets
While machine washing your wool blanket requires gentle care, proper drying techniques are equally important for maintaining its shape and softness.
For ideal wool care, follow these key steps:
“Air drying is vital for wool fiber preservation,” says textile expert Sarah Collins. “Position your blanket away from direct sunlight and heat sources, maintaining good airflow.” If needed, flip the blanket once during drying to guarantee even moisture evaporation. You’ll know it’s completely dry when it feels room temperature throughout.
Common Mistakes to Avoid When Washing Wool
Learning proper wool care takes practice, but knowing what not to do can help protect your blankets from costly damage. Here are the most common mistakes you’ll want to avoid:
“Most wool damage occurs from improper handling rather than the washing itself,” explains textile expert Sarah Chen. “When you follow correct temperature and gentle handling guidelines, machine washing can be safe for wool blankets.”
Tips for Maintaining Wool Blanket Quality
To keep your wool blankets looking and feeling their best between washes, proper maintenance makes all the difference. Follow these wool care tips to maximize your blanket’s longevity:
“Regular maintenance between washes can extend wool blanket longevity by up to 5 years,” notes textile expert Sarah Miller. Remember to:
Frequently Asked Questions
How Often Should I Wash My Wool Blanket?
Like a garden that needs periodic tending, your wool blanket requires care. You should wash it every 3-6 months following proper cleaning methods, unless there’s visible dirt or spills requiring immediate attention.
Can I Wash Multiple Wool Blankets Together in the Machine?
Don’t wash multiple wool blankets together as they’ll become too heavy and may damage each other. For proper wool blanket care, wash them separately using gentle washing techniques.
Will Washing Wool Blankets Make Them Less Itchy?
Over 85% of wool-related itchiness comes from shorter fibers. You’ll reduce itchiness factors through proper wool blanket care, including gentle washing and fabric softener, which helps smooth rough fiber ends.
Do Different Types of Wool Require Different Washing Temperatures?
Yes, different wool types need specific washing methods. You’ll want to use cold water for merino and cashmere, while coarser wools can handle lukewarm temperatures around 85°F (30°C).
Can I Use Regular Fabric Softener on My Wool Blanket?
With 78% of wool damage caused by harsh chemicals, you shouldn’t use regular fabric softener on wool. Instead, try fabric softener alternatives like white vinegar or specialized wool care tips recommend lanolin-based conditioners.
