Fear not, for with the right techniques, you can keep your crocheted wool blanket looking and feeling wonderful for years to come. So, how to wash a wool blanket properly?

How to Wash a Wool Blanket

Understanding of Wool

Before diving into the washing process, it’s crucial to understand wool as a material. Wool is a fascinating and versatile natural fiber, renowned for its unique properties and benefits. To understand how to wash a wool blanket and care for other woolen items properly, it’s helpful to delve deeper into what makes wool so special:

  1. Natural Origin: Wool is primarily obtained from sheep, but can also come from goats (cashmere and mohair), alpacas, and even camels. Each type has distinct characteristics, but all share some common woolen traits. Also, check out our article about yarns: Best Yarn for Crochet: A Stitcher’s Guide.
  2. Hygroscopic Nature: Wool can absorb moisture without feeling wet. It can take in approximately 30% of its weight in moisture, which is why woolen garments are great for insulation and moisture-wicking. This property also makes wool blankets comfortable in various climates.
  3. Temperature Regulation: Wool fibers naturally regulate temperature. They create tiny air pockets that retain heat in colder conditions and release heat when it’s warm. This makes woolen blankets ideal for year-round use.
  4. Durability and Elasticity: Wool fibers are naturally elastic and can stretch up to 50% when wet and 30% when dry. They also have a natural crimp, which gives them a ‘springy’ quality and resilience. This elasticity helps woolen items retain their shape and resist wrinkles.
  5. Flame Resistance: Wool is naturally flame-resistant, making it a safer choice for bedding materials. It has a higher ignition threshold compared to many other fibers and tends to char rather than flare up.
  6. Antibacterial and Odor-Resistant: Wool has natural antibacterial properties, partly due to its ability to manage moisture. Bacteria often struggle to thrive in wool, reducing odors and making it more hygienic.
  7. Sensitivity to Alkaline Substances: Wool is sensitive to alkalines, which can break down its fibers. This is why using a pH-neutral or slightly acidic detergent is crucial when washing wool.
  8. Prone to Felting: When wool is exposed to heat, moisture, and agitation, its fibers can interlock and mat together, a process known as felting. This is irreversible and can lead to shrinkage and hardening of the wool. Hence, gentle handling during washing is essential.
  9. Biodegradable and Sustainable: Wool is a renewable resource and biodegradable, making it an environmentally friendly choice. The production of wool also tends to have a lower environmental impact compared to synthetic fibers.
  10. Variety in Quality: The quality of wool can vary greatly, with factors like the animal’s breed, age, diet, and living conditions playing a role. Finer wool like Merino is softer and less itchy, while coarser wool is more durable but may not be as comfortable against the skin.

Understanding these properties can not only guide you in how to wash and care for your wool blanket but also in appreciating the value and uniqueness of your hand-crafted piece. Wool’s natural resilience, combined with proper care, ensures that your blanket remains a cherished item for years.

Step-by-Step Guide to How to Wash Your Crocheted Wool Blanket

  1. Save the Yarn Label: If your wool yarn came with a label, that’s your best starting point, so make sure you save it. Follow any specific instructions provided. Consider attaching any relevant markets to your blanket – there are plenty of ready-made labels available online.
  2. Spot Cleaning: For small stains or spills, spot cleaning is often the safest option. Use a mild detergent and cold water, and gently dab at the stain without rubbing.
  3. Preparing for a Full Wash:
    • Machine Washing (If Applicable): If your blanket is machine-washable, use the gentlest cycle, cold water, and a wool-specific detergent. Place the blanket in a mesh laundry bag to reduce agitation.
    • Hand Washing: Fill a basin with cold water and add a wool-friendly detergent. Submerge the blanket and gently swirl it in the water. Avoid rubbing or wringing, as this can damage the fibers.
  4. Rinsing: Drain the soapy water and refill the basin with clean, cold water for rinsing. Gently press the water out of the blanket. Repeat this process until the water runs clear.
  5. Drying: Avoid wringing out the water as it can distort the shape. Instead, gently press out the excess water. Lay the blanket flat on a clean, dry towel, and roll it up to absorb more water. Unroll and then lay the blanket flat on a dry towel or a mesh drying rack away from direct heat and sunlight. Reshape it as needed and let it air dry completely.

Tips for Maintaining Your Wool Blanket

Maintaining a wool blanket, especially one that is hand-crocheted, requires attention to detail to ensure its longevity and to preserve its quality. Here are some tips for maintaining your wool blanket:

  1. Regular Cleaning: Lightly clean your wool blanket regularly to reduce the need for deep cleaning. Gently shake it outside to remove dust and air it out. This prevents accumulation of dirt and odors.
  2. Dealing with Pilling: Wool blankets may develop small balls of fiber or ‘pills’ over time. Use a wool comb or a fabric shaver to gently remove these pills. Be careful not to pull too hard on the fibers to avoid damaging the blanket.
  3. Storing Properly: When not in use, store your wool blanket in a cool, dry place. Avoid plastic bags as they can trap moisture; instead, use breathable cotton storage bags. Including a few cedar balls can help deter moths and other insects.
  4. Protecting from Moths and Insects: Wool is prone to moth damage. Regularly inspect and clean your blanket. Natural repellents like lavender sachets or cedar blocks can be effective in warding off moths without damaging the wool.
  5. Managing Sunlight Exposure: While airing out your blanket, avoid prolonged exposure to direct sunlight. UV rays can fade colors and weaken fibers over time. Air it in a shaded, well-ventilated area instead.
  6. Avoiding Heavy Loads: Don’t place heavy objects on top of your wool blanket for extended periods. This can compress and distort the fibers, leading to a loss of shape and texture.
  7. Immediate Attention to Spills: If you spill something on your blanket, act quickly. Blot, don’t rub, the spill with cold water and a clean cloth. For tougher stains, a mild wool detergent can be used, but spot test it first.
  8. Avoiding Harsh Chemicals: Never use bleach or harsh chemicals on wool. These can break down wool fibers and cause irreversible damage.
  9. Professional Cleaning: If your blanket is heavily soiled or if you’re unsure about washing it yourself, consider professional cleaning. Look for a cleaner who specializes in wool or delicate fabrics.
  10. Mindful Use: Be cautious with activities that can snag or tear the wool, like wearing sharp jewelry or having pets with sharp claws near the blanket.


Washing a hand-crocheted wool blanket doesn’t have to be a source of anxiety. With these steps, you can confidently clean your blanket, preserving its beauty and craftsmanship. Remember, gentle handling is key. Treat your wool blanket with care, and it will remain a source of warmth and pride for many years.
