Wool is a cozy and durable fabric, but washing it can feel tricky. You might wonder if tossing your wool sweaters or blankets into the washing machine will ruin them. The good news is you can wash wool in the washing machine—but only if you follow the right steps.
Understanding how to care for wool properly helps you avoid shrinking or damaging your favorite pieces. With the right settings and detergents, machine washing wool can be safe and convenient. Let’s explore how to keep your wool items looking fresh and lasting longer without the hassle.
Understanding Wool Fabric
Wool requires special care because of its unique fiber structure. Knowing wool’s types and reactions to water and heat helps you wash it safely in a machine.
Types of Wool and Their Characteristics
Wool comes in several types, each with distinct qualities affecting care:
- Merino Wool: Fine, soft fibers ideal for delicate garments. It resists wrinkles and retains warmth.
- Cashmere: Luxuriously soft but fragile; prone to stretching and pilling.
- Alpaca: Strong, lightweight, and less elastic, making it more durable but still sensitive to agitation.
- Shetland Wool: Coarser texture, more robust, often found in sweaters and blankets.
- Mohair: Lustrous and silky fibers that shed easily, requiring gentle handling.
Each type demands tailored washing methods to maintain texture, shape, and softness.
How Wool Reacts to Water and Heat
Wool fibers absorb water quickly but swell, which can lead to stretching if mishandled. Heat causes wool scales to lock together, resulting in felting and shrinking. Sudden temperature changes also stress fibers, increasing damage risk. Using cold water and gentle cycles prevents fiber contraction and preserves garment integrity during machine washing.
Can You Wash Wool in the Washing Machine?
You can wash wool in the washing machine if you follow specific guidelines. Machine washing preserves wool’s texture and shape only when proper care measures are in place.
Factors to Consider Before Washing
Check the care label on your wool item to confirm machine wash compatibility. Consider wool type, such as Merino or Cashmere, since delicate fibers react differently to agitation and water temperature. Avoid washing heavily soiled wool in a machine to prevent damage. Always inspect garment construction, as loosely knitted or embellished items require hand washing.
Best Washing Machine Settings for Wool
Select a gentle or wool-specific cycle to minimize agitation that causes felting. Use cold water to prevent shrinking and fiber distortion. Choose a slow spin speed below 400 RPM to reduce stretching. Opt for an extra rinse to thoroughly remove detergent without harsh mechanical stress.
Detergents Suitable for Wool
Use a mild detergent labeled for wool or delicate fabrics to protect natural fibers. Avoid bleach, fabric softeners, and harsh chemicals that weaken wool strands. Liquid detergents dissolve easier in cold water, ensuring an even clean. Measure detergent according to manufacturer instructions to prevent residue buildup.

Follow these steps to wash wool safely in your machine without risking damage or shrinkage.
Preparing the Wool Garment
Examine your wool garment’s care label for machine wash compatibility. Remove any stains with a wool-safe stain remover before washing. Turn the item inside out to protect the surface fibers. Secure buttons and zippers, and place the garment in a mesh laundry bag to reduce friction and stretching during the wash.
Selecting the Right Cycle and Temperature
Choose a wool-specific or gentle cycle on your washing machine. Set the water temperature to cold—below 86°F (30°C)—to prevent felting and shrinking. Keep the spin speed low, ideally under 400 RPM, to minimize agitation that can distort the wool fibers. Use a mild detergent formulated for wool or delicate fabrics, and avoid bleach and fabric softeners to preserve fiber strength.
Drying Wool Properly After Machine Washing
After washing, remove the garment promptly from the machine to avoid wrinkles. Lay it flat on a clean, dry towel shaped to its original dimensions for air drying. Avoid hanging wool items because this can cause stretching and misshaping. Keep the garment away from direct sunlight or heat sources like radiators to prevent fiber damage and color fading. Rotate the garment occasionally to ensure even drying.
Common Mistakes to Avoid When Washing Wool
Avoid using hot water, as it causes wool fibers to shrink and felt. Choose cold water to maintain your garment’s size and texture. Skip harsh detergents and bleach, which degrade wool fibers and reduce softness. Select a delicate or wool-specific machine cycle; regular cycles create excessive agitation that can damage wool. Do not overload the washing machine, since crowded conditions increase friction and stretching. Avoid high spin speeds above 400 RPM, which strain wool and cause misshaping. Skip tumble drying, because heat and tumbling distort wool fibers. Prevent hanging wet wool garments; instead, dry them flat to maintain their shape and avoid stretching. Neglecting care label instructions risks damage, so always check and follow the manufacturer’s guidelines precisely.
Conclusion
You can confidently wash wool in your machine as long as you follow the right steps. Choosing the proper cycle, water temperature, and detergent is key to keeping your wool garments looking and feeling their best. Always pay attention to care labels and treat each type of wool according to its unique needs.
By handling your wool with care during washing and drying, you’ll extend the life of your favorite pieces without sacrificing convenience. With the right approach, machine washing wool becomes a simple and safe part of your laundry routine.
