Yes, you can wash wool sweaters in a washing machine. Nevertheless, it is paramount to observe certain precautions to protect your garment during the washing process.

Wool is a prized material known for its ability to provide warmth, comfort, and style. Wool sweaters, therefore, are much sought after, especially during the winter season. But, these sweaters need special care, and when it comes to washing, one often asks, “Can you wash wool sweaters in a washing machine?” The answer is a resounding yes, but there are guidelines to follow to avoid damage to your garment.

Dos and don’ts of When Washing Wool Sweaters In Washing Machine


  • Always read the care label on your wool sweater before washing. Many will have specific washing instructions.
  • Use a gentle, wool-friendly detergent to protect the wool’s delicate fibers.
  • Choose the delicate cycle on your washing machine to wash your wool sweaters. This cycle is gentler on the fibers.
  • Inside out your sweater before washing to reduce pilling and protect the outer surface.
  • Use cool water for washing. Hot water can cause wool to shrink.
  • Dry your sweaters naturally. Lay them flat in a well-ventilated area out of direct sunlight or intense heat sources.


  • Avoid using bleach or fabric softener when washing your wool sweater. They can damage the wool fibers.
  • Do not wash your wool sweater with harsh fabrics, like denim. They can create friction and cause pilling.
  • Refrain from wringing out your sweater after washing. This can stretch and misshape the garment.
  • Do not wash wool sweaters excessively. Wool has natural dirt and odor-resistant properties and doesn’t require frequent washing.
  • Never tumble dry your wool sweater. The heat can lead to shrinkage and damage the fibers.

Steps to wash Wool Sweaters in the Washing Machine:

  1. Preparation: Check the care label on your sweater and turn it inside out.
  2. Load the Machine: Place your sweater in the washing machine. If possible, use a mesh laundry bag for extra protection.
  3. Detergent: Add a wool-friendly laundry detergent.
  4. Setting: Set your washing machine to the gentle or delicate cycle, and ensure the water temperature is cold or lukewarm.
  5. Washing: Start your washing machine and let it complete its cycle.
  6. Drying: Once washed, gently squeeze out any excess water from the sweater. Avoid wringing it out. Lay it flat on a clean towel in a well-ventilated area to air-dry.

Alternative Washing Methods

If you’re not comfortable machine washing your wool sweater, hand washing is a viable alternative. It is a gentler approach, thus reducing the risk of damage to your sweater. Fill a basin with cold or lukewarm water, add a wool-safe detergent, and gently agitate the sweater in the water. Rinse it thoroughly, then gently squeeze out excess water and lay it flat to dry.


Can I use regular detergent to wash my wool sweater?

Answer: No, regular detergents can be harsh on wool fibers. It’s advisable to use a wool-friendly detergent.

How often should I wash my wool sweater?

Answer: Wool doesn’t need to be washed as frequently as other materials due to its anti-bacterial properties. Washing after every five to seven wears is generally sufficient.

Why can’t I tumble dry my wool sweater?

Answer: Tumble drying uses heat, which can cause wool fibers to shrink and become damaged. Air-drying is the best method for wool sweaters.

What should I do if my wool sweater shrinks after washing?

Answer: You can try to restore a shrunk sweater by soaking it in lukewarm water and hair conditioner, then gently stretching it back to its original size. However, prevention is better than cure.

Can I iron my wool sweater?

Answer: It is not recommended to iron wool sweaters as the heat can damage the fibers. If necessary, use a steam iron on a low setting, and avoid pressing down too hard.

Final Words

Washing a wool sweater in a washing machine is feasible, but it does require careful attention. The appropriate washing methods will ensure that your sweater retains its quality, comfort, and durability. Ultimately, the little extra care is a small price to pay for the lasting warmth and fashion that a wool sweater provides.
