Summary

The best way to clean wool socks is to follow the care label, use a gentle wool or delicate cycle with cool water when machine washing is allowed and choose a mild detergent designed for wool. Hand washing is another gentle option for socks labeled for hand washing. Wool socks should generally be turned inside out before washing and dried according to their care instructions to help preserve their shape, softness and performance.

Wool socks are valued for their comfort, moisture management and ability to stay fresh between washes. With the right care routine, you can keep your favorite pairs feeling comfortable while helping them last longer.

What Is the Best Way to Wash Wool Socks?

The best way to wash wool socks is to use the care instructions provided by the manufacturer and a gentle washing method.

Before washing, turn your wool socks inside out to help protect their appearance and reduce wear on the outside of the fabric. If the socks are machine washable, Woolmark recommends using a wool cycle or a cold delicate cycle when a wool setting is unavailable.

Choose a mild detergent specifically intended for wool or other delicate fabrics. Woolmark recommends avoiding heavy-duty detergents, enzyme-based detergents and bleach because they can be too harsh for wool fibers.

For a simple washing routine, keep these steps in mind:

  • Check the care label before washing.

  • Turn the socks inside out.

  • Use a wool or delicate cycle if machine washing is permitted.

  • Choose a mild wool detergent.

  • Avoid bleach and harsh detergents.

Can You Hand Wash Wool Socks?

Hand washing is a gentle option for wool socks that are labeled for hand washing.

Fill a basin with clean lukewarm water and add a mild wool detergent. Woolmark recommends soaking hand-wash-only wool socks for about 10 minutes before rinsing them thoroughly first with lukewarm water then with cold water.

Avoid aggressively scrubbing, twisting or wringing the socks because excessive handling can put unnecessary stress on the fibers. Instead, gently move the socks through the water and press out excess moisture when you're finished rinsing.

For hand washing, follow these basic guidelines:

  • Use lukewarm water rather than hot water.

  • Choose a mild wool detergent.

  • Allow the socks to soak for about 10 minutes.

  • Rinse thoroughly.

  • Handle the socks gently while wet.

How Should You Dry Wool Socks?

The best way to dry wool socks depends on the instructions on their care label.

After washing, avoid assuming that every wool sock can safely go into a hot dryer. Some wool products are specifically designed for tumble drying while others should be dried another way. Woolmark advises that wool products without a tumble-dry instruction should be flat dried.

When air drying is recommended, place the socks in a suitable location where they can dry naturally. Avoid applying unnecessary heat unless the manufacturer's instructions specifically allow it, as following the care label is the safest way to protect the garment.

How Often Should You Wash Wool Socks?

Wool socks often do not need to be washed after every wear because wool is naturally odor resistant.

Woolmark notes that wool socks can often be worn multiple times between washes when they are aired out between uses. This can be particularly convenient when traveling or participating in multi-day outdoor activities.

How frequently you wash your socks ultimately depends on how heavily you use them. Hiking, running, hot weather and other activities that produce significant perspiration may mean you need to wash them more frequently. If the socks are visibly dirty or no longer feel fresh, it's time to wash them.
