How to Wash Merino Wool


Understanding Merino Wool

What Is Merino Wool?

Merino wool is a type of wool from merino sheep that naturally regulates body temperature and wicks away moisture. It has a finer diameter than other types of wool, which makes it soft and comfortable to wear. Here are a few key points to keep in mind:

  • Merino wool is hypoallergenic, making it ideal for people with sensitive skin.
  • It is available in different grades, including ultrafine, superfine, and medium, depending on the diameter of the fiber.
  • Merino wool is commonly used in activewear, outdoor clothing, and luxury garments for its superior performance and comfort.

Advantages And Disadvantages Of Merino Wool

Like any other fabric, merino wool has its advantages and disadvantages. Here are some of the key points you should know before purchasing merino wool clothing:


  • Soft and comfortable: Merino wool fibers are finer than other types of wool, making it extremely soft to the touch.
  • Regulates body temperature: Merino wool is naturally insulating, which helps to keep you warm in cold weather and cool in warm weather.
  • Moisture-wicking: Merino wool can absorb up to 30% of its weight in moisture, making it an ideal fabric for activewear and outdoor clothing.
  • Odor-resistant: The natural properties of merino wool make it resistant to odors, even after prolonged use.


  • Expensive: Merino wool is more expensive than other types of wool, making it a luxury fabric.
  • Delicate: Merino wool is prone to pilling and can lose its shape if not cared for properly.
  • Can shrink: High heat can cause merino wool to shrink, so it’s important to wash it correctly.

Why It Requires Special Care?

Merino wool requires special care because of its delicate nature. Here are some key points to keep in mind when washing merino wool garments:

  • Hand wash or use a gentle cycle: Machine-washing merino wool can cause it to lose its shape and texture, so it’s best to hand wash or use a gentle cycle.
  • Use cold water: Hot water can cause merino wool to shrink, so it’s important to use cold water when washing.
  • Use a gentle detergent: Harsh detergents can damage the delicate fibers of merino wool, so it’s important to use a gentle detergent designed for wool.
  • Dry flat: Merino wool garments should be dried flat to prevent them from losing their shape.
  • Avoid direct sunlight: Direct sunlight can cause merino wool to fade, so it’s best to dry it in a shaded area.

Preparing For Wash

Checking The Cleaning Label

Before washing your merino wool clothing, it is crucial to check the cleaning label. The label will guide you on the ideal temperature, washing and drying method to use without damaging your clothes. Recommendations can vary from brand to brand, so it is essential to take note of the label’s instructions.

All garments should have a cleaning label to help you identify the suitable cleaning method. The best way to care for your clothes is to follow the cleaning instructions specified on the clothing label.

Sorting And Separating Merino Wool Clothing

Sorting and separating your merino wool clothing before washing is essential. The sorting includes separating light-colored clothes from dark-colored clothes. Sort the clothes by the temperature recommended on the label, separating them into hot or cold water wash. Doing this will ensure the clothes are not damaged and that the colors do not bleed during washing.

If possible, it is advisable to wash merino wool clothing separately from other non-wool items.

Pre-Treating Stubborn Stains

Pre-treating stubborn stains is crucial before washing merino wool clothing. Use a stain remover or a mild detergent to rub the stain gently. You can use a soft brush to help work the stain remover into the stained area. Leave the solution to saturate the stained area for about 10 minutes before washing.

It is best to pre-treat the stain as soon as possible before it sets in. Pre-treat the stain only on the affected area, not the entire garment. Remember to rinse the garment with clean water after pre-treatment to remove any remaining stains or detergent residue.

By adhering to these steps, you can adequately prepare your merino wool clothing for washing, ensuring that your garments last longer, and retain their colors and softness.

Choosing The Right Washing Method

Merino wool is a premium fabric that is known for its softness, warmth, and breathability. However, it can be tricky to maintain its quality and texture. Choosing the right washing method is crucial to keep your merino wool clothing in pristine condition.

Hand Wash Merino Wool

Hand washing is the most gentle way to clean merino wool, as it preserves the fabric’s delicate fibers and prevents shrinkage. Here are some steps to follow:

Best Practices For Cleaning Merino Wool

Merino wool is a luxurious material that is naturally soft, breathable, and moisture-wicking. However, cleaning merino wool requires some extra care to ensure it remains in good condition for years to come. Here are some best practices for cleaning merino wool that will help you keep your favorite merino wool garments looking new and feeling great.

Correct Water Temperature For Merino Wool

Merino wool is sensitive to temperature, and it’s essential to use the right water temperature when washing it. Follow these tips to ensure you are using the correct water temperature for your merino wool garments:

Choosing The Right Detergent

Choosing the right detergent is crucial when washing merino wool. You should use mild detergents specifically designed for wool to avoid damaging the fibers. Follow these tips to ensure you are choosing the right detergent for your merino wool garments:

  • Look for wool-specific detergents that are ph-neutral and contain no enzymes or bleach.

Drying And Storing Merino Wool

Different Drying Methods For Merino Wool

After washing your merino wool, you must dry it properly to avoid getting it stretched, felted or misshaped. Below are different drying methods you can use:

  • Flat drying: This method involves laying your merino wool on a clean towel, reshape it to its original size and let it air dry. Once it’s dry on one side, flip it over to dry on the other.
  • Hanging drying: You can also hang your merino wool to air dry. However, you must avoid using clothespins to avoid leaving marks on the fabric. Instead, you can use a padded hanger.
  • Spin drying: Using a washing machine’s spin cycle in place of the dryer reduces moisture and speeds up the drying process, but may stretch and misshape your wool.

Guidelines For Storing Merino Wool

How you store your merino wool significantly impacts its durability and longevity. Here are essential guidelines to follow while storing merino wool:

  • Always store merino wool clean and dry. Dirty or moist wool is a breeding ground for bacteria, which can damage and weaken wool fibers.
  • Fold your wool neatly and store it in a cool, dry and well-ventilated place. Avoid direct sunlight and high humidity as it can cause discoloration, fade, and damage.
  • Consider using acid-free tissue paper as a barrier layer between wool layers, preventing fiber friction that can cause pilling and shedding.
  • Never store wool in plastic bags, as plastic traps moisture and promotes mold growth.
  • Make sure to air out and refresh your wool garments between each wear to maintain freshness.

Tips For Keeping Merino Wool Fresh And Soft

Keeping your merino wool fresh and soft is vital for maintaining its quality and durability. Below are some tips for ensuring this:

  • Use wool-specific detergents as regular detergents can damage wool fibers. Follow the instructions on the detergent label when washing.
  • Avoid using fabric softeners and bleach, as they can damage wool fibers and cause discoloration.
  • Avoid using hot water, which can shrink wool. Instead, opt for cold water and adjust your washing machine settings accordingly.
  • Don’t be afraid to gently steam iron your wool garments to remove wrinkles and restore their shape.
  • Store lavender sachets or cedar blocks in your wool storage to keep moths and other insects at bay.

By following these guidelines, your merino wool will remain fresh, soft, and long-lasting.
