How to Wash Merino Wool?

Properly washing and caring for your merino wool clothing is essential to ensure it performs at its best for many years. While merino wool is renowned for its natural odour resistance, it's crucial to wash your base layers regularly. This article will walk you through the steps to ensure your merino garments remain clean and fresh after every wash. Let's dive into the essentials of washing merino wool clothing.

Can You Wash Merino Wool Clothing?

Yes, you can and should wash merino wool clothing. Many people avoid washing merino garments out of fear of shrinking. However, water alone doesn't cause wool to shrink. The real culprits are excessive heat and friction during the washing process. This guide will teach you how to avoid these pitfalls.

How Often Should You Wash Merino Clothing?

Thanks to merino wool's natural properties, you don't need to wash it as frequently as synthetic fibres. This reduced washing frequency not only conserves water but is also environmentally friendly. With merino wool, you can comfortably get 3-4 days of use from a base layer before it needs washing. However, items like socks and underwear may require more frequent washing. Still, you might be surprised at how long you can wear your merino wool garments before they need a cleanse.

How to Wash Merino Clothing

Hand Wash: The safest method for washing merino wool is by hand. Ensure your basin is clean and soak your garment for 10-20 minutes in lukewarm water with a mild detergent. After soaking, rinse thoroughly with clean water. Remember not to wring your clothing as this can distort its shape.

Machine Wash: If you prefer machine washing, set your machine to a delicate cycle and ensure the water temperature doesn't exceed 30˚C. Use a liquid detergent like Ecover, Delicate, or Nikwax Woolwash. Always turn your garments inside out and avoid using powder detergents, as they can wear out your clothing and leave residue. After washing, either dry your merino wool flat or hang it in a place away from direct sunlight.

Merino Wool Washing FAQs

  • Can I tumble dry merino wool? - It's best to avoid tumble drying as the high heat can shrink or misshape your garment.
  • Is it okay to use fabric conditioner on merino wool? - No. Fabric softeners can inhibit the natural properties of merino wool, making it less effective at moisture-wicking and odour resistance.
  • What detergent is best for merino wool? - A gentle liquid detergent is recommended. Avoid powder-based detergents as they can cause wear and leave residue on your garments.
