  1. Turn clothing inside out: Before washing, turn your Merino wool socks and apparel inside out to protect the outer surface of the fabric. Tip: Use a mesh bag if you have one to prevent snagging and twisting.
  2. Use a mild soap: Opt for a mild soap or one specifically designed for wool or delicate fabrics. This will ensure gentle cleansing without compromising the integrity of the Merino wool.
  3. Handwash or machine wash on delicate: When machine washing Merino wool, select the delicate or gentle cycle and use cool water. If handwashing, soak your Merino wool item in cool, soapy water for 3-5 minutes, gently agitate the clothing, then rinse. Note: Handwashing is always the safest method to preserve your Merino wool.
  4. Lay flat to dry: To keep your Merino wool products in top condition, you should lay them flat on a dry towel to dry. For some Merino wool items, you may be able to tumble-dry them in the dryer on the lowest heat setting, but be sure to check the care label first.

Dos and Don’ts of Washing Merino Wool

  • Check the care label on your Merino wool garments for any specific instructions to prevent any unintentional damage.
  • Don’t expose Merino wool to heat, as it can shrink or damage the material. Avoid hot water, drying with heat, direct sunlight, and ironing.
  • Never use bleach or fabric softener, as these products will damage and destroy Merino wool fibers.
  • Avoid laundry detergents with enzymes, as these will break down Merino wool over time. Look for a mild soap with a neutral pH.
  • Don’t overwash your Merino wool. Naturally odor-resistant, you won’t necessarily need to wash it after every wear. It’s time to wash if you haven’t done so in a while, your clothing is stained, or it has been heavily sweated in.
