Blankets made of wool possess many attractive qualities such as fire, water and wrinkle resistance as well as superior insulation. When caring for a woolen blanket, you should always defer to the washing instructions the product includes. Some manufacturers recommend that you dry-clean products. Yet, some wool is fine to wash in the washing machine.
Fill your washing machine with cool to lukewarm water, turn it off, and add the recommended amount of gentle soap to the water, such as a wool wash or castille soap. Avoid using commercial laundry detergents with additives and fragrances.
Place your woolen blanket into the washing machine, and push it into the water. Allow the blanket to soak for approximately 10-15 minutes with the washing machine off.
Use your hands to agitate the blanket in the water. Select the "Spin" cycle on your washing machine and allow it to spin the wool blanket.
Take the blanket out of the washing machine and place it aside for a moment. Re-fill the washing machine with cool to lukewarm water and stop it.
Place the blanket in the water and allow to soak for 10-15 minutes before selecting the "Spin" cycle. Allow the spin cycle to finish, and remove the blanket from the washing machine and spread it out on a flat surface to dry. If you have a drying rack large enough to accommodate the blanket, use it.
