Your wool sweater deserve proper care to stay looking their best. Follow these steps to clean them safely without causing damage.
Use cool water only. Hot water causes wool to felt and shrink irreversibly. Add a small amount of wool wash or mild detergent.
Gently press the sweater into the water and let it soak for 10-15 minutes. Do not agitate, wring, or rub the fabric.
Lift the sweater out supporting its full weight (do not let it stretch). Gently press water out -- never wring or twist.
Lay the sweater flat on a dry towel, roll the towel up with the sweater inside, and press to absorb excess water.
Unroll and lay the sweater flat on a clean dry surface or drying rack. Reshape it to its original dimensions. Flip after 12 hours.
