If your Woolmark-approved garment’s care claim says that you can machine wash your piece of wool clothing, then it means it can safely be machine washed in a washing machine multiple times, without shrinkage taking place.
Ideally garments carrying such labels should be washed on the wool setting (usually gentle action at 40°C). If your washing machine does not have a wool cycle, then it is recommended to use the cold water wash or wash cycle for delicates.
It is recommended that garments are flat dried after washing.
You may even notice that your washing machine or tumble dryer has the Woolmark Apparel Care symbol on it, which means that your machine has passed rigorous and independent testing and has been approved by The Woolmark Company.
For hand or machine washing wool garments, use only a neutral, mild detergent that is preferably Woolmark recommended (look for the Woolmark symbol on the packet). Find Woolmark-approved products in your country.
The Woolmark Company has released a Wool Care Guide app, placing information on apparel care at the tip of your fingers. Available for all Apple and android devices, the Wool Care Guide app can be downloaded free-of-charge via the Apple App Store or Google Play Store.
