It is important to know that natural fibres are especially sensitive towards high temperatures and any changes in water temperature. If your washing machine has a gentle wool cycle, you can wash the socks inside out for best results, or gently by handwash. Please wash seperateley and only use a  Wool detergent. Please do not tumbledry or dryclean the socks.

The upside is that you have a natural product and often you do not have to wash them so often as a normal sock, you can even go 5 days or more without having to wash them!
