Positive aspects first. Fortunately, Merino wool is easy to look after. Consequently, you do not have to worry that you won’t be able to wash your jumper or that you have to handle it in a special way. Indeed, you can even pop it into the washing machine – which is not recommended for all natural fibres.
However, please note that Merino wool does not like fabric softener nor a tumble dryer. Then there is a danger that the wool will develop holes or shrink. As Merino wool remains odour-free for lengthy periods, there is no need to wash the item after wearing it.
Indeed, it is often enough to simply hang out your Merino woollen jumper or jacket in the open air instead of washing it.
