Myths and truths about washing wool
“Wash infrequent, air often”
True! One of the great perks with wool is that wool garments stay fresh without washing longer than garments made of cotton or synthetics. This means fewer washes throughout the garment’s lifecycle, a considerably lower impact on the environment than other types of fabrics. The longer away from the skin a garment is used, the more infrequent it can be washed. Merino wool long johns might need to be washed after a few days, but cashmere wool sweaters don’t need to be washed more often than a few times per year. Woolen coats and jackets even more infrequent.
Air your wool garments by letting them hang outside over the night, preferably in moist conditions. When a stale smell doesn’t disappear after the garment has spent a night hanging outside, or it’s become dirty, then the time is right for washing.
“Wool garments stain easily”
True! Wool garments don’t easily become dirty. They do, however, stain pretty easily. Raw and ecological wool are amongst those the wool fabrics who are most resistant to stains, but many other kinds of wool are vulnerable for things that’s easily spilled; berries, jam, coffee or chocolate smoothie. Stains also easily become permanent, compared to synthetic garment who also stain easily but where the risk for permanent stains are lower. The advice is to spot treat the stain as soon as it appears. Waiting until the stain has dried to treat it increases the risk of it becoming permanent.
