Modal can be used alone or mixed with other fibers, so Ariel starts its care guidance with the garment's label. If machine washing is allowed, the reference recommends a cold-water cycle. That qualification matters because a soft modal-containing garment may also include fibers or details with their own care requirements.

The guide describes air drying or a cool tumble-dryer cycle, subject to the item's instructions. When ironing is suitable, a pressing cloth provides a barrier between the iron and the fabric. Read the washing, drying and finishing directions together rather than assuming the material's soft feel determines an unrestricted laundry method.
