Look for Wash Permission Before Putting a Wool Blanket in a Machine

Woolmark recommends following the blanket's care instructions before washing a heavily soiled wool blanket. Its machine-washing directions are conditional on the label permitting that method, then call for an appropriate gentle wool cycle, cold water and a specified wool detergent. The word wool alone does not establish permission.

The same guide discusses airing and gentle brushing as ways to refresh a blanket between washes. For a liquid stain, it describes blotting rather than scrubbing. Read those methods as parts of a care routine matched to the blanket, with the washing and drying instructions considered together rather than inferred from an ordinary bedding cycle.
