FAQs
Can I machine wash a wool sweater?
Only if the label allows it. Use wool cycle, cool water, wool detergent, and a mesh bag.
Can wool sweaters go in the dryer?
Usually no. Heat and tumbling can shrink wool. Dry flat.
How often should I wash wool?
Wool often needs airing more than washing. Wash when dirty or odor remains after airing.
