Start with construction, not just the item name

Cashmere sweaters are delicate knitwear that can felt, shrink or stretch. The label determines whether hand washing, gentle machine washing or professional cleaning is appropriate, and flat drying is often the safer shape-preserving option.

Choose the washing method

Confirm whether the sweater is hand-washable, machine-washable or dry-clean-only before wet cleaning. Fine animal fibers and garment construction are sensitive.

Control the main risk

When washing is allowed, use mild detergent, cool/lukewarm water and minimal agitation. Agitation and heat can felt animal fibers.

Dry without undoing the wash

Dry flat away from strong direct heat unless the label states another safe method. Shape and fiber are heat-sensitive.

When to stop and follow the manufacturer

If the item has electronics, specialty coatings, dry-clean-only instructions, non-removable structure or a conflicting care label, do not force a generic home-laundry method. The product or finished-item instructions take priority.

Care label first

Item construction, filling, coatings, electrical components and trim can change the safe method. Follow the finished-item care label and manufacturer instructions when they are more specific.
