Yes, but only if the sewn care label clearly says the blanket is machine washable. If it does not, hand wash or use a professional cleaner to avoid shrinkage or felting (Woolmark).

When machine washing is allowed

Wool blankets are finished and constructed in different ways, so the care label is the deciding instruction. Only machine wash if the label permits it and then follow the wool-specific settings it recommends (Woolmark).

How to machine-wash a wool blanket safely

If the label allows machine washing:

Select a wool or delicate cycle and cold water (Woolmark).
Use a wool wash detergent only (Woolmark).
Set spin to off if possible; many wool guides advise no spin for blankets (Luvian Woollens) (The British Blanket Company).
Wash the blanket on its own, or place it in a large mesh laundry bag for extra protection from friction (Prince of Scots).
Remove promptly when the cycle ends to prevent misshaping (The British Blanket Company).

Before you press Start: machine-wash checklist

Confirm the sewn label says machine washable
Select wool or delicate cycle with cold water
Add a wool wash detergent (follow the detergent dosing)
Set spin to Off (or choose hand wash if your washer cannot disable spin)
Wash the blanket alone or inside a large mesh laundry bag

Hand washing: when and how

Choose hand washing if the label forbids machine washing or if your washer cannot run a cold wool cycle without spinning. Fill a tub with cold or up to 30°C water, add a wool detergent, soak about 10 minutes, gently move water through the fibers without rubbing, then rinse. Do not wring; roll the blanket in a towel to remove excess water (Luvian Woollens).

Drying and reshaping

Lay the blanket flat to dry and reshape it while damp. Support its weight so it does not stretch (Woolmark) (The British Blanket Company).
Avoid direct sunlight, which can fade color and make wool feel coarse if it dries too quickly (Woolmark).
Do not tumble dry. Woolmark guidance advises against dryers for blankets to protect softness and shape (Woolmark).
To speed drying without stretching, drape the blanket across two parallel lines or racks and rotate occasionally (Luvian Woollens) (The British Blanket Company).

Common mistakes and quick fixes

Heat and agitation cause shrinkage and felting. Always use cold water and gentle handling (Prince of Scots).
Do not spin or wring. Skip spin and press water out gently, then roll in a towel (Luvian Woollens) (The British Blanket Company).
Avoid fabric softener, which can leave residue that worsens pilling on wool (The British Blanket Company).
If the blanket looks slightly misshapen after washing, reshape it gently while damp and dry it flat (The British Blanket Company).

Post-wash drying checklist

Press out water, then roll the blanket in a clean towel
Lay flat on a rack and reshape corners and edges while damp
Keep away from direct heat and sunlight, turning occasionally for even drying

Frequently asked questions

Do I need a special detergent for wool?

Yes. Use a wool wash detergent as recommended in wool care guidance (Woolmark).

Can I use fabric softener on a wool blanket?

It is best to avoid fabric softener on wool blankets because residues can exacerbate pilling (The British Blanket Company).

What if my washer cannot disable spin?

Hand wash instead to avoid mechanical stress, as many wool blanket guides advise no spin for best results (Luvian Woollens) (The British Blanket Company).
