"There is a very specific panic that sets in when you spill coffee on a beloved, expensive wool blanket. Wool is a miracle fiber—it's warm, breathable, and naturally repels dirt. But it has one fatal flaw: it hates heat and agitation. Throw it in a normal wash cycle, and you will pull out something the size of a placemat. I learned this the hard way with a gorgeous vintage Pendleton that I shrunk beyond recognition. But here is the good news: you do not have to dry clean everything. You can wash a wool blanket at home, and it's actually incredibly simple once you know the rules. We are going to treat the fiber with respect, use the right temperature, and skip the dryer entirely. Let's save your blanket."

Step-by-Step Instructions

Shake it out and spot clean first

Wool is naturally self-cleaning. The lanolin in the fibers repels dirt and water, meaning you shouldn't be washing a wool blanket very often at all. Most of the time, all it really needs is a good shake outside and some fresh air. If there is a specific stain, don't wash the whole blanket. Spot clean it. Mix a tiny drop of mild wool detergent with cool water. Dab the stain with a clean white cloth. Do not rub! Rubbing agitates the wool and causes it to felt and pill. Just press the damp cloth into the stain until it lifts.

PRO TIP:Hanging a wool blanket outside on a breezy, dry day will remove almost all musty odors without any washing required.

Prepare a cool, soapy bath

If the blanket truly needs a full wash, you are going to use the bathtub. Fill your tub with cool water. Never use warm or hot water—heat is the enemy of wool. Add a generous squirt of a specialized wool wash (like Eucalan or Soak). These detergents are formulated to clean without stripping the natural oils from the fiber. Swish the water around with your hand to mix the soap before you put the blanket in. You want a nice, gentle, soapy pool ready to go.

Submerge and soak—do not agitate

Gently press the blanket down into the water until it is completely submerged. Now, here is the most important rule: do not wring, twist, or scrub it. Imagine you are washing a delicate pastry. You are just letting the soapy water do the work. Press it down gently a few times so the water flows through the fibers, and then walk away. Leave it to soak for about 15 to 20 minutes. The dirt will naturally release into the water without any aggressive scrubbing.

The 3 Nevers of Washing Wool: 1. Never use hot water 2. Never wring or twist 3. Never use standard laundry detergent

Rinse out the soap

Drain the soapy, dirty water from the tub. Push the blanket against the side of the tub to squeeze out the excess water gently. Do not wring it out like a towel! Refill the tub with clean, cool water. Press the blanket down into the clean water to rinse it. You might need to drain and repeat this process once or twice until the water runs clear and there are no soap bubbles left. (If you used a no-rinse wool wash, you can skip this step entirely, which is why they are highly recommended.)

Dry it flat and reshape

Never hang a wet wool blanket over a clothesline or a single rod—the weight of the water will stretch the fibers and completely warp its shape. And absolutely never put it in the dryer. Instead, lay it out flat on a clean surface out of direct sunlight. A mesh drying rack is perfect, but a clean bed with some dry towels underneath works too. While it is damp, gently pull the edges to reshape it back to its original dimensions (this is called 'blocking'). Leave it alone until it is completely, 100% dry.
