The Essential Wool Care Guide: Washing, Drying, and Storage
Wool is durable and forgiving—but only if you treat it right. Here's exactly how to clean, dry, and store your pieces so they last.
5 min read · IrisWool is one of fashion's most resilient fibers—it resists wrinkles, regulates temperature, and actually repels dirt. But many people treat it like delicate lingerie, when really it just needs a different approach than cotton or synthetics. The key is understanding that wool fibers respond to agitation and heat, not to water itself.
Whether you're caring for a £40 high-street cardigan or a £400 investment coat, the method stays the same. Follow this guide and your wool will soften with age instead of pilling, shrinking, or losing shape.
Wool actually resists dirt—you often don't need to wash it as frequently as you think.
What you'll need.
- 01Wool-specific detergent or baby shampoo
- 02Basin or sink
- 03Cool water
- 04White vinegar (optional)
- 05Clean white towels
- 06Breathable cotton storage bag
- 07Cedar blocks or lavender sachets
Step one · 3 minutes
Check the label and spot-test first
Read the care tag. Most wool can be hand-washed, but some requires dry cleaning. If the label says hand-wash, test your detergent on a hidden seam by applying a drop of diluted soap to the inside of the garment and rinsing. Wait 10 minutes. If the color doesn't bleed or the fiber doesn't feel stiff, you're safe to proceed. This one step prevents disasters.
Superwash wool (treated to be machine-washable) still benefits from hand-washing to extend its life.
Step two · 2 minutes
Prepare your wash basin
Fill a sink or basin with cool water—never hot, which causes shrinkage. Add a teaspoon of wool-specific detergent or baby shampoo. Stir gently to dissolve. The water should feel barely soapy; too much detergent leaves residue and makes rinsing harder. Avoid regular laundry detergent, which is too harsh and breaks down wool fibers over time.
Woolite and similar products work, but plain baby shampoo is cheaper and equally effective.
Step three · 5 minutes
Soak and gently agitate
Submerge the garment fully and let it soak for 5–10 minutes. Don't scrub or wring. Instead, gently squeeze the soapy water through the fibers by pressing the garment against the basin floor. Pay attention to underarms, necklines, and cuffs—these areas absorb body oils and need gentle pressure. After soaking, drain the soapy water without lifting the garment (which stretches it when wet).
If the garment is visibly soiled, soak for the full 10 minutes. For light refresh, 5 minutes is enough.
Step four · 5 minutes
Rinse thoroughly in cool water
Drain the basin and refill with fresh cool water. Gently press the garment to release soap, squeezing the clean water through the fibers. Repeat this process 2–3 times until the water runs clear and you feel no soap residue. This is tedious but essential—leftover detergent makes wool stiff and dull. On the final rinse, add a splash of white vinegar (one tablespoon per basin) to restore softness and close the cuticles.
If you're in a hard-water area, use distilled water for the final rinse.
Step five · 2 minutes
Remove excess water without wringing
Lift the garment gently and support it fully with both hands. Squeeze gently—don't twist or wring, which distorts the shape. Place it on a clean, dry towel laid flat. Roll the towel tightly around the garment to absorb water, pressing gently as you roll. Unroll and transfer the garment to a fresh dry towel, still laid flat.
Use white towels to avoid dye transfer onto light-colored wool.
Step six · 15 minutes
Dry flat and store properly
Lay the garment flat on a dry towel in a well-ventilated area, away from direct sunlight and heat sources. Reshape it gently to its original dimensions—smooth the sleeves, adjust the neckline, and even out the hem. Let it air-dry completely (usually 12–24 hours). Once dry, fold it loosely and store in a breathable cotton bag or drawer. Avoid wire hangers, which create shoulder dimples. Cedar blocks or lavender sachets deter moths naturally.
Never hang wool sweaters or knits—gravity stretches them out of shape. Fold everything.
How to know it worked
Your wool should feel soft and smell fresh, with no soap residue or stiffness. The garment returns to its original shape and size. There should be no pilling, color fading, or water stains. If stored correctly, it's ready to wear immediately or fold away until next season.
Questions at the mirror.
Can I machine-wash wool?
Only if the label explicitly says machine-washable or superwash. Use the wool cycle with cold water and wool detergent. Hand-washing is always safer and extends garment life.
My wool sweater has pilling. Is it ruined?
No. Pilling is normal and doesn't mean the wool is low-quality—it's friction between fibers. Use a fabric comb or pill remover to gently brush away bobbles. Avoid over-washing, which increases pilling.
How often should I actually wash wool?
Much less than you think. Wool resists odor and dirt. Spot-clean stains, air it out between wears, and wash every 4–6 wears or when visibly soiled. A sweater worn once a week needs washing roughly monthly.
What if my wool shrunk?
Gently soak it in cool water with a capful of hair conditioner or glycerin for 15 minutes. Carefully stretch it back to shape while damp and lay flat to dry. This works best for minor shrinkage.
Is dry cleaning necessary for wool coats?
Not always. Brush off surface dirt regularly and air the coat outside. Dry clean only when needed (usually once per season). Over-dry-cleaning weakens fibers and is expensive.
