How to Wash and Care for Wool Sweaters Without Shrinking Them
By Admin · 2026-10-13
A good wool sweater is an investment, and it is easy to ruin in the wash. The good news is that wool needs less washing than you think, and looking after it properly is simple.
Check the care label first
Always read the label. Some wool garments are labeled "dry clean only", and some are machine washable. If you are unsure, do a gentle hand wash or consult a professional cleaner.
How often to wash
Wool naturally resists odors and does not need to be washed after every wear. Air it out for a day or hang it in a steamy bathroom to refresh it. Wash it only when it looks dirty or smells. For most people this is after several wears.
How to hand wash wool
1. Fill a basin or sink with cool or lukewarm water.
2. Add a small amount of wool-safe detergent or gentle shampoo.
3. Turn the sweater inside out and place it in the water. Press it gently under the surface.
4. Soak for 10 to 15 minutes. Do not scrub, twist or rub, because friction causes felting.
5. Drain the water and rinse with water of the same temperature until the suds are gone.
Removing the water
- Do not wring. Gently press the water out.
- Lay the sweater flat on a thick, clean towel, roll the towel up with the sweater inside, and press to absorb moisture.
Drying
- Reshape the sweater on a dry towel or a mesh drying rack, flat.
- Keep it out of direct sunlight and away from heaters.
- Never hang a wet sweater, as the weight will stretch it.
- Never put wool in a hot dryer.
Machine washing, if the label allows
- Use the wool or delicate cycle with cold water.
- Place the sweater in a mesh laundry bag.
- Use a low spin speed and a wool-friendly detergent.
- Do not wash it with heavy items such as jeans or towels.
Dealing with pilling
Small balls of fiber, called pills, are normal, especially under the arms and on sleeves. Remove them with a fabric shaver or a wool comb. Pull gently, and do not tug at them with your fingers.
Removing stains
Treat stains quickly by blotting, not rubbing, with a damp cloth. For tough stains, use a small amount of wool-safe stain remover and test it on a hidden area first.
Storing wool
- Fold your sweaters rather than hanging them, to avoid stretching.
- Store them in a breathable cotton bag or drawer.
- Keep them clean before storing them for the season, since moths are attracted to dirt and sweat.
- Use cedar blocks or lavender sachets to discourage moths.
If your sweater has shrunk
Soak it in lukewarm water with a little hair conditioner for 10 minutes, press out the water and gently stretch it back into shape while it dries flat. This does not always work, but it can help with mild shrinkage.
A little care goes a long way. Wash less, treat gently, dry flat, and your wool sweaters will keep their shape and softness for many winters.
