What is wool detergent and why is it different?
Wool detergent is specially formulated for animal protein fibers (wool, cashmere, mohair, silk). It cleans gently and helps protect the fiber structure.
- Without enzymes: enzymes break down proteins – you want to avoid that with wool.
- pH neutral or slightly acidic: supports the natural balance of wool and helps maintain a soft hand.
- Lanolin-friendly & caring: many wool detergents respect (or add a little) lanolin, so that fibres remain supple.
- Subtle scent or fragrance-free: pleasant for items worn close to the skin.
Why is this important? Wool has microscopic scales that can snag (felt) or shrink if handled improperly. Gentle, enzyme-free, and pH-balanced washing helps prevent this.
When do you use wool detergent?
Always use with real wool textiles: sweaters, cardigans, scarves, hats, blankets. Also suitable for cashmere, alpaca, mohair, and angora. Some delicate detergents are also suitable for wool (check the label: "for wool/silk" and "enzyme-free").
Tip: Wash wool as little as possible. Airing is often enough to remove odors. Is a wash necessary? Choose a wool cycle (usually 30°C, low spin) or hand wash in lukewarm water.
How to wash wool properly?
Basic steps with wool detergent
- Read the label: does it say "hand wash only"? Follow that. Machine washable? Choose the wool or delicates cycle.
- Correct dosage: wool needs little soap; too much makes rinsing difficult.
- Temperature: 20–30°C is ideal. Avoid temperature shock (do not wash hot and rinse ice cold).
- Machine wash: Use a laundry net and a low spin cycle. Wool programs often have this setting already set correctly.
- Hand wash: first dissolve the product, gently agitate the textile (do not wring/scrub), soak for a maximum of 5–10 minutes and rinse with water of the same temperature.
- Drying: Never wring. Squeeze out the water, wrap in a towel, and dry flat, keeping it in shape. Do not tumble dry.
