To begin with, a wool garment is largely self-cleaning and relatively dirt-repellent. This means that you do not have to wash it as often, but it may be enough to air the garment from time to time. Why, you may be wondering? To explain it all, we need to go down to the microscopic fibre level and study what a wool fibre looks like. Unlike many other materials, the wool fibre has a scale-like structure which means that the fibres easily hook together and that dirt is more easily transported out to the surface of the garment.

The surface layers of the fibres, which are covered by the fat: lanolin, a fat that is naturally produced by the sheep, also helps to make the garments moisture and dirt repellent.

When the wool fibres are covered with the fat lanolin, you should avoid washing with grease-dissolving detergent, as these can destroy the garment's natural self-cleaning properties. Instead, we recommend using a detergent intended for wool.

Wash seldom

It's advisable to wash your wool garment sparingly. It may be sufficient to wash it once a year or when the sweater is dirty or has a bad odour.

Air your wool sweater

Often, airing your wool garment is enough to freshen it up. This saves water and prevents the fibres from wearing out.

Brush

If your sweater is only lightly dirty, use a clothing brush to remove the dirt. This helps avoid over-washing.

Spot treat

Treat any stains using a cloth, detergent, and lukewarm water. The wool-on-wool method can work for removing smaller stains. Gently rub a part of the fabric against the stain.

Dry the garment

- Avoid tumble drying. Heat can shrink and damage the fabric.

- Lay the sweater on a towel immediately after washing and gently press out excess water without wringing. Dry flat.

- Do not hang your knitted sweater to dry, as it may lose its shape.

Steam if necessary

If your garment is very wrinkled, you can gently steam it, although it is usually unnecessary.

Fold and store

Think sustainably

- If your wool garment pills, you can use a wool comb or a fabric shaver.
