Merino wool is one of the most popular natural materials for clothing – especially among outdoor enthusiasts, travelers, and people who value comfort and sustainability. It is soft, temperature-regulating, odour-neutral, and pleasant on the skin. However, to ensure Merino clothing retains its special qualities for a long time, proper care is essential. Anyone who wants to wash Merino wool should know some important rules to avoid shrinking, felting, or loss of shape.

Why Merino wool needs special care

Merino wool differs significantly from regular wool. The fine fibres come from the Merino sheep and are much thinner and more elastic. This very structure makes Merino wool so comfortable – but also sensitive to heat, friction, and the wrong detergents. With the right care, Merino wool remains shape-stable and functional for many years.

Do you have to wash Merino wool after every wear?

No – and that is one of the great advantages of Merino wool. Thanks to its natural antibacterial properties, it hardly absorbs odours. Often, it is enough to air the garment well after wearing. Especially with outdoor or sportswear, you can often save yourself frequent washing. Fewer washes not only mean longer durability but also more sustainability.

Washing Merino wool: hand wash or washing machine?

Both options are basically possible – the key is the correct procedure.

Hand wash
The gentlest method is hand washing. Use lukewarm water (maximum 30 °C) and a special wool or delicate detergent. Gently move the garment in the water, do not rub or wring. Then rinse with clear water.

Washing machine
Modern washing machines usually offer a wool or delicate programme. Here too: maximum 30 °C, low spin speed (600 rpm or less), and no fabric softener. Make sure to wash similar colours together and place delicate items in a laundry bag.

The right detergent for Merino wool

Regular all-purpose detergents are unsuitable for Merino wool because they contain enzymes that can attack the wool fibres. Instead, use a special wool detergent or delicate detergent without bleach and without fabric softener. Fabric softener coats the fibres and impairs the natural properties of Merino wool, such as breathability and moisture regulation.

Common mistakes when washing Merino wool

Many damages to Merino clothing arise from small care mistakes. You should definitely avoid these:

• Water that is too hot

• Strong spinning

• Rubbing or wringing

• Using a tumble dryer

• Fabric softener or harsh detergents

Even one of these points can cause Merino wool to shrink or felt.

How to dry Merino wool properly

After washing, Merino wool should never be hung up, as it can distort under its own weight. Instead, gently roll the garment in a towel to absorb excess water. Then lay it flat on a towel and let it dry in the air. Direct sunlight or heaters should also be avoided, as they can dry out the fibres.

How to keep Merino wool looking good for a long time

Besides proper washing, storage also plays an important role. Merino clothing should be stored clean and dry, preferably folded in the cupboard. Moths like natural fibres – lavender sachets or cedarwood help keep them away naturally.

With frequent wear, small pills can form over time. These can be gently removed with a lint shaver or by hand without affecting the quality of the Merino wool.

Sustainability through proper care

Merino wool is a long-lasting natural product – provided it is cared for properly. Washing consciously, using less water, and avoiding harsh chemicals not only extend the life of your clothing but also contribute to environmental protection. Especially with high-quality Merino wool, careful care pays off doubly.

Conclusion: With the right care, Merino wool remains a favourite for years

Washing Merino wool is easier than many think – if you follow a few basic rules. Gentle temperatures, the right detergent, and careful drying are the keys to keeping Merino wool durable, soft, and functional. Those who care properly for their Merino clothing will enjoy its comfort, versatility, and natural quality for a long time. High-quality Merino wool, such as that offered by Alpinloacker, clearly shows how much careful care pays off in the long run.
