Is Washing Merino Wool Always Necessary?

Before we explain how to wash merino wool, it is good to know that woollen items do not get dirty quickly. One of the special qualities of merino wool is that it is naturally dirt-repellent and absorbs odours less easily. This means washing merino wool is not always necessary. For everyday merino wool care, it is often enough to air your woollen blanket, throw or garment regularly. Hang the item outside or in a well-ventilated room and it will feel fresh again in no time.

How To Wash Merino Wool: Choose The Right Method

If you do decide that your merino wool needs washing, it is important to check what the care label advises. There are generally two options:

Professional Cleaning

If the care label shows a circle with the letter P, often with a line underneath, professional dry cleaning is the right choice. The P indicates that the item can be cleaned using perchloroethylene, while the line underneath means a low temperature and the addition of water are required. Always inform the dry cleaner clearly about these instructions, as proper professional merino wool care can significantly extend the life of the item.

Washing Merino Wool Yourself

Do you see a hand symbol on the care label? Then you can consider washing your merino wool item yourself. How to wash merino wool at home? Follow these steps:

Use lukewarm water (maximum 30°C).
Choose the right merino wool detergent (without enzymes or bleach).
Wash the item gently by hand, without rubbing or wringing.
Rinse thoroughly using water at the same temperature.
Gently press out excess water, without twisting.

For some merino wool items, machine washing is possible, but only under specific conditions. Always choose the wool or hand-wash programme, with a temperature of no more than 30°C. Use a special merino wool detergent that does not damage the natural lanolin in the wool. Only use the washing machine if this is clearly stated on the care label.

Spinning And Drying Merino Wool

After washing, the next question is whether you can spin merino wool. The short answer: preferably not, or only very gently. If you do choose to spin the item in the washing machine, use a very low speed and a short cycle. A better option is to roll the item in a towel and gently press out the excess water.

When drying merino wool, never use a tumble dryer and avoid direct sunlight or heat sources. Lay the item flat on a towel to dry, keeping it in its original shape. Do not pull it into shape while it is wet, as this can cause stretching or distortion. High-speed spinning or incorrect drying are the two main causes of shrinkage and deformation in merino wool.

Choosing The Right Merino Wool Detergent

An essential part of successfully washing merino wool is choosing the right detergent. Regular detergents often contain enzymes and bleaching agents that can damage wool fibres. A special merino wool detergent is pH-neutral and helps preserve the natural qualities of the wool.

There are various merino wool detergents available that are specifically developed for wool. These often contain lanolin, which keeps the wool soft and flexible. This is especially important when washing merino wool in the washing machine.
