You can enjoy your wool product for years if you maintain it properly. You don't have to wash wool very often, it is naturally anti-bacterial. A good night of hanging out also ensures that odors often disappear. Still, it's a good idea to wash occasionally.

Hand wash

As a rule, it is recommended to wash wool by hand. But this certainly also has risks. Wool must be washed at 30 degrees, and that feels quite cold. But few people check the water with a thermometer. Washing too hot results in shrinkage, but too cold can also cause wool to shrink. People often use too much detergent when washing by hand, which makes it harder for them to rinse it out. Wringing too hard is also a risk.

Correct temperature

As stated above: you wash wool at 30 degrees, and certainly not hotter. But also not colder! The fibers can be damaged if the temperature is too cold to startle and this is also possible shrinkage to assure. 

In the machine

It is safest to wash wool in the machine, on the wool wash program. Make sure the centrifuge is not set higher than 600 rpm. Here again: a high speed causes your woolen clothing to shrink. Also important: wash wool with wool. Do not include jeans or clothing with zippers. 

Wool detergent

Wool naturally contains a type of fat, lanolin. This gives the wool a soft protective layer against dirt and retains heat for a long time when it is cold. But it also ensures that the wool remains elastic and wears less quickly. By using a special wool detergent that contains lanolin, you can continue to enjoy these properties. In addition, special wool detergents never contain bleach, which is disastrous for wool.
