Washing of natural wool
Our wool slippers and wool clothes can be washed in the washing machine using the program for wool if you have one (low temperature). Do not spin or dry in the washing dryer.
However, in our opinion it is better to wash it by hand in 30 degrees to be sure no washing machine will damage the products. Let it soak in warm water using wool washing detergents and let it dry flat.
