But first the good news
Virgin wool is easy to clean because it has natural properties that distinguish it from other materials:
Virgin wool contains natural fibers that form a water-repellent outer layer. This means that stains and dirt particles are less absorbed into the fibers. Smaller dirt can often simply be brushed off.
Due to the natural structure of new wool, dirt is not absorbed so easily. The surface of the wool fibers is covered with tiny scales that can repel dirt particles and prevent stains from penetrating.
Virgin wool has the ability to absorb and neutralize odors.
