All of our hides are Eco-tanned with the environment in mind, that means there is no chrome or bleaches used in the tanning process. The lanolin in the wool helps make the sheepskin naturally dirt and bacteria resistant. In most cases a light brush, a good shake and an airing is all they need to keep them looking good. For cleaning we recommend spot cleaning the wool side only using a sheepskin shampoo (avoid wetting the leather). For heavy soiling or stains we recommend you speak to a specialist cleaner.
