I use The Washsafe™, which i bought online from The Wool Company UK. http://www.thewoolcompany.co.uk/ . You don't even need to add any detergent, but if you want to get all the benefits from using one of our detergents, this also works very well.
Natural Sheepskin Throws and Rugs are very easy to care for and when washed they can look like new again
