Airing does wonders for wool. Spot clean as required or gentle handwash in lukewarm water, press in a towel to remove moisture and dry flat.
Wool has high self-cleaning powers. Dirt has a hard time sticking to the wool fibre because every single fibre is encased in the wool fat lanolin. The same is true of odours. A short airing is enough and unpleasant scents are soon gone.
Note on using machine wash!
Wool washing programmes of washing machines vary massively, therefore we can not grant warranty for any damages. With regards to using your wool washing machine cycle, always use cold. If you choose to wash at 30 degrees the machine will still rinse with cold water and this shock to the fibres can cause the wool to shrink.
