Meditation cushion - needs cleaning (Abbeville Village SW4)

Red yoga matters meditation cushion - buckwheat inside. Cover needs a really good wash - has some mould and marks from food getting on it when a toddler came to stay! Could be done by decanting the buckwheat and washing the cover or spot cleaning with a cloth. We just don't use it enough to make the effort. https://www.yogamatters.com/products/yogamatters-organic-cotton-zafu-medita...
