This is an excellent product for washing fleeces and other fibres and can also be used on delicate fabrics. Only a small amount is needed to wash an average size fleece : 1 TBSP mixed into 2 gallons of hot water. Add 1lb of raw fleece. Soak for 20 minutes and rinse. The product is low foaming making rinsing far easier.
