Nikwax Loft Down Wash 300ML.
Dirt and body oils will contaminate the down causing it to clump together and loose loft. Dirt also attracts water and reduces the beading-up of droplets on the fabric's surface. Wash the garment in Nikwax Down Wash non-detergent soap. Detegents can leave water-attractive residues that will not rinse out. They also contain agents that can wash away the natural oils of the down. Never use liquid detergents or fabric softeners. Please note this product cannot be shipped overseas.
