Immerse clean item(s) in warm water and agitate to mix, ensuring complete wetting.

Sleeping bags:

Agitate to mix, leave to soak for 5-10 minutes, then agitate thoroughly.
Rinse in cold water until water runs clear. Repeat process, drain and gently press bag to expel excess water.
If care label allows, tumble dry according to manufacturer’s instructions on a low setting until ‘clumps’ have disappeared. Teasing apart clumps repeatedly during drying process will help restore loft to the down.
To maintain waterproofing always wash with Nikwax Down Wash Direct®. Do not use detergents.
Make sure to thoroughly dry your down filled gear…
To get the maximum amount of water out of your down it’s best to spin dry multiple times, each time incrementally increasing the speed of the spin cycle. Wet down is heavy, so if items are spun too quickly while still holding a large amount of water it is possible that internal baffles may be broken.
Nikwax Down Proof treated items need no heat to develop water repellency. However, tumble drying is recommended (if care label allows) to ensure that the down is dried thoroughly and as quickly as possible. Leaving down wet or damp can ruin it completely. Tumble dry according to manufacturer’s instructions on a low setting until clumps have disappeared. Ensure that there is sufficient room in the tumble drier to house the item once dry, as items will return to their original size during the drying process.
Teasing apart clumps repeatedly during drying process will help restore loft to the down.
After tumble drying it is recommended to air item(s) for at least a day in a warm and dry space, prior to packing away.
