Down Wash™

The easy to use, safe, high performance cleaner for down filled clothing and gear.

The safe way to thoroughly clean and revitalize insulation, water repellency and breathability.

Why down items lose their insulating properties when they get dirty...

Down filled items are used to provide lightweight insulation to keep you warm. The structure of down allows air to be trapped between its filaments and warmed by body heat to provide insulation for the user.

Through use, dirt and body oils build up on down items. This affects both the fabric and the down fill. Dirt attracts water; if the fabric absorbs water, rain and condensation can easily transfer into the down. If down gets wet it clumps together. This causes it to lose loft and insulation as it can’t trap air effectively. When wet, down loses all of its insulating properties, as water conducts heat away from the body up to 25 times faster than air. It will also gain weight and its breathability will be significantly reduced; leaving you feeling cold, wet and uncomfortable.

Down filled items are most likely to get sweaty and wet inside when used in damp or wet conditions. Therefore it is important to stop down filled gear from getting wet by maintaining Durable Water Repellency (DWR). The outer fabric of your down filled item, as well as the down inside, must be maintained to ensure comfort. Nikwax Down Wash™ will revitalize the insulation, DWR and breathability of your garment.

Down is ideal for very cold and dry conditions…

Down has exceptional insulating properties, trapping air between its filaments to keep you warm. No other product offers so much insulation for so little weight and bulk. It’s ideal for sleeping bags, jackets, vests, and down clothing in general.

Water, whether it is rain or condensation from sweat, compromises the insulating properties of down. If down gets wet it loses all of its insulating capacity and also causes weight gain. This reduces the comfort of the user, causing them to feel cold and wet, but more importantly the reduction in insulation is dangerous and in severe cases can lead to hypothermia. When wet, down loses all of its insulating properties, as water conducts heat away from the body up to 25 times faster than air.

Nikwax Down Wash™ revitalizes insulation and the Durable Water Repellency (DWR) of both the outer fabric and down fill. This prevents water absorption and maintains breathability, keeping you warm, dry and comfortable.

Down items are ideal for people who are outside in very cold conditions…

Anyone who is outside in very cold weather will benefit from down items. Whether you’re a mountaineer, skier or snowboarder or you’re regularly outside in cold conditions, you will benefit from the lightweight insulation of down.

Use Nikwax Down Wash™ when your down items soak up water…

Your down items could be soaking up water because the Durable Water Repellency (DWR) has been compromised by dirt, or because it has been cleaned with a conventional laundry detergent. Dirt attracts water and household detergents leave water attracting (hydrophilic) residues, leading to fabric and down 'wetting out' in wet or damp conditions.

If your down items are relatively new, or have been recently treated with Nikwax Down Proof™, then cleaning with Nikwax Down Wash™ will not only remove contaminants, such as dirt and residues left behind by household detergents, but also revitalize insulation, breathability and DWR.

However, once the gear has been thoroughly used, you will need to add DWR, using Nikwax Down Proof™, after cleaning first with Nikwax Down Wash™. This will add DWR to the outer fabric of the gear and also the down fill.

Down needs Nikwax Down Wash™; a specialist cleaner…

Conventional laundry detergents leave behind a water attractive (hydrophilic) residue on both the outer fabric and the down fill which masks Durable Water Repellency (DWR). This causes the fabric and down to absorb water and ‘wet out’ in damp or wet conditions, leading to loss of insulation.

Cleaning products that are not designed specifically for the treatment of down items may also compromise the loft properties of down. If you choose the wrong cleaner, you might cause the dirt from the outer fabric to be re-deposited onto the down, which would reduce its loft and insulation. Therefore, they need to be avoided when cleaning down items.

Nikwax Down Wash™ has been specifically designed and optimized for down items. Use Nikwax Down Wash™ to thoroughly clean your down items safely, revitalizing insulation, breathability and DWR.

How you treat your down is as important as the products you use…

Wet down is heavy, so it is important to use the right wash cycle to ensure no damage occurs to your machine or your down items. A gentle cycle with a slow spin is recommended.

After washing it is important that down items are thoroughly rinsed and very thoroughly dried. Even if you treat your items by hand, spin drying is recommended using a slow spin 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. If items are spun too quickly while still holding a large amount of water it is possible that internal baffles may be broken.

Tumble drying is recommended to ensure that the down is dried thoroughly and as quickly as possible. Leaving down wet or damp can ruin it completely.

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 the drying process will help restore loft to the down.

It is recommended that larger items are cleaned & waterproofed professionally.

How Nikwax Down Wash™ maintains your down items...

Nikwax Down Wash™ has been specifically designed and optimized for down filled gear. It is a highly effective cleaner which removes body oils and dirt from both the fabric and the down fill. It also revitalizes the existing Durable Water Repellency (DWR) of both the outer fabric and the down. This protects against rain and condensation, preventing the item from wetting out and maintaining the natural insulating properties of down. Additionally it revives breathability, allowing moisture vapor to pass through the item, optimizing performance in cold and damp conditions.

Nikwax Down Wash™ prolongs the effective life of your down gear. It is the safe way to thoroughly clean your down clothing and equipment. Application in a washing machine is quick, easy, and ensures that the whole item is thoroughly cleaned.

  • Remove all detergent build-up from the detergent dispenser.
  • Place item(s) in washing machine.
  • Home washing machine*: Use 100ml for 1-3 items
  • Commercial Machine: Use 3fl oz (100ml) for 1-3 items/ 1 season sleeping bag, 5fl oz (150ml) for 4-6 items/2-4 season bag

  • For sleeping bags: Use 5fl oz (150ml) in 1.5 inch deep water in a bathtub.
  • Agitate to mix.
  • Rinse 3 times in clean water. For sleeping bags repeat rinsing process, drain and gently press bag to expel water.
  • To remove excess water transfer item(s) to a washing machine and run multiple spin cycles, each time incrementally increasing the spin speed.

Make sure to thoroughly dry your down filled gear...

If you intend to re-waterproof the washed item there is no need to dry it first.

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.

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.
