Nikwax Down Wash liquid cleaner 1L — gentle PFAS-free detergent for down jackets & sleeping bags, preserves loft

Nikwax Down Wash 1L is a purpose-made liquid cleaner that safely cleans down-filled jackets, sleeping bags and bedding while helping preserve loft and performance.

Regular household detergents can leave residues that attract water and reduce insulation. Nikwax Down Wash is formulated to remove dirt, body oils and contaminants from down and its outer fabrics without stripping natural loft or the performance of water-resistant down treatments. This water-based, PFAS-free formula is designed for machine and gentle hand washing and is free from optical brighteners and added fragrances.

How does Nikwax Down Wash clean down without harming loft?

The formula uses surfactants chosen to loosen and lift dirt without coating down fibers, so loft and warmth are retained. It rinses clearly to avoid water-attracting residues that common detergents can leave behind.

• Removes body oils and grime that compress down clumps
• Rinses clean to maintain natural loft and insulating air pockets
• Safe for both down fill and the garment’s outer fabric
• Suitable for machine wash cycles or gentle hand washing

Will this product work with water-resistant or hydrophobic down?

Yes — Down Wash is compatible with conventional and hydrophobic down types, including treated fills. It cleans without stripping specialist treatments, so performance of water-resistant down remains intact when used as directed.

• Recommended for down, down blends and water-resistant down fills
• Preserves factory-applied hydrophobic treatments when rinsed properly
• Safe for both technical outer fabrics and shell materials

How should I measure and apply Down Wash for best results?

One full cap equals about 50 ml, making it easy to dose for different load sizes. Use the recommended dosage on the bottle, run a normal wash cycle for machine washing, or agitate gently by hand and rinse thoroughly to remove all detergent.

• One full cap ≈ 50 ml for simple measuring
• Use machine wash or hand wash on gentle settings
• Rinse thoroughly to avoid residue and ensure loft recovery

Is Nikwax Down Wash safe and environmentally considerate?

Nikwax formulates this cleaner to be water-based, PFAS-free and without optical brighteners or added scent. These choices reduce persistent chemicals and avoid unnecessary additives while still delivering effective cleaning for performance gear.

• PFAS-free and non-persistent ingredients
• No optical brighteners or added fragrances
• Designed to be safe for routine machine washing of technical gear

Who is this for? Hikers, mountaineers, campers and everyday users who own down jackets, parkas, sleeping bags or bedding will benefit from Nikwax Down Wash. It’s meant for anyone wanting to extend the life and thermal performance of down-filled gear by removing contaminants that reduce loft, while avoiding harsh chemicals that can damage fill or treatments. Use it when gear looks soiled, after cold-season storage, or as part of routine care to maintain comfort and performance.
