Frequently Asked Questions

• What is Nikwax's TX.10i technology and how does it work?

  Nikwax's TX.10i is an elastic, water‑repellent polymer system (based on EVA materials) that forms a flexible, breathable barrier on fabrics and leathers. It repels liquid water while allowing moisture vapor to escape, and because it's water‑based and non‑fluorocarbon it works without heat activation.
• Are Nikwax products environmentally friendly and safe to use on technical gear?

  Yes, Nikwax formulations are PFC/PFAS‑free, biodegradable, water‑based and non‑flammable, and the company states they do not test on animals. Their non‑aerosol liquids are designed to be compatible with common membrane fabrics like Gore‑Tex®, eVent®, and Windstopper®.
• How do I use Tech Wash and TX.Direct to restore a waterproof jacket?

  Clean first with Tech Wash to remove dirt, oils and detergent residues that break down DWR, then apply TX.Direct Wash‑In or TX.Direct Spray‑On following the label instructions to restore repellency. Both steps can be done by hand or in a standard washing machine and do not require heating to activate.
• Will Nikwax treatments affect breathability or the loft of down garments?

  Nikwax products are formulated to maintain breathability—TX.10i polymers remain flexible so vapor transfer is preserved—and Down Wash Direct specifically cleans and reproofs down without stripping natural loft. For footwear, Fabric & Leather Proof adds repellency while aiming to keep leather and fabrics breathable.
• How long do Nikwax treatments last and how do I know when to reapply?

  Treatment longevity depends on abrasion, frequency of washing and contamination, but Nikwax formulas are designed to remain effective through multiple washes rather than needing reapplication after every wash. Reapply when water no longer beads or starts wetting out the fabric—use TX.Direct for shells, Down Wash Direct for down, and Fabric & Leather Proof for footwear.
