Toy category product that adds or renews water repellency while reviving breathability for outdoor clothing. Comfortable, drier walks and longer-lasting jackets for people who spend time outdoors are the main benefit. Does Nikwax Tx Direct Wash-In Waterproofer suit routine maintenance and real-world wet-weather use?

⚡ At a Glance
  • Water Repellency: Adds or renews water repellency while reviving breathability
  • Best for: Owners of coats and jackets that need restored waterproofing after wear
  • Not ideal for: Users who prefer solvent-based or fluorocarbon treatments

Wash-in treatment renews water repellency and restores breathable performance for outer layers. Formulated as water-based and fluorocarbon-free.


Restores waterproofing - thanks to a wash-in repellent formulation

Wash-in chemistry disperses evenly through the outer fabric during a machine wash or hand wash, re-establishing surface repellency across fibres. The process renews the fabric surface so water beads rather than soaks in.

Renewed repellency keeps rain beading on jackets and reduces wetting on long walks, so clothing dries faster and feels lighter when worn.

Keeps breathability intact - with a water-based, fluorocarbon-free formula

Water-based materials refresh repellency without relying on solvent or fluorocarbon chemistry, and the formulation is specified to revive breathability. That avoids clogging breathable membrane surfaces.

Breathable performance stays usable during activity, so perspiration can escape and comfort on the move is maintained.

Simple maintenance routine - with machine or hand application and no heat activation

Application works either by adding the solution to a washing machine cycle or by applying by hand, and the treatment requires no heat activation. The absence of a heat step removes the need for tumble-drying or ironing to set the finish.

Household laundering is sufficient for regular care, making reproofing quick and practical between outdoor trips.
