Product Details

Nikwax Cotton Proof™ has been specifically designed and optimised for breathable cotton, polycotton and canvas materials; it leaves a flexible water repellent treatment on individual fibres allowing moisture vapour to pass through, maintaining breathability, prolonging the life of gear and optimising performance in wet weather.

Nikwax Cotton Proof™ is easy and quick to apply in a washing machine and ensures that the treatment goes right through the garment. The highly Durable Water Repellency (DWR) of Nikwax Cotton Proof™ develops on air drying. Therefore the need for tumble drying is removed, saving energy.


How to apply:

To clothing

  1. Place clean item in a washing machine
  2. Apply Nikwax Cotton Proof in the machine’s dispenser
  3. Select a cotton wash cycle, start machine and complete rinse cycle
