Commercial Cleaning & Waterproofing

Waterproof clothing, equipment and horse rugs require the correct care to maintain their performance. Cleaning and waterproofing with Nikwax® ensures these items remain breathable and repel water.

Please find below instructions and dosage information for using Nikwax in a commercial washing machine.


  1. Remove all detergent build-up from the detergent dispenser.
  2. Load garments/rugs into machine. Items must be free to move in machine. If overloaded, movement will be restricted and coverage may be uneven.
  3. Wash according to care label using the appropriate Nikwax cleaning product.
  4. Follow with a separate wash cycle using the appropriate Nikwax waterproofing product.
  5. Air-dry or tumble dry if care label allows.
