Why this grade

Where these two actually differ

  • We flag Fragrance allergens (spearmint sage blend) and Surfactant skin and eye irritation on direct contact on the Method and not on the Nikwax.
  • We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Method.
  • The Method is Liquid detergent concentrate (surfactants, water, fragrance) where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
