Where these two actually differ
- We flag Inhalation risk from spray aerosol, Skin and eye irritation from direct contact, Off-gassing and volatile organic compounds (VOCs) and Bioaccumulation and environmental persistence on the Granger's 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 Granger's.
- The Granger's is proprietary water-repellent treatment (DWR finish) where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
- We are less certain about the Granger's grade, at 45% confidence against 78%, because it discloses less.
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 →
