Where these two actually differ
- We flag Inhalation exposure during spray application, Acute respiratory irritation from propellants and solvents, Skin and eye contact from spray overspray and Bioaccumulation potential of PFAS in treated fabrics 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 Water-repellent spray treatment (DWR) 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 →
