Where these two actually differ

  • We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Scotchgard.
  • We flag Inhalation exposure from aerosol spray, Off-gassing or VOC emissions post-application and Persistence in treated fabric and laundering runoff on the Scotchgard and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the Scotchgard is Fluorochemical water and stain repellent coating, 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 Scotchgard grade, at 45% confidence against 78%, because it discloses less.

Both products run through the same public rubric, which covers 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 →
