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 Resolve.
  • We flag Surfactant skin and respiratory irritation, Fragrance allergens and irritants, Residue buildup on carpet fibers and Undisclosed stain-guard additives (including possible fluorochemicals) on the Resolve and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the Resolve is Aqueous surfactant-based liquid cleaner, which is most of the difference in these two grades.
  • We are less certain about the Resolve 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 →
