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 Acute ingestion risk (anionic surfactants), Eye irritation (surfactants and fragrance) and Fragrance allergens and sensitizers 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.

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 →
