Where these two actually differ
- We flag Volatile organic compounds (VOCs) and inhalation risk, Flammability and fire risk, Skin and eye contact irritation and Fragrance allergen content on the Carbona 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 Carbona.
- The Carbona is liquid solvent-based stain remover where the Nikwax is wax-based waterproofing, 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 →
