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 Simple Green.
- We flag Surfactant skin and respiratory irritation and Residual surfactant in fabric after incomplete rinsing on the Simple Green and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Simple Green is aqueous cleaning solution, surfactants, water, which is most of the difference in these two grades.
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 →
