Where these two actually differ
- We flag Fragrance allergens (spearmint sage essential oils / synthetic fragrance), 1,4-dioxane (manufacturing contaminant in surfactants), Eye and mucous membrane irritation (surfactants and spray exposure) and Skin sensitization (sodium lauryl sulfate or related surfactants) on the Method 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 Method.
- The Method is Aqueous cleaning concentrate in spray bottle 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: 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 →
