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 Shoe MGK.
- We flag Volatile organic compounds (VOCs) in solvent base, Fragrance allergens and sensitizers and Spray propellant or inhalation risk on the Shoe MGK and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Shoe MGK is cleaning solution, protective spray, brush (unspecified components), which is most of the difference in these two grades.
- We are less certain about the Shoe MGK grade, at 35% confidence against 78%, because it discloses less.
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 →
