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 Shout.
- We flag Fluorinated stain-guard compounds (PFAS-adjacent), Surfactant skin irritation and sensitization, Fragrance allergens and Residual surfactant on fabric on the Shout and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Shout is Aqueous surfactant blend (liquid stain remover, no coating), which is most of the difference in these two grades.
- We are less certain about the Shout grade, at 45% 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 →
