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 Surfactant identity and irritancy, Proprietary additive hazards (solvents, enzymes, brighteners), Spray inhalation risk and Skin and eye contact irritation on the Shout and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Shout is aqueous liquid stain remover (surfactants, water, proprietary additives), which is most of the difference in these two grades.
- We are less certain about the Shout 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 →
