Nikwax grades Good on our four-band scale. On disclosure, the brand claims its products are PFAS-free (self-declared). See what every brand has published about PFAS for how that compares.

PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.

What Nikwax says and does about PFAS

Nikwax says it has never used PFAS in any of its products and never will. That is the company’s own claim, and we found no independent test of its waterproofing products for PFAS.

Sources checked September 14, 2026. A brand statement is the company’s own claim, which we report but have not verified. Our grades are model-based estimates, not lab tests.

Nikwax is one of the brands we researched by hand for our record of what every brand has published about PFAS, where the same question is answered for each of them in one line.
