NIKWAX Nubuck & Suede Waterproofing Spray
A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.
Nikwax says it has never used PFAS in any of its products. We record that as an unverified brand claim. Its record describes a water-repellent or grease-resistant treatment of unstated chemistry, which is still counted.
Brand says: “Nikwax says it has never used PFAS in any of its products.”

What NIKWAX Nubuck & Suede Waterproofing Spray is made of, ingredients and materials
Nikwax Nubuck & Suede Waterproofing Spray's active waterproofing ingredient is not disclosed on public labeling, making independent assessment of its chemistry impossible. The product is formulated as a solvent-based spray designed to coat delicate napped leather surfaces without darkening or stiffening them. The brand claims PFAS-free formulation, but the specific replacement chemistries (likely hydrocarbon or silicone-based water repellents) are not stated, limiting verification of that claim against public data.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Solvent inhalation (VOC/respiratory irritation)
Spray format with undisclosed solvent carrier means volatile organic compound exposure during application is inherent; adequate ventilation is essential to minimize inhalation risk, especially in enclosed spaces.
Skin/eye contact from overspray
Spray application carries risk of accidental contact with skin or eyes if misdirected; product safety data sheet is not available in public records, so irritancy grade of the formulation is unknown.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Coating durability and degradation products
No public record of the treated coating breaking down into toxic secondary products over time; this is typical for water-repellent niche and does not appear to be a tracked hazard for this product.
Heavy metals
Waterproofing sprays for leather do not typically contain pigments; no public recalls or testing reports suggest heavy metal contamination in Nikwax products of this type.
Source, FDA ↗Formaldehyde / VOCs
Not typical in spray waterproofing formulations; no public evidence of formaldehyde-releasing additives in this product or category.

The brand's record and disclosure
Nikwax is known for transparency initiatives around fluorocarbon use and has made public statements positioning its products as PFAS-free alternatives, though independent third-party testing of this claim is not on public record. The company has a history of focusing on performance in outdoor/technical footwear markets and has not faced major product safety recalls related to this category. Ingredient disclosure remains minimal, typical of the waterproofing spray category, which limits evaluation of other potential hazards such as solvent type or volatile organic compounds.
How it compares in its category
Solvent-based waterproofing sprays for suede and nubuck are a common category; many traditional competitors use fluorocarbon (PFAS) chemistry, making a claimed PFAS-free spray a meaningful differentiation. Wax-based and silicone-based alternatives exist but are less common for napped leathers. Nikwax's positioning in the mid-market technical segment suggests it competes on performance claims rather than hazard minimization marketing; comparative safety data between PFAS-free spray products in this niche is not publicly available.
If you buy it
Use the spray in a well-ventilated outdoor area or room; inhalation of solvent vapors is the primary exposure route during application. Apply according to label instructions (usually 2-3 light coats, allowing drying between applications) and allow full cure time before wearing treated shoes. Reapply as water beads cease to form on the surface, typically every 6-12 months depending on use. Store in a cool, dry place away from ignition sources, as spray cans are pressurized and solvent-flammable.
