Nikwax Nubuck & Suede Proof 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 Proof Spray is made of, ingredients and materials
Nikwax Nubuck & Suede Proof is a wax-based waterproofing spray formulated for delicate napped leathers (nubuck and suede). The active ingredient is a paraffin or plant-derived wax emulsion designed to bead water without saturating or darkening the nap texture. Wax-based treatments are inherently low-volatility and do not produce the fume profile of solvent-heavy or Teflon-family coating sprays, making inhalation exposure during application minimal by category standard.
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.
Volatile organic compounds (VOCs) from propellant or solvent carrier
Spray formulations typically use aerosol propellants or solvent carriers; Nikwax does not publicly disclose the propellant type. Exposure during application is localized but inhalation of spray mist is unavoidable without respiratory protection.
Skin or eye irritation from direct contact
Wax emulsions can cause mild irritation if sprayed directly onto skin or eyes. No specific incident reports for this product are on record, but standard precautions (wear gloves, apply outdoors) apply to all spray waterproofing products.
Uneven application or coating degradation over time
Wax-based coatings are more prone to wear and require more frequent reapplication than synthetic water-repellent coating finishes. User reports indicate the product loses water-beading performance within 6-12 months of use, necessitating retreat cycles.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Heavy metals
No recalls, test results, or published hazard data link Nikwax wax-based sprays to heavy metal contamination or undisclosed toxic additives. The brand's PFAS-free claim suggests intentional formulation away from fluorinated alternatives.

The brand's record and disclosure
Nikwax has publicly stated this product is PFAS-free, a claim we have not independently verified through third-party testing or regulatory filings. The brand markets transparency on waterproofing chemistry as a competitive position and has not reported recalls or safety controversies for this specific product. Nikwax holds ISO 14001 environmental management certification, though this does not address consumer product chemical safety independently.
How it compares in its category
Shoe waterproofing sprays range from fluorocarbon-based (water-repellent coating finishes with high PFAS risk) to silicone-based and wax-based formulas. Wax-based sprays like this one occupy the lower end of volatile organic compound and respiratory hazard risk compared to solvent-heavy competitors. Durability is typically shorter (requires reapplication every 6-12 months) but the trade-off is reduced acute chemical exposure during use and lower toxicological hazard profile.
If you buy it
Apply outdoors or in well-ventilated areas to minimize inhalation of any spray mist or propellant. Allow treated shoes to dry fully (24 hours) before wearing. Reapply every 6-12 months or when water no longer beads on the surface. Do not use on leather that is already wet or damaged, as wax will not adhere evenly and may cause staining.
