Waterproofing Wax for Leather vs Fabric Waterproofing Spray Stain Repellent for Outdoor Textiles, Water Protection Spray for Furniture Upholstery, Leathe: which is safer?

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 .
• We flag Volatile organic compounds (VOCs) in solvent carrier, Fluorinated compound residue on treated fabric (non-PFAS related hazard), Inhalation risk from aerosol or pump spray dispersion and Skin and eye irritation from spray contact on the and not on the Nikwax.
• The Nikwax is wax-based waterproofing where the is proprietary waterproofing spray coating, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
• We are less certain about the grade, at 35% confidence against 78%, because it discloses less.
