Fabric Defense & Upholstery Protector Blocks Stains and Repels Liquid vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Inhalation of aerosolized fluoropolymers during spray application, Dermal and oral contact from treated fabric (especially children/pets) and Aquatic and soil contamination after disposal or laundry runoff on the Guardsman and not on the Nikwax.
• We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Guardsman.
• The Guardsman is Unknown liquid/stain repellent coating (likely fluorinated polymer) where the Nikwax is wax-based waterproofing, 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 Guardsman grade, at 42% confidence against 78%, because it discloses less.
