Extreme Shield Protectant Car Cleaning Spray vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) and inhalation risk, Skin contact and residual film buildup and Fluorinated polymer persistence and bioaccumulation (PFAS-related) on the Armor All 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 Armor All.
• The Armor All is proprietary polymer spray coating/protectant 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 Armor All grade, at 35% confidence against 78%, because it discloses less.
